Widget

A widget is Django's representation of an HTML input element. The widget handles the rendering of the HTML, and the extraction of data from a GET/POST dictionary that corresponds to the widget.

The HTML generated by the built-in widgets uses HTML5 syntax, targeting <!DOCTYPE html>. For example, it uses boolean attributes such as checked rather than the XHTML style of checked='checked'.

Menentukan widget

Whenever you specify a field on a form, Django will use a default widget that is appropriate to the type of data that is to be displayed. To find which widget is used on which field, see the documentation about KelaS-kelas Field siap-pakai.

Bagaimanapun, jika anda ingin menggunakan widget berbeda untuk bidang, anda cukup menggunakan argumen widget pada pengertian bidang. Sebagai contoh:

Code
from django import forms

class CommentForm(forms.Form):
    name = forms.CharField()
    url = forms.URLField()
    comment = forms.CharField(widget=forms.Textarea)

Ini akan menentukan formulir dengan komentar yang menggunakan widget Textarea terbesar, daripada widget TextInput awal.

Mengatur argumen untuk widget

Many widgets have optional extra arguments; they can be set when defining the widget on the field. In the following example, the years attribute is set for a SelectDateWidget:

Code
from django import forms

BIRTH_YEAR_CHOICES = ('1980', '1981', '1982')
FAVORITE_COLORS_CHOICES = (
    ('blue', 'Blue'),
    ('green', 'Green'),
    ('black', 'Black'),
)

class SimpleForm(forms.Form):
    birth_year = forms.DateField(widget=forms.SelectDateWidget(years=BIRTH_YEAR_CHOICES))
    favorite_colors = forms.MultipleChoiceField(
        required=False,
        widget=forms.CheckboxSelectMultiple,
        choices=FAVORITE_COLORS_CHOICES,
    )

Lihat Widget pasang tetap untuk informasi lebih tentang widget-widget mana tersedia dan argumen mana mereka terima.

Widget warisan dari widget Select

Widgets inheriting from the Select widget deal with choices. They present the user with a list of options to choose from. The different widgets present this choice differently; the Select widget itself uses a <select> HTML list representation, while RadioSelect uses radio buttons.

Widget Select digunakan secara awalan pada ChoiceField fields. Pilihan-pilihan ditampilkan pada widget diwariskan dari ChoiceField dan merubah ChoiceField.choices akan memperbaharui Select.choices. Sebagai contoh:

Code
>>> from django import forms
>>> CHOICES = (('1', 'First',), ('2', 'Second',))
>>> choice_field = forms.ChoiceField(widget=forms.RadioSelect, choices=CHOICES)
>>> choice_field.choices
[('1', 'First'), ('2', 'Second')]
>>> choice_field.widget.choices
[('1', 'First'), ('2', 'Second')]
>>> choice_field.widget.choices = ()
>>> choice_field.choices = (('1', 'First and only',),)
>>> choice_field.widget.choices
[('1', 'First and only')]

Widgets which offer a choices attribute can however be used with fields which are not based on choice -- such as a CharField -- but it is recommended to use a ChoiceField-based field when the choices are inherent to the model and not just the representational widget.

Menyesuaikan instance widget

When Django renders a widget as HTML, it only renders very minimal markup - Django doesn't add class names, or any other widget-specific attributes. This means, for example, that all TextInput widgets will appear the same on your Web pages.

Ada dua cara menyesuaikan widget: per widget instance dan per widget class.

Menggayakan instance widget

If you want to make one widget instance look different from another, you will need to specify additional attributes at the time when the widget object is instantiated and assigned to a form field (and perhaps add some rules to your CSS files).

Sebagai contoh, ambil formulir sederhana berikut:

Code
from django import forms

class CommentForm(forms.Form):
    name = forms.CharField()
    url = forms.URLField()
    comment = forms.CharField()

This form will include three default TextInput widgets, with default rendering -- no CSS class, no extra attributes. This means that the input boxes provided for each widget will be rendered exactly the same:

Code
>>> f = CommentForm(auto_id=False)
>>> f.as_table()
<tr><th>Name:</th><td><input type="text" name="name" required></td></tr>
<tr><th>Url:</th><td><input type="url" name="url" required></td></tr>
<tr><th>Comment:</th><td><input type="text" name="comment" required></td></tr>

