Django 私人频道 - if self.object. #(消费者：其中之一：

Question

我正在尝试建立一个频道。我不希望其他用户有权访问详细视图。问题是我可以让一个人可以访问它，但我不知道如何让消费者和卖家都可以访问它？

class Group(models.Model):

    consumer = models.ForeignKey(settings.AUTH_USER_MODEL, on_delete=models.CASCADE, related_name="", blank=True, null=True)

    name = models.CharField(max_length=10)

    seller = models.ForeignKey(settings.AUTH_USER_MODEL, on_delete=models.CASCADE, related_name="")

    ...

    def __str__(self):

        return self.name

#Detail channel

@method_decorator(login_required(login_url='/cooker/login'),name="dispatch")

class CheckoutDetail(generic.DetailView):

    ...

    

    def get(self,request,*args,**kwargs):

        self.object = self.get_object()

        if self.object.consumer or self.object.seller != request.user: #it's redirect me to home page

            return HttpResponseRedirect('/')    

        

        return super(CheckoutDetail, self).get(request,*args,**kwargs)

Answer 1

正确的逻辑是if not (request.user == self.object.consumer or request.user == self.object.seller):    return redirect(...)但我会将该逻辑重构为 中的函数object，例如def has_access(self, user):    return (self.consumer == user or self.seller == user)然后调用它，例如if not self.object.has_access(user=request.user):    # ...

Answer 2

如果我正确理解你的意思，你必须像这样改变这一行：    if self.object.consumer != request.user and self.object.seller != request.user:             return HttpResponseRedirect('/')
