Migration to Django 1.4.1 : nothing about auth.message in Backward incompatibilities CHANGELOG.

[Stan]

Hi,

Maybe I missed something but in upgrading a project from Django 1.3.x to 1.4.1 I have encounter the following error when running my tests :

Problem installing fixture '/Users/stan/Dropbox/Projets/Aden/Publish-dj1.4/fab4/../fab4/parametrage/fixtures/tests/auth.json': Traceback (most recent call last):
  File "/Users/stan/src/venv-dj-1.4/lib/python2.6/site-packages/django/core/management/commands/loaddata.py", line 190, in handle
    for obj in objects:
  File "/Users/stan/src/venv-dj-1.4/lib/python2.6/site-packages/django/core/serializers/json.py", line 49, in Deserializer
    raise DeserializationError(e)
DeserializationError: ContentType matching query does not exist.


It appears that the contenttype table created in the test database (syncdb too I presume) does not contains anymore the following row :

+----+----------------------------------------+--------------+-------------------------------+
| id | name                                   | app_label    | model                         |
+----+----------------------------------------+--------------+-------------------------------+
|  4 | message                                | auth         | message                       |


(Running the tests in django 1.3 is just fine)

Because debugging fixtures is a real pain (It always end with pdb :-), maybe a note in Changelog or something could save time to a bunch of people ?

Cheers !

Stanislas.

Hi Stanislas,

Since the user message framework was deprecated in Django 1.2, its deprecation is documented in the 1.2 release notes:

https://docs.djangoproject.com/en/1.4/releases/1.2/#user-messages-api

The features deprecated in Django 1.2 and eventually removed in Django 1.4 are listed in the deprecation timeline:

https://docs.djangoproject.com/en/1.4/internals/deprecation/#id2

In the future, we're going to link more prominently to this deprecation timeline. Although it's mentioned in the very first paragraph of the release notes, it's often overlooked. Here's a preview of the 1.5 release notes:

https://docs.djangoproject.com/en/dev/releases/1.5/#backwards-incompatible-changes-in-1-5

Cheers,

I had missed that one :-)
 
Thanks.
