A more simple version of https://djangosnippets.org/snippets/1688/, inheriting from SelectDateWidget
, overriding only the necessarily.
Usage example:
In models.py:
from django.db import models
from django.utils.translation import gettext_lazy as _
class MyModel(models.Model):
start = models.DateField(
_("Start date"),
)
end = models.DateField(
_("End date"),
)
class Meta:
verbose_name = _("My model")
In forms.py:
from django import forms
from .models import MyModel
from .widgets import MonthYearWidget
class MyModelForm(forms.ModelForm):
class Meta:
model = MyModel
exclude = []
widgets = {
"start": MonthYearWidget(),
"end": MonthYearWidget(last_day=True),
}
kwargs:
- last_day : if set to
True
, returns the last day of the month in the generated date.
