Python will use solve the diamond problem through MRO[1], so it all depends
on the order you in which you mix your classes.
class MyBaseView(BaseDetailView):
def get_context_data(self, *args, **kwargs):
context = super(MyBaseView, self).get_context_data(*args, **kwargs)
context['foo'] = 'MyView'
return context
class MixinA(object):
def get_context_data(self, *args, **kwargs):
context = super(MixinA, self).get_context_data(*args, **kwargs)
context['foo'] = 'MixinA'
return context
class MixinB(object):
def get_context_data(self, *args, **kwargs):
context = super(MixinB, self).get_context_data(*args, **kwargs)
context['foo'] = 'MixinB'
return context
class SomeView(MixinA, MixinB, MyBaseView):
pass
# ----
This is the correct solution. Try changing the order of the mixins in
SomeView to see the difference.
