Model class

if you set model class as dependency (cache.set(key, value, depends_on=[SomeModel])), and change any instance of SomeModel, call bulk_create, update or delete to model’s queryset, key will be invalidated.

Model instance

if you set model instance as dependency (cache.set(key, value, depends_on=[some_instance])), and change this instance(including changing m2m fields), key will be invalidated.

Related manger

Let’s assume you have following models:

class Parent(models.Model):
    name = models.CharField(max_length=32)

class Child(models.Model):
    parent = models.ForeignKey(Parent)
    name = models.CharField(max_length=32)

some_parent = Parent.objects.get(id=42)

so, if you set related manager as a dependency (cache.set(key, value, depends_on=[some_parent.child_set])), and change any Child object with parent = some_parent, key will be invalidated.