On a real Web page, you probably don't want every widget to look the same. You might want a larger input element for the comment, and you might want the 'name' widget to have some special CSS class. It is also possible to specify the 'type' attribute to take advantage of the new HTML5 input types. To do this, you use the Widget.attrs argument when creating the widget:

Code
class CommentForm(forms.Form):
    name = forms.CharField(widget=forms.TextInput(attrs={'class': 'special'}))
    url = forms.URLField()
    comment = forms.CharField(widget=forms.TextInput(attrs={'size': '40'}))

Anda dapat juga merubah widget dalam pengertian formulir:

Code
class CommentForm(forms.Form):
    name = forms.CharField()
    url = forms.URLField()
    comment = forms.CharField()

    name.widget.attrs.update({'class': 'special'})
    comment.widget.attrs.update(size='40')

Atau jika bidang tidak dinyatakan langsung pada formulir (seperti bidang formulir model), anda dapat menggunakan atribut Form.fields:

Code
class CommentForm(forms.ModelForm):
    def __init__(self, *args, **kwargs):
        super().__init__(*args, **kwargs)
        self.fields['name'].widget.attrs.update({'class': 'special'})
        self.fields['comment'].widget.attrs.update(size='40')

Django kemudian akan menyertakan atribut tambahan dalam keluaran dibangun:

Code
>>> f = CommentForm(auto_id=False)
>>> f.as_table()
<tr><th>Name:</th><td><input type="text" name="name" class="special" required></td></tr>
<tr><th>Url:</th><td><input type="url" name="url" required></td></tr>
<tr><th>Comment:</th><td><input type="text" name="comment" size="40" required></td></tr>

Anda dapat juga mensetel id HTML menggunakan attrs. Lihat BoundField.id_for_label sebagai contoh.

Menggayakan kelas widget

Dengan widget, itu memungkinkan menambahkan assets (css dan javascript) dan lebih mendalam menyesuaikan penampilan dan perilaku mereka.

In a nutshell, you will need to subclass the widget and either define a "Media" inner class or create a "media" property.

These methods involve somewhat advanced Python programming and are described in detail in the Form Assets topic guide.

Kelas-kelas widget dasar

Base widget classes Widget and MultiWidget are subclassed by all the built-in widgets and may serve as a foundation for custom widgets.

Widget

class Widget(attrs=None)

This abstract class cannot be rendered, but provides the basic attribute attrs. You may also implement or override the render() method on custom widgets.

attrs

Sebuah dictionary mengandung atribut HTML untuk disetel pada widget dibangun.

Python console
>>> from django import forms
>>> name = forms.TextInput(attrs={'size': 10, 'title': 'Your name'})
>>> name.render('name', 'A name')
'<input title="Your name" type="text" name="name" value="A name" size="10">'

Jika anda memberikan sebuah nilai dari True atau False ke sebuah atribut, itu akan dibangun sebagai sebuah atribut boolean HTML5:

Code
>>> name = forms.TextInput(attrs={'required': True})
>>> name.render('name', 'A name')
'<input name="name" type="text" value="A name" required>'
>>>
>>> name = forms.TextInput(attrs={'required': False})
>>> name.render('name', 'A name')
'<input name="name" type="text" value="A name">'
supports_microseconds

Sebuah atribut yang awalan menjadi True. Jika disetel menjadi False, mikrodetik bagian dari nilai-nilai datetime dan time akan disetel menjadi 0.

format_value(value)

Cleans and returns a value for use in the widget template. value isn't guaranteed to be valid input, therefore subclass implementations should program defensively.

get_context(name, value, attrs)

Returns a dictionary of values to use when rendering the widget template. By default, the dictionary contains a single key, 'widget', which is a dictionary representation of the widget containing the following keys:

  • 'name': Nama dari bidang dari argumen name.

  • 'is_hidden': Sebuah boolean menunjukkan apakah atau tidak widget ini tersembunyi.

  • 'required': Sebuah boolean menunjukkan apakah atau tidak bidang untuk widget ini diwajibkan.

  • 'value': Nilai seperti dikembalikan oleh format_value().

  • 'attrs': Atribut-atribut HTML untuk disetel pada widget dibangun. Perpaduan dari atribut attrs dan argumen attrs.

  • 'template_name': Nilai dari self.template_name.

