Why this code doesn't work? I see in debugger (PyCharm) that init line is executed but nothing more. I have tried to put there raise exception to be really sure and again nothing happend.
class polo(object):
def __init__(self):
super(polo, self).__init__()
self.po=1 <- this code is newer executed
class EprForm(forms.ModelForm, polo):
class Meta:
model = models.Epr
You use multiple inheritance so in general Python will look for methods in left-to-right order. So if your class do not have __init__ it'll look for it in ModelForm and that (only if not found) in polo. In your code the polo.__init__ is never called because ModelForm.__init__ is called.
To call the constructors of both base classes use explicit constructor call:
class EprForm(forms.ModelForm, polo):
def __init__(self, *args, **kwargs)
forms.ModelForm.__init__(self, *args, **kwargs) # Call the constructor of ModelForm
polo.__init__(self, *args, **kwargs) # Call the constructor of polo
class Meta:
model = models.Epr
