Python: how to inherit from two classes?

Question

Hi everybody!

First of all I'm a python newbie.

I'm playing with Django and I'm trying to extend some classes.

Now I'm in this situation:

I have a new class

customBaseModelAdmin(admin.options.BaseModelAdmin):
    #override a method of BaseModelAdmin

and I want to write another class

customModelAdmin(customBaseModelAdmin):

that obviously inherits customBaseModelAdmin, but that has the same methods of the standard ModelAdmin. But, since the standard ModelAdmin inherits the standard BaseModelAdmin, how can I do?

I tried with the definition

class customModelAdmin(customBaseModelAdmin, admin.options.ModelAdmin):

but it doesn't work.

Do you have any suggestion?

Thanks,

Giovanni

Answer 1

Why not just subclass ModelAdmin for customBaseModelAdmin?

Answer 2

Just let customBaseModelAdmin inherit from ModelAdmin. You can still override the method from BaseModelAdmin.

But of course it could be that ModelAdmin also overrides this method. I would take a look at the source code of these classes to really know what is going on there.

Answer 3

You do it like this:

class customModelAdmin(customBaseModelAdmin):
    etc
