31701	Extend DeferredAttribute  & Remove unnecessary overriding of contrib_to_class () in FileField	Sultan	nobody	"The model fields use, by default, the descriptor **DeferredAttribute** to access and process (if necessary) the data associated with them. This type of data represents the actual data in db column. I prefer to call it a “field data”.

To access the field data in instance dict, **Field.attname** is used as a key.

In addition to the field data, some other model fields (for example, ForeignKey) also use a ""client data"" of the attribute, the processing of which is performed by a particular descriptor. Such a descriptor is usually assigned to a model using **Field.name**.

This enables us to process and present data in different ways: article.author returns a User object, and article.auther_id returns a User object pk.

This feature is not used in model.FileField. Then why use FileField.name instead of FileField.attname for FileDescriptor?

I think it would be better if FileDescriptor uses field.attname and continue working with the DeferredAttribute class."	Cleanup/optimization	new	Database layer (models, ORM)	3.1	Normal				Unreviewed	1	0	0	0	1	0
