# Bekerja dengan formulir

Tentang dokumen ini

This document provides an introduction to the basics of web forms and how they are handled in Django. For a more detailed look at specific areas of the forms API, see API Formulir, Bidang formulir, and Pengesahan formulir dan bidang.

Unless you're planning to build websites and applications that do nothing but publish content, and don't accept input from your visitors, you're going to need to understand and use forms.

Django provides a range of tools and libraries to help you build forms to accept input from site visitors, and then process and respond to the input.

## Formulir HTML

In HTML, a form is a collection of elements inside `<form>...</form>` that allow a visitor to do things like enter text, select options, manipulate objects or controls, and so on, and then send that information back to the server.

Some of these form interface elements - text input or checkboxes - are built into HTML itself. Others are much more complex; an interface that pops up a date picker or allows you to move a slider or manipulate controls will typically use JavaScript and CSS as well as HTML form `<input>` elements to achieve these effects.

Sama halnya dengan unsur `<input>`, sebuah formulir harus menentukan dua hal:

- dimana URL dimana data sesuai ke masukan pengguna harus kembali
- bagaimana: Metode HTTP data harus kembali

As an example, the login form for the Django admin contains several `<input>` elements: one of `type="text"` for the username, one of `type="password"` for the password, and one of `type="submit"` for the "Log in" button. It also contains some hidden text fields that the user doesn't see, which Django uses to determine what to do next.

It also tells the browser that the form data should be sent to the URL specified in the `<form>`’s `action` attribute - `/admin/` - and that it should be sent using the HTTP mechanism specified by the `method` attribute - `post`.

Ketika unsur `1` dipicu, data dikembalikan ke `/admin`.

### `GET` dan `POST`

`GET` dan `POST` adalah hanya cara HTTP digunakan untuk berhubungan dengan formulir.

Django's login form is returned using the `POST` method, in which the browser bundles up the form data, encodes it for transmission, sends it to the server, and then receives back its response.

`GET`, by contrast, bundles the submitted data into a string, and uses this to compose a URL. The URL contains the address where the data must be sent, as well as the data keys and values. You can see this in action if you do a search in the Django documentation, which will produce a URL of the form `https://docs.djangoproject.com/search/?q=forms&release=1`.

`GET` and `POST` adalah khususnya digunakan untuk tujuan berbeda.

Any request that could be used to change the state of the system - for example, a request that makes changes in the database - should use `POST`. `GET` should be used only for requests that do not affect the state of the system.

`GET` would also be unsuitable for a password form, because the password would appear in the URL, and thus, also in browser history and server logs, all in plain text. Neither would it be suitable for large quantities of data, or for binary data, such as an image. A web application that uses `GET` requests for admin forms is a security risk: it can be easy for an attacker to mimic a form's request to gain access to sensitive parts of the system. `POST`, coupled with other protections like Django's CSRF protection offers more control over access.

On the other hand, `GET` is suitable for things like a web search form, because the URLs that represent a `GET` request can easily be bookmarked, shared, or resubmitted.

## Peran Django di formulir

Handling forms is a complex business. Consider Django's admin, where numerous items of data of several different types may need to be prepared for display in a form, rendered as HTML, edited using a convenient interface, returned to the server, validated and cleaned up, and then saved or passed on for further processing.

Django's form functionality can simplify and automate vast portions of this work, and can also do it more securely than most programmers would be able to do in code they wrote themselves.

Django menangani tiga bagian berbeda dari pekerjaan melibatkan dalam formulir-formulir:

- mempersiapkan dan menyusun kembali data untuk membuat itu untuk pengiriman
- membuat formulir HTML untuk data
- menerima dan mengolah formulir-formulir diajukan dan data dari klien

Itu memungkinkan menulis kode yang melakukan semua ini secara manual, tetapi Django dapat merawat itu semua untuk anda.

