I don't like get() and catching exceptions. What I usually do is something
like this:
foo_list = Foo.objects.filter(x=x)
if (len(foo_list) == 1):
foo = foo_list[0]
And if I need else, I can assign None or whatever. The advantage in this
way is that you don't get an exception, and you deal with all numbers of
elements except 1, not only 0 (it can be 2 or 3 for example). And you don't
have to catch exceptions for multiple and does-not-exist. Many times I
don't need else, I just don't do anything if the number of elements
received is not 1.