Subkelas-subkelas Widget dapat menyediakan penyesuaian nilai konteks dengan menimpa metode ini.

id_for_label(id_)

Mengebalikan atribut ID HTML dari widget ini untuk digunakan oleh sebuah <label>, diberikan ID dari bidang. Mengembalikan None jika sebuah ID tidak tersedia.

This hook is necessary because some widgets have multiple HTML elements and, thus, multiple IDs. In that case, this method should return an ID value that corresponds to the first ID in the widget's tags.

render(name, value, attrs=None, renderer=None)

Renders a widget to HTML using the given renderer. If renderer is None, the renderer from the FORM_RENDERER setting is used.

value_from_datadict(data, files, name)

Given a dictionary of data and this widget's name, returns the value of this widget. files may contain data coming from request.FILES. Returns None if a value wasn't provided. Note also that value_from_datadict may be called more than once during handling of form data, so if you customize it and add expensive processing, you should implement some caching mechanism yourself.

value_omitted_from_data(data, files, name)

Given data and files dictionaries and this widget's name, returns whether or not there's data or files for the widget.

Hasil metode mempengaruhi apakah atau tidak sebuah bidang di sebuah model formulir falls back to its default.

Special cases are CheckboxInput, CheckboxSelectMultiple, and SelectMultiple, which always return False because an unchecked checkbox and unselected <select multiple> don't appear in the data of an HTML form submission, so it's unknown whether or not the user submitted a value.

use_required_attribute(initial)

Given a form field's initial value, returns whether or not the widget can be rendered with the required HTML attribute. Forms use this method along with Field.required and Form.use_required_attribute to determine whether or not to display the required attribute for each field.

By default, returns False for hidden widgets and True otherwise. Special cases are ClearableFileInput, which returns False when initial is not set, and CheckboxSelectMultiple, which always returns False because browser validation would require all checkboxes to be checked instead of at least one.

Override this method in custom widgets that aren't compatible with browser validation. For example, a WSYSIWG text editor widget backed by a hidden textarea element may want to always return False to avoid browser validation on the hidden field.

MultiWidget

class MultiWidget(widgets, attrs=None)

A widget that is composed of multiple widgets. MultiWidget works hand in hand with the MultiValueField.

MultiWidget mempunyai satu argumen diwajibkan:

widgets

Sebuah perulangan mengandung widget dibutuhkan.

Dan satu cara diwajibkan:

decompress(value)

This method takes a single "compressed" value from the field and returns a list of "decompressed" values. The input value can be assumed valid, but not necessarily non-empty.

This method must be implemented by the subclass, and since the value may be empty, the implementation must be defensive.

The rationale behind "decompression" is that it is necessary to "split" the combined value of the form field into the values for each widget.

An example of this is how SplitDateTimeWidget turns a datetime value into a list with date and time split into two separate values:

Code
from django.forms import MultiWidget

class SplitDateTimeWidget(MultiWidget):

    # ...

    def decompress(self, value):
        if value:
            return [value.date(), value.time()]
        return [None, None]

Itu menyediakan beberapa konteks penyesuaian:

get_context(name, value, attrs)

Sebagai tambahan pada kunci 'widget' digambarkan dalam Widget.get_context(), MultiValueWidget menambahkan kunci widget['subwidgets'].

Ini dapat dilingkarkan dalam cetakan widget:

Django template
{% for subwidget in widget.subwidgets %}
    {% include widget.template_name with widget=subwidget %}
{% endfor %}

Here's an example widget which subclasses MultiWidget to display a date with the day, month, and year in different select boxes. This widget is intended to be used with a DateField rather than a MultiValueField, thus we have implemented value_from_datadict():

Code
from datetime import date
from django.forms import widgets

class DateSelectorWidget(widgets.MultiWidget):
    def __init__(self, attrs=None):
        # create choices for days, months, years
        # example below, the rest snipped for brevity.
        years = [(year, year) for year in (2011, 2012, 2013)]
        _widgets = (
            widgets.Select(attrs=attrs, choices=days),
            widgets.Select(attrs=attrs, choices=months),
            widgets.Select(attrs=attrs, choices=years),
        )
        super().__init__(_widgets, attrs)

    def decompress(self, value):
        if value:
            return [value.day, value.month, value.year]
        return [None, None, None]

    def value_from_datadict(self, data, files, name):
        datelist = [
            widget.value_from_datadict(data, files, name + '_%s' % i)
            for i, widget in enumerate(self.widgets)]
        try:
            D = date(
                day=int(datelist[0]),
                month=int(datelist[1]),
                year=int(datelist[2]),
            )
        except ValueError:
            return ''
        else:
            return str(D)

The constructor creates several Select widgets in a tuple. The super class uses this tuple to setup the widget.

