Installation

Muffin-Admin should be installed using pip:

pip install muffin-admin

With SQLAlchemy Core support:

pip install muffin-admin[sqlalchemy]

With Peewee ORM support:

pip install muffin-admin[peewee]

Usage

Initialize the admin:

from muffin_admin import Plugin

admin = Plugin(**options)

Initialize admin handlers (example for Peewee ORM):

from muffin_admin import PWAdminHandler

 @admin.route
 class UserResource(PWAdminHandler):

     """Create Admin Resource for the User model."""

     class Meta:

         """Tune the resource."""

         # Peewee Model for the admin resource
         model = User

         # Filters
         filters = 'email', 'created', 'is_active', 'role'

         # Tune serialization/deserialization schemas
         schema_meta = {
             'load_only': ('password',),
             'dump_only': ('created',),
         }

         # Columns to show
         columns = 'id', 'email', 'is_active', 'role', 'created'

         # Custom Material-UI icon
         icon = 'People'

Connect admin to an Muffin application:

admin.setup(app, **options)

Authentication

Decorate an authentication function with admin.check_auth:

@admin.check_auth
async def auth(request):
    """Fake authorization method. Just checks for an auth token exists in request."""
    return request.headers.get('authorization')

@admin.get_identity
async def ident(request):
    """Get current user information."""
    pk = request.headers.get('authorization')
    user = User.select().where(User.id == pk).first()
    if user:
        return {"id": user.id, "fullName": user.email}

Implement a login handler for standart react-admin auth page:

@admin.login
async def login(request):
    """Login a user."""
    data = await request.data()
    user = User.select().where(
        User.email == data['username'], User.password == data['password']).first()
    return ResponseJSON(user and user.id)

Custom Actions

from muffin_admin import PWAdminHandler

 @admin.route
 class UserResource(PWAdminHandler):

     # ...

     @PWAdminHandler.action('users/disable', view='list')
     async def disable_users(self, request, resource=None):
         ids = request.query.getall('ids')
         # ...

     @PWAdminHandler.action('users/{id}/admin', view='show')
     async def mark_admin(self, request, resource=None):
         # ...
