[Health-dev] [bug #45350] Error message : "none type" object has no attribute "id" when father/mother name is not filled in birth certificate modu

[Roberto Novaes]

Follow-up Comment #1, bug #45350 (project health):

I have run onto the same problem. I do not think, though, that making father
or mother mandatory is a good solution, because it is very common to have
birth certificates without a father and, sometimes, without even a mother.
This can happen for many reasons: parents are unknown, abandoned child,
incomplete registration procedures, etc. I think the best solution would be to
treat the exception, something like:

def get_father(self, name):
    if (self.birth_certificate):
        try:
            return self.birth_certificate.father.id
        except SomeError:
            pass