The required method decompress() breaks up a datetime.date value into the day, month, and year values corresponding to each widget. Note how the method handles the case where value is None.

The default implementation of value_from_datadict() returns a list of values corresponding to each Widget. This is appropriate when using a MultiWidget with a MultiValueField, but since we want to use this widget with a DateField which takes a single value, we have overridden this method to combine the data of all the subwidgets into a datetime.date. The method extracts data from the POST dictionary and constructs and validates the date. If it is valid, we return the string, otherwise, we return an empty string which will cause form.is_valid to return False.

Widget pasang tetap

Django provides a representation of all the basic HTML widgets, plus some commonly used groups of widgets in the django.forms.widgets module, including the input of text, various checkboxes and selectors, uploading files, and handling of multi-valued input.

Widget menangani masukan dari teks

Widget ini membuat penggunaan dari unsur-unsur HTML input` dan ``textarea.

TextInput

class TextInput

  • input_type: 'text'

  • template_name: 'django/forms/widgets/text.html'

  • Membangun sebagai: <input type="text" ...>

NumberInput

class NumberInput

  • input_type: 'number'

  • template_name: 'django/forms/widgets/number.html'

  • Membangun sebagai: <input type="number" ...>

Beware that not all browsers support entering localized numbers in number input types. Django itself avoids using them for fields having their localize property set to True.

EmailInput

class EmailInput

  • input_type: 'email'

  • template_name: 'django/forms/widgets/email.html'

  • Membangun sebagai: <input type="email" ...>

URLInput

class URLInput

  • input_type: 'url'

  • template_name: 'django/forms/widgets/url.html'

  • Membangun sebagai: <input type="url" ...>

PasswordInput

class PasswordInput

  • input_type: 'password'

  • template_name: 'django/forms/widgets/password.html'

  • Membangun sebagai: <input type="password" ...>

Mengambil satu argumen pilihan:

render_value

Determines whether the widget will have a value filled in when the form is re-displayed after a validation error (default is False).

HiddenInput

class HiddenInput

  • input_type: 'hidden'

  • template_name: 'django/forms/widgets/hidden.html'

  • Dibangun sebagai: <input type="hidden" ...>

Note that there also is a MultipleHiddenInput widget that encapsulates a set of hidden input elements.

DateInput

class DateInput

  • input_type: 'text'

  • template_name: 'django/forms/widgets/date.html'

  • Membangun sebagai: <input type="text" ...>

Mengambil argumen sama seperti TextInput, dengan satu atau lebih argumen pilihan:

format

Bentuk dimana nilaiinisial bidang ini akan ditampilkan.

If no format argument is provided, the default format is the first format found in DATE_INPUT_FORMATS and respects Format localization.

DateTimeInput

class DateTimeInput

  • input_type: 'text'

  • template_name: 'django/forms/widgets/datetime.html'

  • Membangun sebagai: <input type="text" ...>

Mengambil argumen sama seperti TextInput, dengan satu atau lebih argumen pilihan:

format

Bentuk dimana nilaiinisial bidang ini akan ditampilkan.

If no format argument is provided, the default format is the first format found in DATETIME_INPUT_FORMATS and respects Format localization.

By default, the microseconds part of the time value is always set to 0. If microseconds are required, use a subclass with the supports_microseconds attribute set to True.

TimeInput

class TimeInput

  • input_type: 'text'

  • template_name: 'django/forms/widgets/time.html'

  • Membangun sebagai: <input type="text" ...>

Mengambil argumen sama seperti TextInput, dengan satu atau lebih argumen pilihan:

format

Bentuk dimana nilaiinisial bidang ini akan ditampilkan.

Jika tidak ada argumen format disediakan, bentuk awalan adalah bentuk pertama ditemukan dalam TIME_INPUT_FORMATS dan menghormati Format localization.

Untuk perlakuan dari mikro detik, lihat DateTimeInput.

