django-seriously 0.4.0

Opinionated collection of Django and DRF tools that came in handy time and again.

… wait what? no seriously, why isn’t that part of Django/DRF?

Opinionated collection of Django and Django REST framework tools that came in handy time and again.

• AdminItemAction

  • Allow triggering context-aware custom admin operations in model list views.

• admin_navigation_link

  • Allow navigation from the admin list view to other related models via links.

• MinimalUser (abstract model)

  • Bare minimum user model ready for customization.

  • Removes the username and auxiliary fields like first_name and last_name.

  • Allow creating users without a valid password (unusable password)

  • Abstract since its highly recommended to subclass the user model anyway.

• ValidatedJSONField (model field)

  • validate the structure of JSON fields with Pydantic models.

• TokenAuthentication

  • When OAuth2 adds too much complexity, DRF’s TokenAuthentication is too simple, and django-rest-knox does not quite fit the permissioning.

  • No plain passwords in database (PBKDF2, i.e. hashed and salted)

  • Enabled for permission scoping

  • Easy (one-time-view) token creation in Django admin

• BaseModel (abstract model)

  • Reusable base model with automatic created_at, updated_at fields.

  • Primary key is a random UUID (uuid4).

  • Ensure validation logic (full_clean()) always runs, not just in a subset of cases.

• AppSettings

  • A settings container with defaults and string importing inspired by DRF’s APISettings

Usage

AdminItemAction

# admin.py
from django_seriously.utils.admin import AdminItemAction


class UserAdminAction(AdminItemAction[User]):
    model_cls = User
    actions = [
        ("reset_invitation", "Reset Invitation"),
    ]

    @classmethod
    def is_actionable(cls, obj: User, action: str) -> bool:
        # check whether action should be shown for this item
        if action == "reset_invitation":
            return is_user_resettable_check(obj) # your code
        return False

    def perform_action(self, obj: User, action: str) -> Any:
        # perform the action on the item
        if action == "reset_invitation":
            perform_your_resetting(obj)  # your code
            obj.save()


@admin.register(User)
class UserAdmin(ModelAdmin):
    # insert item actions into a list view column
    list_display = (..., "admin_actions")

    def admin_actions(self, obj: User):
        return UserAdminAction.action_markup(obj)

# urls.py
from django_seriously.utils.admin import AdminItemAction

urlpatterns = [
    ...
    # item actions must precede regular admin endpoints
    path("admin/", AdminItemAction.urls()),
    path("admin/", admin.site.urls),
]

admin_navigation_link

# admin.py
from django_seriously.utils.admin import admin_navigation_link

@admin.register(Article)
class ArticleAdmin(ModelAdmin):
    # insert item actions into a list view column
    list_display = ('id', "name", "author_link")

    def author_link(self, obj: Article):
        return admin_navigation_link(obj.author, obj.author.name)

TokenAuthentication

# settings.py
INSTALLED_APPS = [
    ...
    # only required if auth token is not extended by you
    'django_seriously.authtoken',
    ...
]

SERIOUSLY_SETTINGS = {
    "AUTH_TOKEN_SCOPES": ["test-scope", "test-scope2"]
}

# views.py
from django_seriously.authtoken.authentication import TokenAuthentication, TokenHasScope

class TestViewSet(viewsets.ModelViewSet):
    ...
    permission_classes = [TokenHasScope]
    authentication_classes = [TokenAuthentication]
    required_scopes = ['test-scope']

MinimalUser

# models.py
from django_seriously.minimaluser.models import MinimalAbstractUser
from django_seriously.utils.models import BaseModel

# BaseModel is optional but adds useful uuid, created_at, updated_at
class User(BaseModel, MinimalAbstractUser):
    pass

# admin.py
from django_seriously.minimaluser.admin import MinimalUserAdmin

@admin.register(User)
class UserAdmin(MinimalUserAdmin):
    pass