## Formulir di Django

Kami telah menggambarkan formulir HTML dengan ringkas, tetapi sebuah HTML `1` hanya satu bagian dari mesin yang dibutuhkan.

In the context of a web application, 'form' might refer to that HTML `<form>`, or to the Django `Form` that produces it, or to the structured data returned when it is submitted, or to the end-to-end working collection of these parts.

### Kelas `Form` Django

At the heart of this system of components is Django's `Form` class. In much the same way that a Django model describes the logical structure of an object, its behavior, and the way its parts are represented to us, a `Form` class describes a form and determines how it works and appears.

In a similar way that a model class's fields map to database fields, a form class's fields map to HTML form `<input>` elements. (A `ModelForm` maps a model class's fields to HTML form `<input>` elements via a `Form`; this is what the Django admin is based upon.)

A form's fields are themselves classes; they manage form data and perform validation when a form is submitted. A `DateField` and a `FileField` handle very different kinds of data and have to do different things with it.

A form field is represented to a user in the browser as an HTML "widget" - a piece of user interface machinery. Each field type has an appropriate default Widget class, but these can be overridden as required.

### Mengawali, mengolah, dan membangun formulir

Ketika membangun sebuah obyek di Django, kami umumnya:

1. get hold of it in the view (fetch it from the database, for example)
2. lewatkan ke konteks cetakan
3. perluas itu pada markah HTML menggunakan variabel cetakan

Membangun formulir dalam cetakan melibatkan hampir pekerjaan sama seperti membangun jenis lain dari obyek, tetapi ada beberapa kunci perbedaan.

In the case of a model instance that contained no data, it would rarely if ever be useful to do anything with it in a template. On the other hand, it makes perfect sense to render an unpopulated form - that's what we do when we want the user to populate it.

Jadi ketika kami menangani instance model dalam tampilan, kami khususnya mengambil itu dari basisdata. Ketika kami sedang berhubungan dengan seuah formulir kami khususnya menginstansiasi itu dalam tampilan.

When we instantiate a form, we can opt to leave it empty or prepopulate it, for example with:

- data dari instance model tersimpan (seperti dalam kasus dari formulir admin untuk penyuntingan).
- data yang kami telah kumpulkan dari sumber lain
- data diterima dari pengajuan formulir HTML sebelumnya

Kasus terakhir ini paling menarik, karena itu memungkinkan untuk pengguna tidak hanya membaca jaringan situs, tetapi juga mengirim informasi kembali ke jaringan situs.

## Membangun formulir

### Pekerjaan yang butuh diselesaikan

Misalnya anda ingin membuat sebuah formulir sederhana pada situs jaringan anda, untuk mendapatkan nama pengguna, anda akan butuh sesuatu seperti ini di cetakan anda:

    <form action="/your-name/" method="post">
        <label for="your_name">Your name: </label>
        <input id="your_name" type="text" name="your_name" value="{{ current_name }}">
        <input type="submit" value="OK">
    </form>

Ini memberitahukan perambah untuk mengembalikan data formulir ke URL `/your-name/`, menggunakan cara `POST`. Dia akan menampilkan bidang teks, label "Nama anda:", dan tombol ditandai "OK". Jika konteks cetakan mengandung variabel `current_name`, yang akan digunakan untuk pra-isian bidang `your_name`.

Anda akan butuh sebuah tampilan yang membangun cetakan mengandung formulir HTML, dan dapat mendukung bidang `current_name` sewajarnya.

Ketika formulir diajukan, permintaan `POST` yang dikirim ke peladen akan mengandung data formulir.

Sekarang anda akan juga butuh sebuah tampilan sesuai ke URL `/your-name/` yang akan menemukan pasangan kunci/nilai yang sesuai di permintaan, dan kemudian mengolah mereka.

This is a very simple form. In practice, a form might contain dozens or hundreds of fields, many of which might need to be prepopulated, and we might expect the user to work through the edit-submit cycle several times before concluding the operation.

