class SoftwareVersionAdmin(ModelAdmin):
    fields = (\"product\", \"version_number\", \"descrip         


        

Answer 1

This specific code did not work for me. I simply change it a little:

if obj: # obj is not None, so this is a change page
        #kwargs['exclude'] = ['owner']
        self.fields = ['id', 'family_name', 'status', 'owner']
    else: # obj is None, so this is an add page
        #kwargs['fields'] = ['id', 'family_name', 'status']
        self.fields = ['id', 'family_name', 'status']
    return super(YourAdmin, self).get_form(request, obj, **kwargs)
