editable=False and manipulator.save(data) not working together

[Matthew Flanagan]

(I accidentally sent this to the developers list before)

Hi,

In my model I have the field:


   created_by = meta.ForeignKey(
       User,
       verbose_name='created by',
       editable=False,
       blank=True,
       null=True
   )


and the module method below to create a "validated" object:

   def _module_create(address, prefix, description, maintainer,
customer, created_by):
       from django.utils.datastructures import MultiValueDict
       from django.models.ip import ipsupernetworks

       data = MultiValueDict({
           'address': [address],
           'prefix': [prefix],
           'description': [description],
           'maintainer': [maintainer.id],
           'customer': [customer.id],
           'created_by': [created_by.id],
           'changed_by': [created_by.id],
       })
       manipulator = ipsupernetworks.AddManipulator()
       errors = manipulator.get_validation_errors(data)
       if errors:
           return None, errors
       else:
           manipulator.do_html2python(data)
           obj = manipulator.save(data)
           return obj, errors

But when I call obj.get_created_by() on a newly created object i get
'None'. When I remove "editable=False" from the field definition it
works.

is this how it is meant to behave? I do not want to have this field in
the admin but still be able to set it in the method above. Is there
another way of doing it? I know i can call mymodule.MyModel(...) but
this doesn't validate the arguments as far as I can tell.
