全局名称'request'未定义：覆盖form_valid [英] global name 'request' is not defined: overriding form_valid

问题描述

我有一个UpdateView，我覆盖form_valid方法。由于某种原因，请求被显示为未被覆盖的方法中定义。这是完整的类：

  class UpdateTopic（UpdateView）：
 model = Post 
 slug_field =' pk'
 slug_url_kwarg ='pk'
 form_class = CommentForm 
 template_name =forums / update_topic.html
 
 def form_valid（self，form）：
 user = self.request.user 
 rep = self.request.user.player.get_rep_total 
 
＃保护系统免遭url输入攻击
如果用户== self.object .user或rep> = 2500：
 self.object = form.save（commit = False）
 self.object.updated_by = self.request.user 
 self.object.save（ ）
 messages.add_message（request，message.SUCCESS，< strong>成功：< / strong>）注释已成功编辑！）
 else：
 messages.add_message ，message.ERROR，< strong>失败：< / strong>您没有访问级别来编辑该帖子！）
  

问题是行 messages.add_message（request，message.SUCCESS，< strong> Success：< / strong>该评论已成功编辑！）
似乎请求的范围超出范围，为什么会这样做？有没有办法解决这个问题？

解决方案

应该是 self.request 而不是请求。

  messages.add_message（self。请求，message.ERROR，...）
  

I have an UpdateView which I am overriding the form_valid method. For some reason 'request' is shown as being not defined within the overridden method. Here is the full class:

 class UpdateTopic(UpdateView):
        model = Post
        slug_field = 'pk'
        slug_url_kwarg = 'pk'
        form_class = CommentForm
        template_name = "forums/update_topic.html"

        def form_valid(self, form): 
            user = self.request.user 
            rep = self.request.user.player.get_rep_total

            # protect the system against url input attacks
            if user == self.object.user or rep >=2500:
                self.object = form.save(commit=False)
                self.object.updated_by = self.request.user 
                self.object.save()
                messages.add_message(request, message.SUCCESS, "<strong>Success:</strong> The comment was edited successfully!")
            else:
                messages.add_message(request, message.ERROR, "<strong>Failed:</strong> You don't have the access level to edit that post!")

The problem is the line messages.add_message(request, message.SUCCESS, "<strong>Success:</strong> The comment was edited successfully!") It seems like the request is out of scope some how. Why is it doing this? Is there a way to get around this?

解决方案

It should be self.request and not request.

messages.add_message(self.request, message.ERROR, "...")
