Fixed #7190. Boolean fields now return bool values instead of 1 or 0. Thanks, Alex Gaynor.

-.. admonition:: MySQL users..
+.. versionchanged:: 1.2
- A boolean field in MySQL is stored as a ``TINYINT`` column with a value of
- either 0 or 1 (most databases have a proper ``BOOLEAN`` type instead). So,
- for MySQL, only, when a ``BooleanField`` is retrieved from the database
- and stored on a model attribute, it will have the values 1 or 0, rather
- than ``True`` or ``False``. Normally, this shouldn't be a problem, since
- Python guarantees that ``1 == True`` and ``0 == False`` are both true.
- Just be careful if you're writing something like ``obj is True`` when
- ``obj`` is a value from a boolean attribute on a model. If that model was
- constructed using the ``mysql`` backend, the "``is``" test will fail.
- Prefer an equality test (using "``==``") in cases like this.
+ In previous versions of Django when running under MySQL ``BooleanFields``
+ would return their data as ``ints``, instead of true ``bools``. See the
+ release notes for a complete description of the change.
