Description (last modified by James Bennett)

Hello, I'm using Debian sid, python 2.4 (and 2.5), django 0.95.1, and mysql 5. The tables created have collation utf8-bin.
When I tried to open the admin zone, I got this error:

Traceback (most recent call last):
File "/var/lib/python-support/python2.4/django/core/handlers/" in get_response
  74. response = callback(request, *callback_args, **callback_kwargs)
File "/var/lib/python-support/python2.4/django/contrib/admin/views/" in _checklogin
  49. if request.user.is_authenticated() and request.user.is_staff:
File "/var/lib/python-support/python2.4/django/contrib/auth/" in get_user
  71. user_id = request.session[SESSION_KEY]
File "/var/lib/python-support/python2.4/django/contrib/sessions/" in __getitem__
  18. return self._session[key]
File "/var/lib/python-support/python2.4/django/contrib/sessions/" in _get_session
  57. self._session_cache = s.get_decoded()
File "/var/lib/python-support/python2.4/django/contrib/sessions/" in get_decoded
  61. encoded_data = base64.decodestring(self.session_data)

  TypeError at /admin/
  a2b_base64() argument 1 must be string or read-only character buffer, not array.array

I solved it changing the collation of the field session_data in the django_session table from utf8-bin to latin1_general_ci.
There is a bug using utf8-bin in that field.

Thank you.

I'm tentatively marking this as "worksforme" - as I'm not sure how the collation could be affecting anything (encoding yes, but collation?) I've also looked at all my django_session tables and they're all utf8 on a set up similar to yours (Sarge, MySQL5, python 2.4). I am however running the svn version and NOT 0.95

Can you provide more information about this and correct me if I'm wrong? (& do reopen it if I am).

Yesterday, I tried to do it again, with a new database, and it worked using utf-bin.
I don't know exactly where the problem is, but there was an error.
If it happen again, I'll try to post more information.
Thank you.

this error happens to me, too.
It is an error with the session module and not with the adminpage, since it happens with a generic view, too.
It's still in the svn-version I tried.
Switching to postgresql saved the problem for me.

LightLan - which svn version were you having the problem on? there were a lot of changes recently rolled in for MySQL in [4724], which should have helped fix this.

I used 4703.
I'll test it with the new one, once I got some time, rolling through the tutorial atm ;)

I'm going to reopen #2335 and mark this as a duplicate, because an anonymous comment on that ticket has information about what causes the problem.