Kami mungkin membutuhkan beberapa pengesahan untuk muncul dalam peramban, bahkan sebelum formulir diajukan; kami mungkin ingin menggunakan bidang-bdiang lebih rumit, yang mengizinkan pengguna melakukan hal-hal seperti mengambil tanggal dari kalender dan seterusnya.

Pada titik ini itu lebih mudah mendapatkan Django melakukan kebanyakan dari pekerjaan ini untuk kita.

### Membangun formulir di Django

#### Kelas `Form`

Kami sudah mengetahui apa kami inginkan formulir HTML kami terlihat seperti. Titik mulai kami untuk itu di Django adalah ini:

`forms.py`

    from django import forms

    class NameForm(forms.Form):
        your_name = forms.CharField(label="Your name", max_length=100)

Ini menentukan kelas `Form` dengan bidang tunggal (`your_name`). Kami telah berlakukan label ramah-manusia pada bidang, yang akan muncul dalam `1` ketika itu dibangun (meskipun dalam kasus ini, `label` kami tentukan sebenarnya sama satu yang akan dibangkitkan otomatis jika kami telah menghilangkan itu).

Panjang masimal bidang diizinkan ditentukan oleh `max_length`. Ini melakukan dua hal. Itu menaruh `maxlength="100"` pada HTML `1` (jadi peramban harus mencegah pengguna dari memasuki ebih dari sejumlah karakter dalam tempat pertama). Itu juga berarti bahwa ketika Django menerima formulir kembali dari peramban, itu akan mensahkan panjang dari data.

Sebuah instance `Form` mempunyai sebuah metode `is_valid()`, yang menjalankan fungsi untuk semua bidang-bidangnya. Ketika metode ini dipanggil, jika semua bidang mengadnung data sah, itu akan:

- kembali `True`
- tempatkan data formulir dalam atribut `cleaned_data` nya.

Formulir keseluruhan, ketika dibangun untuk pertama kali, akan kelihatan seperti:

    <label for="your_name">Your name: </label>
    <input id="your_name" type="text" name="your_name" maxlength="100" required>

Note that it does not include the `<form>` tags, or a submit button. We'll have to provide those ourselves in the template.

#### Tampilan

Form data sent back to a Django website is processed by a view, generally the same view which published the form. This allows us to reuse some of the same logic.

To handle the form we need to instantiate it in the view for the URL where we want it to be published:

`views.py`

    from django.http import HttpResponseRedirect
    from django.shortcuts import render

    from .forms import NameForm

    def get_name(request):
        # if this is a POST request we need to process the form data
        if request.method == "POST":
            # create a form instance and populate it with data from the request:
            form = NameForm(request.POST)
            # check whether it's valid:
            if form.is_valid():
                # process the data in form.cleaned_data as required
                # ...
                # redirect to a new URL:
                return HttpResponseRedirect("/thanks/")

        # if a GET (or any other method) we'll create a blank form
        else:
            form = NameForm()

        return render(request, "name.html", {"form": form})

If we arrive at this view with a `GET` request, it will create an empty form instance and place it in the template context to be rendered. This is what we can expect to happen the first time we visit the URL.

If the form is submitted using a `POST` request, the view will once again create a form instance and populate it with data from the request: `form = NameForm(request.POST)` This is called "binding data to the form" (it is now a bound form).

We call the form's `is_valid()` method; if it's not `True`, we go back to the template with the form. This time the form is no longer empty (unbound) so the HTML form will be populated with the data previously submitted, where it can be edited and corrected as required.

If `is_valid()` is `True`, we'll now be able to find all the validated form data in its `cleaned_data` attribute. We can use this data to update the database or do other processing before sending an HTTP redirect to the browser telling it where to go next.

