如何修复“从应用程序收到的不完整响应”

Question

我一定要疯了……

如果我有 48 行或更少行的 views.py 文件，当我向它发布数据时，我会看到

从应用程序收到不完整的响应

但是，如果我有 49 行或更多行，我会得到一个

NameError, 'request' 未定义

在第 31 和 49 行抛出，即使第 31/49 行为空。

有人能解释一下发生了什么吗？

顺便说一句，Django Admin - "Incomplete response received from application" 没有回答我的问题。

veiws.py:

from django.shortcuts import render
from django.shortcuts import render
from django.shortcuts import HttpResponse
from django.core.exceptions import *
from datetime import datetime
def remove_xss(chat, request):
    return chat
def find_urls(chat, request):
    new_chat = ' '.join([('<a href="{}">{}</a>'.format(word, word) if ('http://' in word or 'https://' in word) else word) for word in chat.split(' ')])
    return new_chat
def format_chat(chat, username, request):
    chat = remove_xss(chat, request)
    chat = find_urls(chat, request)
    request = request
    return "hi"
def chat_index(request):
    return render(request, 'chatroom.html')
def chat(request):
    if request.method == 'POST':
        chat = request.POST.get('textfield', None)
        if request.user.is_authenticated():
            u = request.user.username
            f_chat = format_chat(chat, u, request)
        else:
            return HttpResponse('You must be signed in to continue')
        with open('chats.txt', 'a') as chats: 
            chats.write(f_chat)    
    return render(request, 'chatroom.html')

urls.py:（工作（我认为））

from chat import views

from django.urls import path

urlpatterns = [
    path('/', views.chat_index),
    path('chat/', views.chat)
]

完整回溯：（当有 >=49 行时）

好的，对于任何来到这里的人，您所需要做的就是查看不同的文件。错误不必在您认为它所在的文件中。
