大家好,我正在尝试对我的视图实施某种形式的访问控制。我的程序结构如下: 1个项目有一些以外键形式绑定到它的用户。我只希望允许参与其中的人查看此项目。但是问题是我用来查询模板的数据库的PK在我的URL中,无法访问项目的用户可以简单地更改url查询并获得对他们无法访问的项目的访问权限。
我遇到了django的user_passes_test方法装饰器,并认为这正是实现此用户访问控制所需要的。
这是我想出的一些代码:
我的观点:
@method_decorator(user_passes_test(project_check(id)),name ='dispatch')
class ProjectDetailView(CreateView):
##this is actually not relavant##
model = SalesNotation
fields = ['sales_notes']
exclude = ['notation_id']
template_name = 'rnd/projects.html'
context_object_name = 'form'
##this is actually not relavant##
def get_context_data(self, **kwargs):
id = self.kwargs['id']
context = super(ProjectDetailView, self).get_context_data(**kwargs)
context['projects'] = SalesProject.objects.filter(sales_project_id = id)
这是我的网址:
path('projects/<int:id>/', ProjectDetailView.as_view(), name = 'rnd-projects'),
这是我的项目模型:
class SalesProject(models.Model):
sales_project_id = models.AutoField(primary_key=True)
sales_project_name = models.CharField(max_length=100)
salesExtra = models.ManyToManyField('SalesExtra', blank=True)
这是我用来保存其他信息的扩展用户模型:
class SalesExtra(models.Model):
user = models.OneToOneField(User,on_delete=models.CASCADE)
user_type = models.TextField(max_length=500, choices= role)
contact = models.IntegerField()
email = models.TextField(max_length=30,default = 'your email here')
这是我使用的方法修饰器:
def project_check(user,id):
return SalesProject.objects.filter(sales_project_id=id).filter(salesExtra__user=user)
但是,当我在运行服务器时收到此错误时,似乎无法简单地从URL中传递PK:
@method_decorator(user_passes_test(project_check(id) , name='dispatch'))
TypeError: project_check() missing 1 required positional argument: 'id
任何帮助将不胜感激!

不能。但是您可以改用UserPassesTestMixin
:
from django.contrib.auth.mixins import UserPassesTestMixin
class ProjectDetailView(UserPassesTestMixin, CreateView):
##this is actually not relavant##
model = SalesNotation
fields = ['sales_notes']
exclude = ['notation_id']
template_name = 'rnd/projects.html'
context_object_name = 'form'
##this is actually not relavant##
def get_context_data(self, **kwargs):
id = self.kwargs['id']
context = super(ProjectDetailView, self).get_context_data(**kwargs)
context['projects'] = SalesProject.objects.filter(sales_project_id = id)
def test_func(self):
return SalesProject.objects.filter(sales_project_id=self.kwargs["id"]).filter(salesExtra__user=self.request.user)
请注意此处的test_func
进行检查。 self.kwargs["id"]
会给您id
。
