For those who haven't followed, I'll try to re-explain prior to showing example
code:
Currently, we can change the attrs declaratively without going through whatever
override/boilerplate.
In 2020, we can use custom elements, which means that we also need to change
the tag name.
We don't need special constructors because custom elements configures with
attrs, which are already available declaratively.
Now for some examples:
class YourForm(forms.ModelForm):
class Meta:
model = YourModel
widgets = dict(
birth_date=forms.TextInput(attrs={'type': 'date', 'max': max_date})
)
Victory ! We now have a native date field with a one-liner ! But what if we
want to change to a duet date picker ? You need to change the tag name from
"input" to "duet-tag-picker":
forms.TextInput(attrs={'type': 'date', 'max': max_date}, tag='duet-date-picker')
It seems the reason for being able to set attrs this way but not the tag name
too is because this was designed prior to the custom element W3C standard
that's now implemented in every browser.
