django-children-models-dependencies 1.2.1

django-children-models-dependencies provides tools to get the dependencies in a tree of django models

Purpose

This is a small app that allow to get the children of a base model, in an dependency order from the model with the less dependencies, to the model with the more dependencies, each model coming after its own dependencies

For example, for theses models:

class BaseModel(models.Model):
    class Meta:
        abstract = True

class ChildModel1(BaseModel):
    pass

class ChildModel2(BaseModel):
    link = models.ForeignKey('myapp.ChildModel3', on_delete=models.CASCADE)


class ChildModel3(BaseModel):
    pass

The order will be:

from django_children_models_dependencies.manager import ChildrenDependenciesManager

self.assertListEqual(ChildrenDependenciesManager.get_children_dependencies(BaseModel), [
    ChildModel1,  # first model without dependencies
    ChildModel3,  # dependency of ChildModel2, so it comes before
    ChildModel2,  # last one, which must come after its own dependencies
])
