Class SelectDateWidget

A widget that splits date input into three <select> boxes.

Declaration

class SelectDateWidget(Widget)

This also serves as an example of a Widget that has more than one HTML
element and hence implements value_from_datadict.

▶ def __init__(self, attrs=None, years=None, months=None, empty_label=None) override
source link
This method overrides django.forms.widgets.Widget.__init__.
▶ def format_value(self, value) override
Return a dict containing the year, month, and day of the current value. Use dict instead of a datetime to allow invalid dates such as February 31 to display correctly.

This method overrides django.forms.widgets.Widget.format_value.
▶ def get_context(self, name, value, attrs) override
source link
This method overrides django.forms.widgets.Widget.get_context.
▶ def id_for_label(self, id_) override
inherited doc Return the HTML ID attribute of this Widget for use by a <label>, given the ID of the field. Return None if no ID is available.
source link
This method overrides django.forms.widgets.Widget.id_for_label.
```
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.
```
▶ def value_from_datadict(self, data, files, name) override
inherited doc Given a dictionary of data and this widget's name, return the value of this widget or None if it's not provided.
source link
This method overrides django.forms.widgets.Widget.value_from_datadict.
▶ def value_omitted_from_data(self, data, files, name) override

This method overrides django.forms.widgets.Widget.value_omitted_from_data.
