Django REST Framework - 自定义权限未评估

Question

我正在尝试在扩展viewsets.ModelViewSet 的类上设置自定义权限，但似乎我的权限没有被评估。这是我的观点:

from rest_framework import viewsets
from rest_framework.authentication import SessionAuthentication, BasicAuthentication
from rest_framework.permissions import IsAuthenticated

import models
import serializers
from permissions import IsAdminOrAuthenticatedReadOnly

class KPIViewSet(viewsets.ModelViewSet):
    '''
    API endpoint that allows KPI metadata to be viewed or edited
    '''

    authentication_classes = (BasicAuthentication,)
    permission_classes = (IsAdminOrAuthenticatedReadOnly,)

    queryset = models.KPI.objects.all()
    serializer_class = serializers.KPISerializer

这是我的权限类别:

from rest_framework.permissions import BasePermission, SAFE_METHODS

class IsAdminOrAuthenticatedReadOnly(BasePermission):
    def has_permissions(self, request, view):

        if request.method in SAFE_METHODS:
            return request.user and request.user.is_authenticated()

        return request.user and request.user.is_staff()

我遇到的问题是 IsAdminOrAuthenticatedReadOnly 似乎从未得到评估。我通过强制它始终返回“False”以及将 View 中的permission_classes 值切换为“IsAuthenticated”来测试这一点。在前一种情况下，对端点的请求返回，就好像没有身份验证要求一样。稍后，将按预期强制执行身份验证。

我缺少什么想法吗？

方法名称是 has_permission 而不是 has_permissions (no s) ;)