#### Cetakan

Kami tidak perlu melakukan banyak dalam cetakan``name.html``kami:

    <form action="/your-name/" method="post">
        {% csrf_token %}
        {{ form }}
        <input type="submit" value="Submit">
    </form>

Semua bidang formulir dan atribut mereka akan dikeluarkan kedalam markah HTML dari `{{ form }}` itu dengan bahasa cetakan Django.

Perlindungan formulir dan pemalsuan Cross Site Request

Django ships with an easy-to-use protection against Cross Site Request Forgeries. When submitting a form via `POST` with CSRF protection enabled you must use the `csrf_token` template tag as in the preceding example. However, since CSRF protection is not directly tied to forms in templates, this tag is omitted from the following examples in this document.

jenis masukan HTML5 dan pengesahan perambah

If your form includes a `URLField`, an `EmailField` or any integer field type, Django will use the `url`, `email` and `number` HTML5 input types. By default, browsers may apply their own validation on these fields, which may be stricter than Django's validation. If you would like to disable this behavior, set the `novalidate` attribute on the `form` tag, or specify a different widget on the field, like `TextInput`.

Kami sekarang memiliki formulir jaringan yang bekerja, digambarkan oleh Django `Form`, diolah oleh tampilan, dan dibangun sebagai HTML `<form>`.

That's all you need to get started, but the forms framework puts a lot more at your fingertips. Once you understand the basics of the process described above, you should be prepared to understand other features of the forms system and ready to learn a bit more about the underlying machinery.

## Lebih tentang kelas Django `Form`.

All form classes are created as subclasses of either `django.forms.Form` or `django.forms.ModelForm`. You can think of `ModelForm` as a subclass of `Form`. `Form` and `ModelForm` actually inherit common functionality from a (private) `BaseForm` class, but this implementation detail is rarely important.

Model dan Formulir

In fact if your form is going to be used to directly add or edit a Django model, a ModelForm can save you a great deal of time, effort, and code, because it will build a form, along with the appropriate fields and their attributes, from a `Model` class.

### Instance formulir terikat dan tidak terikat

Perbedaan diantara Bound and unbound forms adalah penting:

- Sebuah formulir tidak terikat tidak mempunyai data terkait dengan itu. Ketika dibanguk ke pengguna, itu akan kosong atau mengandung nilai awalan.
- Sebuah formulir ikatan telah mengajukan data, dan kemudian dapat digunakan untuk memberitahu jika data adalah sah. Jika sebuah ikatan tidak sah dibangun, itu dapat menyertakan pesan-pesan kesalahan berderet mengatakan pengguna apa yang data untuk diperbaiki.

Atribut formulir `is_bound` akan memberitahu anda apakah sebuah formulir mempunyai data terikat ke itu atau tidak.

### Lebih pada bidang

Pertimbangkan formulir lebih berguna dari contoh minimal kami diatas, yang kami dapat gunakan untuk menerapkan kegunaan "hubungi kami" pada situs jaringan pribadi:

`forms.py`

    from django import forms

    class ContactForm(forms.Form):
        subject = forms.CharField(max_length=100)
        message = forms.CharField(widget=forms.Textarea)
        sender = forms.EmailField()
        cc_myself = forms.BooleanField(required=False)

Our earlier form used a single field, `your_name`, a `CharField`. In this case, our form has four fields: `subject`, `message`, `sender` and `cc_myself`. `CharField`, `EmailField` and `BooleanField` are just three of the available field types; a full list can be found in Bidang formulir.

#### Widget

Setiap bidang formulir mempunyai Widget class 1 sesuai, yang gilirannya sesuai pada sebuah widget formulir HMTL seperti `2`.

In most cases, the field will have a sensible default widget. For example, by default, a `CharField` will have a `TextInput` widget, that produces an `<input type="text">` in the HTML. If you needed `<textarea>` instead, you'd specify the appropriate widget when defining your form field, as we have done for the `message` field.

