It would be nice if you guys created a new method that would allow for OR
querysets to be returned.
Right now you can use <model>.objects.filter() in conjunction with the q()
method but this is limiting since you have to have all the ORs in a single
filter statement. If you where to chain another filter statement the two
would be ANDed.
It would be helpful to have another method that would OR the chained
results together. This is helpful when you have conditional cases and
need to build the queryset up.
Example:
Say i have an object I'm querying and the query looks like this so far:
query = <model>.objects.filter( (Q(id=2) & Q(state=1)) | (Q(id=3) &
(state = 2)) ... )
Now lets say I want to append another OR to the end of the query if the
current logged in user is and admin. Currently I would have to write a
conditional statement and duplicate the query in two places except the
query with the if user.is_admin would have some additional conditions.
It would be ideal if we could just append another statement with an OR to
the current query:
example : query.include( Q(id=8) & Q(state=3))
This would allow greater flexibility and prevent wet code.
