How to avoid duplicate models in django project?

Question

i'm learning django so i've many questions, and one is how i can reuse a model? i mean the models live in the application folder, but some models are exactly the same between two differents applications. So should i rewrite the model every time that i write a new app?

Answer 1

Yes, this is wrong when you have the same names of yours apps You also can use abstract models

class CommonInfo(models.Model):
    name = models.CharField(max_length=100)
    age = models.PositiveIntegerField()

    class Meta:
        abstract = True

class Student(CommonInfo):
    home_group = models.CharField(max_length=5)

Answer 2

If your models are exactly the same in different applications, you're doing something wrong. Don't forget that an application is basically just a set of models, and you can use one application's models within another application just by importing them.

Can you give an example of two applications with exactly the same models?
