This allows you to add permissions for anonymous, logged in user, author ... in the url:
-By default `LDPPermissions` is used.
-Specific permissin classes can be developed to fit special needs.
-
-## anonymous_perms, user_perms, owner_perms, superuser_perms
-
-Those allow you to set permissions from your model's meta.
-
-You can give the following permission to them:
-
-* `view`
-* `add`
-* `change`
-* `control`
-* `delete`
-* `inherit`
-
-With inherit, Users can herit from Anons. Also Owners can herit from Users.
-
-Eg. with this model Anons can view, Auths can add & Owners can edit & delete.
-
-Note that `owner_perms` need a `owner_field` or a `owner_urlid_field` meta that point the field with owner user.

Django-Guardian is used by default to support object-level permissions. Custom permissions can be added to your model using this attribute. See the [Django-Guardian documentation](https://django-guardian.readthedocs.io/en/stable/userguide/assign.html) for more information.
-By default, no permission class is applied on your model, which means there will be no permission check. In other words, anyone will be able to run any kind of request, read and write, even without being authenticated.
+By default, no permission class is applied on your model, which means there will be no permission check. In other words, anyone will be able to run any kind of request, read and write, even without being authenticated. Superusers always have all permissions on all resources.
### Default Permission classes
-### Role based permissions
-### Custom permission classes
-This allows you to add permissions for anonymous, logged in user, author ... in the url:
-Specific permission classes can be developed to fit special needs.
+DjangoLDP comes with a set of permission classes that you can use for standard behaviour.
-```python
-from djangoldp.models import Model
+ * AuthenticatedOnly: Refuse access to anonymous users
+ * ReadOnly: Refuse access to any write request
+ * ReadAndCreate: Refuse access to any request changing an existing resource
+ * AnonymousReadOnly: Refuse access to anonymous users with any write request
+ * LDDPermissions: Give access based on the permissions in the database. For container requests (list and create), based on model level permissions. For all others, based on object level permissions. This permission class is associated with a filter that only renders objects on which the user has access.
+ * OwnerPermissions: Give access based on the owner of the object. This class must be used in conjonction with the Meta option `owner_field` or `owner_urlid_field`. This permission class is associated with a filter that only render objects of which the user is owner.
+ * InheritPermissions: Give access based on the permissions on a related model. This class must be used in conjonction with the Meta option `inherit_permission`, which value must be the name of the `ForeignKey` or `OneToOneField` pointing to the object bearing the permission classes. It also applies filter based on the related model.
-class Todo(Model):
- name = models.CharField(max_length=255)
- deadline = models.DateTimeField()
- user = models.ForeignKey(settings.AUTH_USER_MODEL)
+ Permission classes can be chained together in a list, or through the | and & operators. Chaining in a list is equivalent to using the & operator.
+```python
+class MyModel(models.Model):
+ author_user = models.ForeignKey(settings.AUTH_USER_MODEL)
+ related = models.ForeignKey(SomeOtherModel)
class Meta:
- owner_field = 'user' # can be nested, e.g. user__parent
+ permission_classes = [InheritPermissions, AuthenticatedOnly&(ReadOnly|OwnerPermissions|LDPPermissions)]
+ inherit_permissions = 'related
+ owner_field = 'author_user'
+ auto_author_field = 'profile'
+```
+
+### Role based permissions
+
+Permissions can also be defind through roles defined in the Meta option `permission_roles`. When set, DjangoLDP will automatically create groups and assigne permissions on these groups when the object is created. The author can also be added automatically using the option `add_author`. The permission class `LDPPermissions` must be applied in order for the data base permission to be taken into account.
+
+```python
+class Circle(Model):
+ name = models.CharField(max_length=255, blank=True)
+ owner = models.ForeignKey(settings.AUTH_USER_MODEL, related_name="owned_circles", on_delete=models.DO_NOTHING, null=True, blank=True)
+ members = models.ForeignKey(Group, related_name="circles", on_delete=models.SET_NULL, null=True, blank=True)
+ admins = models.ForeignKey(Group, related_name="admin_circles", on_delete=models.SET_NULL, null=True, blank=True)
+
+ class Meta(Model.Meta):
+ auto_author = 'owner'
+ permission_classes = [LDPPermissions]
+ permission_roles = {
+ 'members': {'perms': ['view'], 'add_author': True},
+ 'admins': {'perms': ['view', 'change', 'control'], 'add_author': True},
+ }
```
-You can also use owner_urlid_field to point to a field that holds the urlid of the owner instead of a foreignkey to a User object.
+### Custom permission classes
-Important note:
-If you need to give permissions to owner's object, don't forget to add auto_author in model's meta
+Custom classes can be defined to handle specific permission checks. These class must inherit `djangoldp.permissions.LDPBasePermissions` and can override the following method:
-Superuser's are by default configured to have all of the default DjangoLDP permissions
-* you can restrict their permissions globally by setting `DEFAULT_SUPERUSER_PERMS = []` in your server settings
-* you can change it on a per-model basis as described here. Please note that if you use a custom permissions class you will need to give superusers this permission explicitly, or use the `SuperUsersPermission` class on the model which will grant superusers all permissions
+* get_filter_backend: returns a Filter class to be applied on the queryset before rendering. You can also define `filter_backend` as a field of the class directly.
+* has_permission: called at the very begining of the request to check whether the user has permissions to call the specific HTTP method.
+* has_object_permission: called on object requests on the first access to the object to check whether the user has rights on the request object.
+* get_permissions: called on every single resource rendered to output the permissions of the user on that resource. This method should not access the database as it could severly affect performances.

### Improving Performance
On certain endpoints, you may find that you only need a subset of fields on a model, and serializing them all is expensive (e.g. if I only need the `name` and `id` of each group chat, then why serialize all of their members?). To optimise the fields serialized, you can pass a custom header in the request, `Accept-Model-Fields`, with a `list` value of desired fields e.g. `['@id', 'name']`

* AuthenticatedOnly: Refuse access to anonymous users
* ReadOnly: Refuse access to any write request
* ReadAndCreate: Refuse access to any request changing an existing resource
+ * CreateOnly: Refuse access to any request other than creation
* AnonymousReadOnly: Refuse access to anonymous users with any write request
* LDDPermissions: Give access based on the permissions in the database. For container requests (list and create), based on model level permissions. For all others, based on object level permissions. This permission class is associated with a filter that only renders objects on which the user has access.
* PublicPermission: Give access based on a public flag on the object. This class must be used in conjonction with the Meta option `public_field`. This permission class is associated with a filter that only render objects that have the public flag set.
* OwnerPermissions: Give access based on the owner of the object. This class must be used in conjonction with the Meta option `owner_field` or `owner_urlid_field`. This permission class is associated with a filter that only render objects of which the user is owner. When using a reverse ForeignKey or M2M field with no related_name specified, do not add the '_set' suffix in the `owner_field`.
+ * OwnerCreatePermission: Refuse the creation of resources which owner is different from the request user.
* InheritPermissions: Give access based on the permissions on a related model. This class must be used in conjonction with the Meta option `inherit_permission`, which value must be a list of names of the `ForeignKey` or `OneToOneField` pointing to the objects bearing the permission classes. It also applies filter based on the related model. If several fields are given, at least one must give permission for the permission to be granted.
Permission classes can be chained together in a list, or through the | and & operators. Chaining in a list is equivalent to using the & operator.
