3037	Q(a=1, b=2) treated as Q(a=1) | Q(b=2)	Andrew McNabb <amcnabb@…>	nobody	"As far as I can tell from the documentation, arguments to a Q are anded together, e.g. Q(a=1, b=2) is equivalent to Q(a=1) & Q(b=2).  However, I am currently finding (in revision 4085) that Q(a=1, b=2) is instead equivalent to Q(a=1) | Q(b=2).  In this particular case, I am doing something like:

q1 = Q(a=1, b=2)

q2 = Q(a=3, b=4)

model.objects.filter(q1 | q2)

When I look at connection.queries, I find that there is no parenthesization at all, and all of the terms are combined with OR like ""a=1 OR b=2 OR a=3 OR b=4"" instead of ""(a=1 AND b=2) OR (a=3 AND b=4)"".

I made my description a little bit abstract for clarity, but I can post the exact queries if necessary.  Right now I'm working around the problem by doing something of the form:

q1 = Q(a=1) & Q(b=2)

etc., which gives the query I expected.  I hope this report is clear.  Let me know if you have any questions."	defect	closed	Database layer (models, ORM)	dev	normal	fixed	qs-rf-fixed		Accepted	0	0	0	0	0	0
