Now redundant any anything >0.96, as form_for_*
methods now have a fields
attribute
formfield_callback
s are a bit difficult to use, here's a helper method to create a callback function to use with the form_for_instance
and form_for_model
methods.
Example usage:
person_callback = new_callback(exclude=['password', 'can_add_staff', 'is_staff'])
def form_for_person(person):
return form_for_instance(person, formfield_callback=person_callback)
1 2 3 4 5 6 7 8 9 10 11 | def new_callback(exclude=None, include=None):
"""
Create a form callback which excludes or only includes certain fields.
"""
def _callback(field, **kwargs):
if include and field.name not in include:
return None
if exclude and field.name in exclude:
return None
return field.formfield(**kwargs)
return _callback
