The first release
This package may be used to make your Tastypie-based API faster with Pony ORM.
The package uses Djony (http://github.com/nnseva/djony) package to integrate Pony ORM (http://doc.ponyorm.com/) into the Django, and inherits Tastypie (http://django-tastypie.readthedocs.org/en/latest/) package using it's infrastructure to implement Pony-based API.
The preliminary tests show that the resulting API is faster 1-4 times comparing with Tastypie-native API based on Django ORM. Results very depend on number of objects got, using inheritance and especially impressive with One-To-Many reltionships.
Note that you need to install the djony package and include djony at the END (required) of INSTALLED_APPS.
- Django-style inheritance is not supported by Djony, so use underlining one-to-one relationship in the API declaration instead
- regex, week_day, and search filters are not supported yet
Compare the following API declarations:
Django-based (old-style):
from django.contrib.auth import models as auth_models
from tastypie.constants import ALL,ALL_WITH_RELATIONS
from tastypie import ModelResource
from tastypie import ToManyField, ToOneField
class PermissionResource(ModelResource):
class Meta:
queryset = auth_models.Permission.objects.all()
object_model = queryset.model
filtering = dict([(n,ALL_WITH_RELATIONS) for n in object_model._meta.get_all_field_names()])
resource_name = 'auth/permission'
class UserResource(ModelResource):
user_permissions = ToManyField(PermissionResource,'user_permissions',related_name='user_set',null=True)
class Meta:
queryset = auth_models.User.objects.all()
object_model = queryset.model
filtering = dict([(n,ALL_WITH_RELATIONS) for n in object_model._meta.get_all_field_names()])
resource_name = 'auth/user'Pony-based (new-style):
...
from django.contrib.auth import models as auth_models
from tastypie.constants import ALL,ALL_WITH_RELATIONS
from tastypie import ModelResource
from tastypie import ToManyField, ToOneField
from tastypie_djony.resources import DjonyResource
from tastypie_djony.fields import SetField
class PermissionResource(DjonyResource):
class Meta:
object_model = auth_models.Permission
filtering = dict([(n,ALL_WITH_RELATIONS) for n in object_model._meta.get_all_field_names()])
resource_name = 'auth/permission'
class UserResource(DjonyResource):
user_permissions = SetField(PermissionResource,'user_permissions',related_name='user_set',null=True)
class Meta:
object_model = auth_models.User
filtering = dict([(n,ALL_WITH_RELATIONS) for n in object_model._meta.get_all_field_names()])
resource_name = 'auth/user'Use DjonyResource instead of tastypie-native ModelResource.
Use SetField instead of the tastypie-native ToManyField. You can use tastypie-native ToOneField as before, without notable changes.
Use object_model instead of queryset member of the Meta class for the resource declaration as you can see in the example above.
