Hi there
I use a custom model field (inherited from `TextField`) which simply
returns its value as an "enhanced" `unicode` object.
Unfortunately, this will raise UnicodeErrors as MySQLdb apparently fails
recognizing those values as `unicode`. The comparision isn't very clever
there ;)
MySQLdb has a `use_unicode` flag, but I don't know how to implement it in
Django and I think this is a serious bug.
I've prepared a whole test case right here: https://github.com/domibarton
/django-mysql-unicode-error
I hope this is enough for a "proper" bug description.
Cheers
Domi
'''EDIT:''' It has NOTHING to do with my custom text field, this was just
an example. Basically Django (or MySQLdb) fails when writing non-`unicode`
objects (but `unicode`-inherited objects) values to a `TextField`. Proof
for that issue is right here:
