Comment (by Simon Charette):

 FWIW adjusting your descriptor to use `__dict__['field']` instead of
 `__dict__['_field']` should work just fine.


 {{{#!python
 class SomeModel(models.Model):
     """
     a contrived model field where we want a "field" that is stored
     in a "field" column, but we use @property getter/setters so
     we name the SomeModel class's attribute as "_field".
     """
     name = models.TextField(null=True)
     _field = models.TextField(name="field")

     @property
     def field(self):
         return self.__dict__['field'].upper()

     @field.setter
     def field(self, new_value):
         self.__dict__['field'] = new_value.lower()
 }}}

 I don't think we can change the assumption that `name` either set
 implicitly or explicitly through a parameter  the will be present in
 `__dict__` without breaking a lot of stuff.
