ImageField with db_column results in KeyError in Admin Edit

Description

Hi,
I seem to have stumbled upon a bug with ImageField.

Here are the steps to reproduce :

  • define a model with an ImageField that has a db_column attribute that is different from his attribute name
  • add an object of this class using the admin
  • try to access the change_form of this object again and you should see a KeyError

If I understand correctly, the problem is located at line 136 of django/contrib/admin/view/main.py where we try to access self.original.dict[self.field.column], which doesn't exist.
My patch simply return self.original.dict[self.field.attname] instead.
Please note that this hasn't been extensively tested and I really don't have the needed time to add unit tests.

Verified the problem still exists. The patch above works as advertised, although I have only tested in a simple case.

I've verified manually that the newforms-admin has resolved this issue, but I'd rather see some tests to verify that it doesn't creep up again before I'd be comfortable calling this closed.

All of django/contrib/admin/view/main.py has been totally refactored since this ticket was opened and nobody has observed this in nearly 3 years. I haven't confirmed if it's an issue or not anymore but I presume somebody would have chimed in since 1.0 if there were problems with this. Feel free to reopen.
