drf 修改权限组件的判断方式OR

原权限判断代码

    def check_permissions(self, request):
        """
        Check if the request should be permitted.
        Raises an appropriate exception if the request is not permitted.
        """
        for permission in self.get_permissions():
            if not permission.has_permission(request, self):
                self.permission_denied(
                    request,
                    message=getattr(permission, 'message', None),
                    code=getattr(permission, 'code', None)
                )

修改判断（后用OrPermissionAPIView代替APIView）

from rest_framework.views import APIView

class OrPermissionAPIView(APIView):
    def check_permissions(self, request):
        """
       重写check_permissions方法，把权限变成or
        """
        # 创建一个list存放没有通过权限的权限类
        no_permission_list = []
        for permission in self.get_permissions():
            if permission.has_permission(request, self):
                # 有一个通过即返回
                return
            else:
                no_permission_list.append(permission)
        else:
            self.permission_denied(
                request,
                message=getattr(no_permission_list[0], 'message', None),
                code=getattr(no_permission_list[0], 'code', None)
            )

视图

#走正常判断逻辑and
class OrderView(APIView):

    def get(self, request):
        print(request.user, request.auth)
        return Response({'status': 'OrderView'})

from ext.views import OrPermissionAPIView

#走or判断逻辑
class UserView(OrPermissionAPIView):
    def get(self, request):
        print(request.user, request.auth)
        return Response({'status': 'UserView'})