#### Bidang data

Whatever the data submitted with a form, once it has been successfully validated by calling `is_valid()` (and `is_valid()` has returned `True`), the validated form data will be in the `form.cleaned_data` dictionary. This data will have been nicely converted into Python types for you.

Catatan

Anda masih dapat mengakses data tidak tersahkan langsung dari `request.POST` pada titik ini, tetapi data tersahkan adalah lebih baik.

In the contact form example above, `cc_myself` will be a boolean value. Likewise, fields such as `IntegerField` and `FloatField` convert values to a Python `int` and `float` respectively.

Ini adalah bagaimana formulir dapat dapat diolah dalam tampilan yang menangani formulir ini:

`views.py`

    from django.core.mail import send_mail

    if form.is_valid():
        subject = form.cleaned_data["subject"]
        message = form.cleaned_data["message"]
        sender = form.cleaned_data["sender"]
        cc_myself = form.cleaned_data["cc_myself"]

        recipients = ["info@example.com"]
        if cc_myself:
            recipients.append(sender)

        send_mail(subject, message, sender, recipients)
        return HttpResponseRedirect("/thanks/")

Tip

Untuk lebih pada mengirim surel dari Django, lihat Mengirim surel.

Some field types need some extra handling. For example, files that are uploaded using a form need to be handled differently (they can be retrieved from `request.FILES`, rather than `request.POST`). For details of how to handle file uploads with your form, see Mengikat berkas terunggah ke formulir.

## Bekerja dengan cetakan formulir

All you need to do to get your form into a template is to place the form instance into the template context. So if your form is called `form` in the context, `{{ form }}` will render its `<label>` and `<input>` elements appropriately.

Tambahan formulir cetakan mebel

Don't forget that a form's output does not include the surrounding `<form>` tags, or the form's `submit` control. You will have to provide these yourself.

### Formulir cetakan-cetakan dapat digunakan kembali

The HTML output when rendering a form is itself generated via a template. You can control this by creating an appropriate template file and setting a custom `FORM_RENDERER` to use that `form_template_name` site-wide. You can also customize per-form by overriding the form's `template_name` attribute to render the form using the custom template, or by passing the template name directly to `Form.render()`.

The example below will result in `{{ form }}` being rendered as the output of the `form_snippet.html` template.

Dalam cetakan anda:

    # In your template:
    {{ form }}

    # In form_snippet.html:
    {% for field in form %}
        <div class="fieldWrapper">
            {{ field.errors }}
            {{ field.label_tag }} {{ field }}
        </div>
    {% endfor %}

Then you can configure the `FORM_RENDERER` setting:

`settings.py`

    from django.forms.renderers import TemplatesSetting

    class CustomFormRenderer(TemplatesSetting):
        form_template_name = "form_snippet.html"

    FORM_RENDERER = "project.settings.CustomFormRenderer"

… or for a single form:

    class MyForm(forms.Form):
        template_name = "form_snippet.html"
        ...

… or for a single render of a form instance, passing in the template name to the `Form.render()`. Here's an example of this being used in a view:

    def index(request):
        form = MyForm()
        rendered_form = form.render("form_snippet.html")
        context = {"form": rendered_form}
        return render(request, "index.html", context)

See Mengeluarkan formulir sebagai HTML for more details.

Changed in Django 4.1:

The ability to set the default `form_template_name` on the form renderer was added.

### Formulir pilihan pembangunan

Ada pilihan keluaran lain meskipun untuk pasangan `1`/`2`:

- `{{ form.as_div }}` will render them wrapped in `<div>` tags.
- `{{ form.as_table }}` will render them as table cells wrapped in `<tr>` tags.
- `{{ form.as_p }}` will render them wrapped in `<p>` tags.
- `{{ form.as_ul }}` will render them wrapped in `<li>` tags.

Catat bahwa anda harus menyediakan sekitarnya unsur `1` atau `2` anda sendiri.

