以下是我在views.py中的帐户代码：

from django.http import HttpResponse, HttpResponseRedirect, Http404
from django.shortcuts import render, redirect, render_to_response
from .forms import RegisterForm
from django.urls import reverse


# Create your views here.
def register(response):
    if response.method == "POST":
        form = RegisterForm(response.POST)
        if form.is_valid():
            form.save() 
            return redirect('account')   
    else:
        form = RegisterForm()
    return render(response, 'users/register.html', {"form":form})

def account(request):
    return render_to_response('users/account.html')

下面是我的account.html代码：

{% extends 'talk/base.html' %}

{% block head %}
    <link rel="stylesheet" href="../../static/css/styles.css">
    <title>Home</title>
{% endblock %}

{% load crispy_forms_tags %}

{% block body %}
    <nav>
        <ul class="nav-bar">
            <li><a href="{% url 'index' %}" class="home-button">Home</a></li>
        </ul>
    </nav>
    <p class="welcome-login-text">
        Welcome back!
    </p>
{% endblock %}

{%extends'talk/base.html%}
{%block head%}
家
{%endblock%}
{%load crispy_forms_tags%}
{%block body%}




欢迎回来！

任何帮助都将不胜感激。当我将返回重定向（'account'）从views.py更改为返回重定向（'home'）时，它会工作，这意味着错误在account中，但我找不到它，开始失去希望…

事实上，问题在于

模板
中的标签这里您正在调用index
，但在您的URL中您将其命名为home
，路径（'home/'，v_talk.index，name='home'）
。因此，要么将url名称更改为索引，即路径（'home/'，v_talk.index，name='index'）
，要么将标记中的索引替换为home，即
作为错误状态
找不到“索引”的反向项索引“”不是有效的视图函数
或图案名称
您并没有在URL中设置路径，该URL具有name=index
，罪魁祸首在下面一行
    <li><a href="{% url 'index' %}" class="home-button">Home</a></li>


当您尝试直接转到该URL时会发生什么情况？这一点都不管用！真不敢相信我犯了这样的错误
    <li><a href="{% url 'index' %}" class="home-button">Home</a></li>
