How does a field pass attributes to a widget? I have approximately
this
class fooForm(forms.Form):
x_choice=myForms.xField(widget=myWidgets.xWidget)
where myWidgets.xWidget is a subclass of RadioSelect so it has a
required argument like "choices=[('a','1'), ('b','a')]" (this is
generated dynamically so I can't build it in to xWidget). Where in
the Django code base does that information get passed?
The examples I've studied don't seem to me to show xField being
written to pass it explicitly but they do make a super() call, so I
expect it is done there. I see in the render code for the widget
references to the variable self.choices, so it is getting remembered
by the widget in that way. However, I've struggled with the Django
source and I can't make out how it is passed. I'd be very grateful if
someone could help me find it.