Ini adalah keluaran dari `{{ form.as_p }}` untuk instance `ContactForm` kami:

    <p><label for="id_subject">Subject:</label>
        <input id="id_subject" type="text" name="subject" maxlength="100" required></p>
    <p><label for="id_message">Message:</label>
        <textarea name="message" id="id_message" required></textarea></p>
    <p><label for="id_sender">Sender:</label>
        <input type="email" name="sender" id="id_sender" required></p>
    <p><label for="id_cc_myself">Cc myself:</label>
        <input type="checkbox" name="cc_myself" id="id_cc_myself"></p>

Note that each form field has an ID attribute set to `id_<field-name>`, which is referenced by the accompanying label tag. This is important in ensuring that forms are accessible to assistive technology such as screen reader software. You can also customize the way in which labels and ids are generated.

Lihat Mengeluarkan formulir sebagai HTML untuk lebih pada ini.

### Membangun bidang manual

We don't have to let Django unpack the form's fields; we can do it manually if we like (allowing us to reorder the fields, for example). Each field is available as an attribute of the form using `{{ form.name_of_field }}`, and in a Django template, will be rendered appropriately. For example:

    {{ form.non_field_errors }}
    <div class="fieldWrapper">
        {{ form.subject.errors }}
        <label for="{{ form.subject.id_for_label }}">Email subject:</label>
        {{ form.subject }}
    </div>
    <div class="fieldWrapper">
        {{ form.message.errors }}
        <label for="{{ form.message.id_for_label }}">Your message:</label>
        {{ form.message }}
    </div>
    <div class="fieldWrapper">
        {{ form.sender.errors }}
        <label for="{{ form.sender.id_for_label }}">Your email address:</label>
        {{ form.sender }}
    </div>
    <div class="fieldWrapper">
        {{ form.cc_myself.errors }}
        <label for="{{ form.cc_myself.id_for_label }}">CC yourself?</label>
        {{ form.cc_myself }}
    </div>

Complete `<label>` elements can also be generated using the `label_tag()`. For example:

    <div class="fieldWrapper">
        {{ form.subject.errors }}
        {{ form.subject.label_tag }}
        {{ form.subject }}
    </div>

#### Membangun formulir kesalahan pesan

The price of this flexibility is a bit more work. Until now we haven't had to worry about how to display form errors, because that's taken care of for us. In this example we have had to make sure we take care of any errors for each field and any errors for the form as a whole. Note `{{ form.non_field_errors }}` at the top of the form and the template lookup for errors on each field.

Using `{{ form.name_of_field.errors }}` displays a list of form errors, rendered as an unordered list. This might look like:

    <ul class="errorlist">
        <li>Sender is required.</li>
    </ul>

The list has a CSS class of `errorlist` to allow you to style its appearance. If you wish to further customize the display of errors you can do so by looping over them:

    {% if form.subject.errors %}
        <ol>
        {% for error in form.subject.errors %}
            <li><strong>{{ error|escape }}</strong></li>
        {% endfor %}
        </ol>
    {% endif %}

Non-field errors (and/or hidden field errors that are rendered at the top of the form when using helpers like `form.as_p()`) will be rendered with an additional class of `nonfield` to help distinguish them from field-specific errors. For example, `{{ form.non_field_errors }}` would look like:

    <ul class="errorlist nonfield">
        <li>Generic validation error</li>
    </ul>

Lihat API Formulir untuk lebih pada kesalahan, gaya, dan bekerja dengan atribut formulir dalam cetakan-cetakan.

