How to prevent short-circuit evaluation?
How about something like:
if all([form1.is_valid(), form2.is_valid()]): ...In a general case, a list-comprehension could be used so the results are calculated up front (as opposed to a generator expression which is commonly used in this context). e.g.:
if all([ form.is_valid() for form in (form1,form2) ]) This will scale up nicely to an arbitrary number of conditions as well ... The only catch is that they all need to be connected by "and" as opposed to if foo and bar or baz: ....
(for a non-short circuiting or, you could use any instead of all).
You can simply use the binary & operator, which will do a non-short-circuit logical AND on bools.
if form1.is_valid() & form2.is_valid(): ...
You can use the Infix operators (ActiveState Python recipe) for defining your own Boolean operators:
aand = Infix(lambda x,y: bool(x) and bool(y))1 |aand| 2 # Will return `True` instead of `1`