Textarea

class Textarea

  • template_name: 'django/forms/widgets/textarea.html'

  • Membangun sebagai: <textarea>...</textarea>

Widget pemilih dan kotak centang

Widget ini membuat penggunaan dari unsur-unsur HTML <select>, <input type="checkbox">, dan <input type="radio">.

Widgets that render multiple choices have an option_template_name attribute that specifies the template used to render each choice. For example, for the Select widget, select_option.html renders the <option> for a <select>.

CheckboxInput

class CheckboxInput

  • input_type: 'checkbox'

  • template_name: 'django/forms/widgets/checkbox.html'

  • Membangun sebagai: <input type="checkbox" ...>

Mengambil satu argumen pilihan:

check_test

A callable that takes the value of the CheckboxInput and returns True if the checkbox should be checked for that value.

Select

class Select

  • template_name: 'django/forms/widgets/select.html'

  • option_template_name: 'django/forms/widgets/select_option.html'

  • Membangun sebagai: <select><option ...>...</select>

choices

This attribute is optional when the form field does not have a choices attribute. If it does, it will override anything you set here when the attribute is updated on the Field.

NullBooleanSelect

class NullBooleanSelect

  • template_name: 'django/forms/widgets/select.html'

  • option_template_name: 'django/forms/widgets/select_option.html'

Pilih widget dengan pilihan 'Tidak dikenal', 'Ya' dan 'Tidak'

SelectMultiple

class SelectMultiple

  • template_name: 'django/forms/widgets/select.html'

  • option_template_name: 'django/forms/widgets/select_option.html'

Mirip pada Select, tetai mengizinkan banyak pemilihan: <select multiple>...</select>

RadioSelect

class RadioSelect

  • template_name: 'django/forms/widgets/radio.html'

  • option_template_name: 'django/forms/widgets/radio_option.html'

Mirip pada Select, tetapi dibangun sebagai daftar daritombol radio dalam <li>:

Html
<ul>
  <li><input type="radio" name="..."></li>
  ...
</ul>

For more granular control over the generated markup, you can loop over the radio buttons in the template. Assuming a form myform with a field beatles that uses a RadioSelect as its widget:

Django template
{% for radio in myform.beatles %}
<div class="myradio">
    {{ radio }}
</div>
{% endfor %}

Ini akan membangkitkan HTML berikut:

Html
<div class="myradio">
    <label for="id_beatles_0"><input id="id_beatles_0" name="beatles" type="radio" value="john" required> John</label>
</div>
<div class="myradio">
    <label for="id_beatles_1"><input id="id_beatles_1" name="beatles" type="radio" value="paul" required> Paul</label>
</div>
<div class="myradio">
    <label for="id_beatles_2"><input id="id_beatles_2" name="beatles" type="radio" value="george" required> George</label>
</div>
<div class="myradio">
    <label for="id_beatles_3"><input id="id_beatles_3" name="beatles" type="radio" value="ringo" required> Ringo</label>
</div>

That included the <label> tags. To get more granular, you can use each radio button's tag, choice_label and id_for_label attributes. For example, this template...

Django template
{% for radio in myform.beatles %}
    <label for="{{ radio.id_for_label }}">
        {{ radio.choice_label }}
        <span class="radio">{{ radio.tag }}</span>
    </label>
{% endfor %}

...akan menghasilkan HTML berikut:

Html
<label for="id_beatles_0">
    John
    <span class="radio"><input id="id_beatles_0" name="beatles" type="radio" value="john" required></span>
</label>

<label for="id_beatles_1">
    Paul
    <span class="radio"><input id="id_beatles_1" name="beatles" type="radio" value="paul" required></span>
</label>

<label for="id_beatles_2">
    George
    <span class="radio"><input id="id_beatles_2" name="beatles" type="radio" value="george" required></span>
</label>

<label for="id_beatles_3">
    Ringo
    <span class="radio"><input id="id_beatles_3" name="beatles" type="radio" value="ringo" required></span>
</label>

If you decide not to loop over the radio buttons -- e.g., if your template simply includes {{ myform.beatles }} -- they'll be output in a <ul> with <li> tags, as above.

The outer <ul> container receives the id attribute of the widget, if defined, or BoundField.auto_id otherwise.

When looping over the radio buttons, the label and input tags include for and id attributes, respectively. Each radio button has an id_for_label attribute to output the element's ID.

