Converting values to Python objects
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
.. versionchanged:: 1.8
Historically, Django provided a metaclass called ``SubfieldBase`` which
always called :meth:`~Field.to_python` on assignment. This did not play
nicely with custom database transformations, aggregation, or values
queries, so it has been replaced with :meth:`~Field.from_db_value`.
If your custom :class:`~Field` class deals with data structures that are more
complex than strings, dates, integers, or floats, then you may need to override
:meth:`~Field.from_db_value` and :meth:`~Field.to_python`.
