common models in django

Question

I am new in Django and I don't know how to deal with sharing models problem. For simplicity assume that we have two apps: A1, A2 and one model M1. Now I would like to A1 and A2 are using the same model M1. I probably can put M1 inside A1 and A2 but this is not good idea. How to deal with this ?

what do you mean be `using the same model` ? How are the relationship defined? Is it a foreign key, or a many to many, or do both contain the fields specified in `m1` ? — karthikr, Nov 11 '14 at 20:39
For example i have table User and i want to use it as model in django in A1 and A2. Should i define this model twice in A1 and A2 models.py file or do something else to achieve this ? — Dawid Skrzypczyński, Nov 11 '14 at 20:44
oh.. you just need to import from where it is defined. example `from import User` — karthikr, Nov 11 '14 at 20:48

define M1 in app A1 or A2 and use like this in another app models.py:

from A1.models import M1

Thanks this is some solution but when I will have 10 apps then i will have to remember where i define this model. Better solution would be some folder where i would put common models. – Dawid Skrzypczyński Nov 11 '14 at 21:06

@DawidSkrzypczyński yes , `common` directory is best choince. – Hasan Ramezani Nov 11 '14 at 21:09
But that common directory needs to be a django app or normal directory. Otherwise how will we make migrations. – Adarsh Trivedi Aug 09 '18 at 11:18
