Django Forms - Can the initial value of one field be dependant on another?

Question

Example, for this form:

>>> class CommentForm(forms.Form):
...     name = forms.CharField(initial='class')
...     action = forms.ChoiceField(...)

Can I have the choices in the action field be different depending on what is in the name field?

Answer 1

How about wrapping initial in a function or a lambda, so that the value of initial is deferred until form creation. Something like:

class CommentForm(forms.Form):
    name = forms.CharField(initial=lambda : self.action) # or more complex logic
    action = forms.ChoiceField(...)
