Django Multiple ForeignKey and same related name

Question

I want to use user foreignkey to many models. I can't use this type of method. Is any possible way to give common name to all foreignkey. I want to access x.created or x.updated in every template.

class Model_one(models.Model):
    --
    --
    created = models.ForeignKey(User,related_name="created")
    updated = models.ForeignKey(User,related_name="updated")


class Model_two(models.Model):
    --
    --
    created = models.ForeignKey(User,related_name="created")
    updated = models.ForeignKey(User,related_name="updated")


class Model_three(models.Model):
    --
    --
    created = models.ForeignKey(User,related_name="created")
    updated = models.ForeignKey(User,related_name="updated")

Answer 1

To generalize your approach you could do something like that:

class BaseModel(models.Model):
    created = models.ForeignKey(User,related_name="created_%(class)s_objects")
    updated = models.ForeignKey(User,related_name="updated_%(class)s_objects")

    class Meta:
        abstract = True


class ModelOne(BaseModel):
    # your model one fields


class ModelTwo(BaseModel):
    # your model two fields

With this approach you

• don't need to define the same fields on all models explicitly because you inherit from BaseModel.

• The special syntax automatically creates backward-relations with the right class names. Therefore user.created_modelone_objects.all() will give you all the objects an user has created.
