Hi i follow djangogirls tutorial for learning django

in the tutorial they use

author = models.ForeignKey('auth.User', on_delete=models.CASCADE)

But they import nothing for auth.User Why? i see in many tutorials this code:

from django.contrib.auth.models import User

whats diffrent beetween calling without import and calling with import

Thanks.

There is no semantical difference. But importing things can result in trouble: if you have circular imports, then Python can not run the program. It is thus often used to fix circular imports. Furthermore both are usually not a good idea, since one can use another User model. – Willem Van Onsem
@WillemVanOnsem So the good way is calling without import? – user8354377
Yes, in model definitions only. It won't work in other code. – Daniel Roseman
Not per se, both have advantages. The main advantage of using imports is that IDEs understand this better, and thus in case one renames a model, then it is renamed in the reference as well. – Willem Van Onsem
@DanielRoseman Thanks for your help – user8354377

Its used to avoid running into a circular import situation,

But even better is using get_user_model() see here in the docs
