python - 限制对仅拥有的内容 django 的访问

Question

我正在使用 django-tastypie 编写 API .我希望有两个自定义权限问题 django-guardian可以修复。

我有两个用户组 Clinicians 和 Patients。临床医生应该能够访问只属于他们的患者的对象，而患者应该只能访问他们自己创建的对象。

我的代码如下:

class UserResource(ModelResource):
    class Meta:
        queryset = User.objects.all()
        resource_name = 'auth/user'
        excludes = ['email', 'password', 'is_superuser']


class BlogPostResource(ModelResource):
    author = fields.ToOneField(UserResource, 'author', full=True)

    class Meta:
        queryset = BlogPost.objects.all()
        resource_name = 'posts'
        allowed_methods = ["get", "post"]
        # Add it here.
        authentication = BasicAuthentication()
        authorization = DjangoAuthorization()
        filtering = {
            'author': ALL_WITH_RELATIONS,
        }

如何使用权限来限制对此 BlogPostResource 的访问？

Answer 1

您可以通过自定义 Authorization 来实现这一点类，例如:

class CustomAuthorization(Authorization):
    def apply_limits(self, request, object_list):     
        ...
        clin_group = Group.objects.get(name='YOUR GROUP')
        if request and hasattr(request, 'user'):
            if clin_group in request.user.groups.all(): 
                 object_list = object_list.filter(user__in=request.user.patients.all()) # or however you stop clinician>patient relation
            else:
                 object_list = object_list.filter(user=request.user)
        return object_list
