Django: set select choices dynamically in Forms

The problem

Sometimes we could need to set dynamically the choices of a select box in our forms. To do this we wish to pass as parameter the list of tuples to use in our form instance.

A solution

Create this kind of form is easy. This is the code:

from django import forms form = MyCustomForm(my_choices=list_of_tuples) class MyCustomForm(forms.Form): def __init__(self, *args, **kwargs): choices = kwargs.pop('my_choices') super(MyCustomForm, self).__init__(*args, **kwargs) self.fields["my_field"] = forms.ChoiceField(choices=choices) other_field = forms.CharField()
