Dynamically creating the related_name from META class

Question

Most of my Django models use the same User Mixin, because of this I would like to dynamically create the related_name for the field.

I would like it to be the class name where TestModel becomes test_models or maybe even a set name from the meta class on the main model.

I have looked at self__class__.__name__ but this give me the name of the User class.

Would it be possible to do something like below, if so how....

class User(models.Model):
    user = models.ForeignKey(USER, related_name=META.related_name)

    class Meta:
        abstract = True


class TestModel(User):
    title = models.CharField(max_length=80)

    class Meta:
        related_name = "test_model"

Answer 1

I think it might be sufficient to handle this like it is documented here.

# myapp/models.py
class User(models.Model):
    user = models.ForeignKey(
        USER, 
        related_name="%(app_label)s_%(class)s_related"
    )

    class Meta:
        abstract = True


class TestModel(User):
     title = models.CharField(max_length=80)

This way the related name would dynamically become myapp_testmodel_related. Of course you can tweak the name and simplify the pattern, if it is certain that the names can't clash between multiple apps.
