Localization of Django model float field in forms

Question

I'm trying to localize a model float field in django forms.

This way it's working:

super(....)
self.fields["field_name"] = forms.FloatField(localize=True)

However I don't want to define a new form field, instead I would like to add the localization to my existing model field. This way it isn't working:

super(....)
self.fields['field_name'].localize = True

Does anyone know where I'm going wrong with my approach?

Thanks, Jonas

Answer 1

The issue is that the form field does various bits of initialization when it is instantiated, and setting the localize attribute after that does not rerun that initialization. See the code.

You might be able to get most of what you want by additionally setting the is_localized attribute on the widget:

self.fields['field_name'].localize = True
self.fields['field_name'].widget.is_localized = True

but at this point you'd probably be better off re-declaring the field anyway.