CheckboxSelectMultiple

class CheckboxSelectMultiple

  • template_name: 'django/forms/widgets/checkbox_select.html'

  • option_template_name: 'django/forms/widgets/checkbox_option.html'

Mirip pada SelectMultiple, tetapi dibangun sebagai daftar dari kotak centang:

Html
<ul>
  <li><input type="checkbox" name="..." ></li>
  ...
</ul>

The outer <ul> container receives the id attribute of the widget, if defined, or BoundField.auto_id otherwise.

Like RadioSelect, you can loop over the individual checkboxes for the widget's choices. Unlike RadioSelect, the checkboxes won't include the required HTML attribute if the field is required because browser validation would require all checkboxes to be checked instead of at least one.

When looping over the checkboxes, the label and input tags include for and id attributes, respectively. Each checkbox has an id_for_label attribute to output the element's ID.

Widget unggah berkas

FileInput

class FileInput

  • template_name: 'django/forms/widgets/file.html'

  • Membangun sebagai: <input type="file" ...>

ClearableFileInput

class ClearableFileInput

  • template_name: 'django/forms/widgets/clearable_file_input.html'

  • Membangun sebagai: <input type="file" ...> dengan masukan kotak centang tambahan untuk membersihkan nilai bidang, jika bidang tidak diwajibkan dan mempunyai data inisial.

Widget campuran

MultipleHiddenInput

class MultipleHiddenInput

  • template_name: 'django/forms/widgets/multiple_hidden.html'

  • Membangun sebagai: banyak etiket <input type="hidden" ...>

A widget that handles multiple hidden widgets for fields that have a list of values.

choices

This attribute is optional when the form field does not have a choices attribute. If it does, it will override anything you set here when the attribute is updated on the Field.

SplitDateTimeWidget

class SplitDateTimeWidget

  • template_name: 'django/forms/widgets/splitdatetime.html'

Wrapper (using MultiWidget) around two widgets: DateInput for the date, and TimeInput for the time. Must be used with SplitDateTimeField rather than DateTimeField.

SplitDateTimeWidget mempunyai beberapa argumen pilihan:

date_format

Mirip ke DateInput.format

time_format

Mirip ke TimeInput.format

date_attrs
time_attrs

Similar to Widget.attrs. A dictionary containing HTML attributes to be set on the rendered DateInput and TimeInput widgets, respectively. If these attributes aren't set, Widget.attrs is used instead.

SplitHiddenDateTimeWidget

class SplitHiddenDateTimeWidget

  • template_name: 'django/forms/widgets/splithiddendatetime.html'

Mirip pada SplitDateTimeWidget, tetapi menggunakan HiddenInput untuk kedua tanggal dan waktu.

SelectDateWidget

class SelectDateWidget

  • template_name: 'django/forms/widgets/select_date.html'

Pembungkus disekitar tiga widget Select: satu untuk bulan, hari dan tahun.

Mengambil beberapa argumen pilihan:

years

An optional list/tuple of years to use in the "year" select box. The default is a list containing the current year and the next 9 years.

months

An optional dict of months to use in the "months" select box.

The keys of the dict correspond to the month number (1-indexed) and the values are the displayed months:

Code
MONTHS = {
    1:_('jan'), 2:_('feb'), 3:_('mar'), 4:_('apr'),
    5:_('may'), 6:_('jun'), 7:_('jul'), 8:_('aug'),
    9:_('sep'), 10:_('oct'), 11:_('nov'), 12:_('dec')
}
empty_label

Jika DateField tidak diwajibkan, SelectDateWidget akan memiliki pilihan kosong pada atas dari daftar (yaitu --- secara awalan). Anda dapat merubah tekas dari label ini dengan atribut empty_label. empty_label dapat berupa sebuah string, list, atau tuple. Ketika sebuah string digunakan, semua kotak-kotak pilihan akan setiapnya memiliki sebuah pilihan kosong dengan label ini. Jika empty_label adalah sebuah list atau tuple dari 3 unsur string, kotak-kotak pilihan akan memiliki label penyesuaian mereka sendiri. Label harus dalam urutan ini ('year_label', 'month_label', 'day_label').

Python
# A custom empty label with string
field1 = forms.DateField(widget=SelectDateWidget(empty_label="Nothing"))

# A custom empty label with tuple
field1 = forms.DateField(
    widget=SelectDateWidget(
        empty_label=("Choose Year", "Choose Month", "Choose Day"),
    ),
)
