restframework-serializer-permissions 0.0.1

permission based serializing for django restframework

restframework-serializer-permissions

Drop in replacement for Django Restframework Serializers to add permission based field serialization.

Installation

Install this module into your environment:

$ pip install restframework-serializer-permissions

Example

This example uses a ModelSerializer as described in DRF Docs

# import permissions from rest_framework
from rest_framework.permissions import AllowAny, IsAuthenticated

# import serializers from serializer_permissions instead of rest_framework
from serializer_permissions  import serializers

# import you models
from myproject.models import ShoppingItem, ShoppingList


class ShoppingItemSerializer(serializers.ModelSerializer):

    item_name = serializers.CharField()

    class Meta:
        # metaclass as described in drf docs
        model = ShoppingItem
        fields = ('item_name', )


class ShoppingListSerializer(serializers.ModelSerializer):

    # Allow all users to list name
    list_name = serializers.CharField(permission_classes=(AllowAny, ))

    # Only allow authenticated users to retrieve the comment
    list_comment = serializers.CharField(permissions=(IsAuthenticated, ))

    # show owner only, when the current user has 'auth.view_user' permission
    owner = serializers.CharField(permissions=('auth.view_user', ), hide=True)

    # serializer which is only available, when the user is authenticated
    items = ShoppingItemSerializer(many=True, permissions=(IsAuthenticated, ), hide=True)

    class Meta:
        # metaclass as described in drf docs
        model = ShoppingItem
        fields = ('list_name', 'list_comment', 'owner', 'items', )

You can also define your own permissions classes as described in the DRF documentation and specify multiple rpermission_classes and rpermissions on a field or serializer: all provided permissions must be satisfied for the visitor to retrieve the given field.
