Localization of Django model float field in forms

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

Django provides a way to tell explicitly which fields should be localized. You just add 'localized_fields' to your Meta Model class.

class FormEditBuilding(forms.ModelForm):

class Meta:
    model = Building
    exclude = []
    localized_fields = ['apartments_sqm', 'offices_sqm']

Django-Docs: https://docs.djangoproject.com/en/5.0/topics/forms/modelforms/#enabling-localization-of-fields

My approach was:

settings.py

DECIMAL_SEPARATOR = ','
USE_THOUSAND_SEPARATOR = True

Form's __init__ function

def __init__(self, *args, **kwargs):
    super(YourForm, self).__init__(*args, **kwargs)
    self.fields['field'].localize = True
    self.fields['field'].widget.is_localized = True

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.
