permissions

1、在model表中添加用户user

owner = models.ForeignKey('auth.User', related_name='snippets', on_delete=models.CASCADE)

2、在序列化表中添加如下关联信息

对应表

owner = serializers.ReadOnlyField(source='owner.username')

用户表

snippets = serializers.PrimaryKeyRelatedField(many=True, queryset=Snippet.objects.all())

3、添加permission文件

from rest_framework import permissions


class IsOwnerOrReadOnly(permissions.BasePermission):
    """
    Custom permission to only allow owners of an object to edit it.
    """

    def has_object_permission(self, request, view, obj):
        # Read permissions are allowed to any request,
        # so we'll always allow GET, HEAD or OPTIONS requests.
        if request.method in permissions.SAFE_METHODS:
            return True

        # Write permissions are only allowed to the owner of the snippet.
        return obj.owner == request.user

4、在views中添加访问权限

permission_classes = (permissions.IsAuthenticatedOrReadOnly,)

permission_classes = (permissions.IsAuthenticatedOrReadOnly,
                      IsOwnerOrReadOnly,)
