[Django]-Django Multiple inheritance with different tables

✅

the problem is because the primary field for both the models are id, and a table cannot have 2 columns based on same name, do this and it will solve your error

class Article(Piece):
    id = models.AutoField(primary_key=True)
    name= models.CharField(max_length=100)

class Book(Piece):
    book_id = models.AutoField(primary_key=True)
    book_name= models.CharField(max_length=100)

You should try calling init on subclasses, like:

class Monday(Book, Article):
    id = models.AutoField(primary_key=True)
    name= models.CharField(max_length=100)

    def __init__(self, *args, **kwargs):
        return super().__init__(*args, **kwargs)


class OtherDay(Book, Article):
    book_id = models.AutoField(primary_key=True)
    book_name= models.CharField(max_length=100)

    def __init__(self, *args, **kwargs):
        return super().__init__(*args, **kwargs)

This is because, as a Python class, the super() method will call the superclasses definition only one time, while the simple inheritance would call ini() for each superclass.
