Attempt to append to unique_together tuple

[shangxiao]

Trying out django-compositekey on a legacy database created with inspectdb, it appears as though an attempt is made to append to the unique_together tuple:

...
File "/xxx/.virtualenvs/xxx/lib/python2.7/site-packages/compositekey/db/models/fields/multiplekey.py", line 71, in lazy_init
cls._meta.unique_together.append(names)
AttributeError: 'tuple' object has no attribute 'append'

PS: I'm trying this out with 1.7, but looking back through previous releases of Django, unique_together always has been a tuple?

Hi,
please try with django 1.5.
Django support 1.6 and 1.7 is working in progress.
Django 1.6 has changed the ORM join part.

Like I said, it appears to have always been a tuple, even with 1.5, thought you might like to know

Got it, thanks.
Can you post a simple test to replicate the issue?
I'll add in the test suite.

Now I remember, I wrote a couple of years ago in the wiki tha inspectdb is not supported yet.

Anyway, the append should be changed in a new tuple assignment
thanks for the feedback

I have the same issue in MySql, only doing something similar to this
id = db.MultiFieldPK("author", "name")
