python manage.py migrate
python manage.py create_instance_projects

Также для всех моделей созданы сериализаторы

Пример на проекте

class ProjectsSerializer(ModelSerializer):
    roles = RolesInProjectSerializer(many=True, source="rolesinproject_set")
    tools = ToolsInProjectSerializer(many=True, source="toolsinproject_set")
    tags = TagsSerializer(many=True)
    groups = GroupSerializer(many=True)

    class Meta:
        model = Project
        fields = [
            "project_type",
            "project_name",
            "core_idea",
            "description",
            "finish_date",

            "roles",
            "tags",
