Re: form mixin for modelform ?

Thanks for your response James. I am not well familiar with the metaclasses, I do not really see how to do it. What do you think of adding the fields in the init this way? extra_fields = {'extra1': forms.CharField(required=False), 'extra2': forms.CharField(required=False)} class ModelFormA(forms

custom field for callable python object like class or function

Hi, Do you know a custom field for a callable python object like a Class or a function ? It could store it as a string in the DB: "module1.module2.class" or "module1.module2.function" With that string, it could load it as a real python object when you get it from the DB. For example, you c

Re: JSONField: which app to choose ?

Hi Matt, Correct, using either null=True or blank=True on the field works. However, I don't get it since I didn't click on "save", I just wanted to display the add page containing it. Why does it attempt to validate the field at this time and not wait for the form to be sent ? Maybe this is how
