Comment:
Works for me:
{{{
>>> import pickle
>>> pickle.dumps(RatingDimension.objects.all())
ccopy_reg
_reconstructor
p0
(cdjango.db.models.query
QuerySet
p1
...
}}}
Two suggestions for providing bug reports:
1. Provide an example of the code that is failing. "Pickling" is a very
vague operation, and as I've demonstrated, it does work under some
circumstances. You need to give specific instructions for how to generate
a failure. Remember that Django has a fairly extensive test suite, and
there are lots of pickling tests. If there is a problem, it's more than
likely going to be in edge case usage.
2. An example is good, but a *minimal* example is better. Is the
RatingDimensionManager necessary to stimulate this problem? What about the
Meta? The __unicode__ call? I don't doubt that these are necessary for
your code, but they don't assist the debugging process.
Looking at your models, there's a good chance that this is a duplicate of
#12924. I'm going to close this ticket worksforme (because it does). If it
turns out that this isn't a duplicate of #12924, please reopen with a
minimal example and a sample of how to induce the error.
