I'm using the new RawSQL class with annotate suggested by the django
documentation. I noticed the second parameter the constructor takes is a
tuple. When I used it in my project, however, I got a 'tuple object does
not have attribute 'extend'' error. I looked at the trace back and source
code, and found that django is calling 'extend()' on that parameter, which
should not happen if the parameter is expected to be a tuple. I don't know
if anyone has seen the same thing here. If I'm making a mistake, I'd like
to know the correct use of RawSQL. Thanks a lot.
The example given in the django doc is:
qs.annotate(val=RawSQL("select col from sometable where othercol = %s",
(someparam,)))
But this usage gives me an error stated above.
