class ImageFileDescriptor(FileDescriptor): (source)

Method __set__ Undocumented

Inherited from FileDescriptor:

Method __get__ Retrieve and caches the value from the datastore on the first lookup. Return the cached value.

Method	`__init__`	Undocumented
Instance Variable	`field`	Undocumented
Method	`_check_parent_chain`	Check if the field value can be fetched from a parent field already loaded in the instance. This can be done if the to-be fetched field is a primary key field.