### Memutar terhadap bidang-bidang formulir

Jika anda sedang menggunakan HTML sama untuk setiap bidang formulir anda, anda dapat mengurangi kode ganda dengan memutari setiap bidang bergantian menggunakan putaran `{% for %}`:

    {% for field in form %}
        <div class="fieldWrapper">
            {{ field.errors }}
            {{ field.label_tag }} {{ field }}
            {% if field.help_text %}
            <p class="help">{{ field.help_text|safe }}</p>
            {% endif %}
        </div>
    {% endfor %}

Atribut berguna pada `{{ field }}` termasuk:

`{{ field.errors }}`
  Outputs a `<ul class="errorlist">` containing any validation errors corresponding to this field. You can customize the presentation of the errors with a `{% for error in field.errors %}` loop. In this case, each object in the loop is a string containing the error message.
`{{ field.field }}`
  The `Field` instance from the form class that this `BoundField` wraps. You can use it to access `Field` attributes, e.g. `{{ char_field.field.max_length }}`.
`{{ field.help_text }}`
  Teks bantuan apapun yang telah dikaitkan dengan bidang.
`{{ field.html_name }}`
  The name of the field that will be used in the input element's name field. This takes the form prefix into account, if it has been set.
`{{ field.id_for_label }}`
  ID yang akan digunakan untuk bidang ini (`id_email` di contoh diatas). Jika anda sedang membangun label secara manual, anda mungkin ingin menggunakan ini sebagai pengganti `label_tag`. Itu juga sangat berguna, sebagai contoh, jika anda mempunyai beberapa JavaScript berderet dan ingin menghindari kode keras ID bidang.
`{{ field.is_hidden }}`
  This attribute is `True` if the form field is a hidden field and `False` otherwise. It's not particularly useful as a template variable, but could be useful in conditional tests such as:

    {% if field.is_hidden %}
       {# Do something special #}
    {% endif %}

`{{ field.label }}`
  Label dari bidang, sebagai contoh `Alamat surel`.
`{{ field.label_tag }}`

  The field's label wrapped in the appropriate HTML `<label>` tag. This includes the form's `label_suffix`. For example, the default `label_suffix` is a colon:

      <label for="id_email">Email address:</label>

`{{ field.legend_tag }}`

> New in Django 4.1.

> Similar to `field.label_tag` but uses a `<legend>` tag in place of `<label>`, for widgets with multiple inputs wrapped in a `<fieldset>`.

`{{ field.use_fieldset }}`

> New in Django 4.1.

> This attribute is `True` if the form field's widget contains multiple inputs that should be semantically grouped in a `<fieldset>` with a `<legend>` to improve accessibility. An example use in a template:

    {% if field.use_fieldset %}
      <fieldset>
      {% if field.label %}{{ field.legend_tag }}{% endif %}
    {% else %}
      {% if field.label %}{{ field.label_tag }}{% endif %}
    {% endif %}
    {{ field }}
    {% if field.use_fieldset %}</fieldset>{% endif %}

`{{ field.value }}`
  Nilai bidang sebagai contoh `someone@example.com`.

#### Berputar terhadap bidang-bdaing sembunyi dan tampak

If you're manually laying out a form in a template, as opposed to relying on Django's default form layout, you might want to treat `<input type="hidden">` fields differently from non-hidden fields. For example, because hidden fields don't display anything, putting error messages "next to" the field could cause confusion for your users -- so errors for those fields should be handled differently.

Django provides two methods on a form that allow you to loop over the hidden and visible fields independently: `hidden_fields()` and `visible_fields()`. Here's a modification of an earlier example that uses these two methods:

    {# Include the hidden fields #}
    {% for hidden in form.hidden_fields %}
    {{ hidden }}
    {% endfor %}
    {# Include the visible fields #}
    {% for field in form.visible_fields %}
        <div class="fieldWrapper">
            {{ field.errors }}
            {{ field.label_tag }} {{ field }}
        </div>
    {% endfor %}

This example does not handle any errors in the hidden fields. Usually, an error in a hidden field is a sign of form tampering, since normal form interaction won't alter them. However, you could easily insert some error displays for those form errors, as well.

## Topik lebih jauh

Ini mencangkup dasar, tetapi formulir dapat melakukan keseluruhan lebih banyak:
