这是我的 urls.py
代码
from django.contrib import admin
from django.urls import include, path
from talk import views as v_talk
from users import views as v_users
urlpatterns = [
path('admin/', admin.site.urls),
path('home/', v_talk.index, name='home'),
path('register/', v_users.register, name='register'),
path('account/', v_users.account, name='account'),
path("", include("talk.urls")),
path('', include("django.contrib.auth.urls")),
]
这是我在 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')
这是我的 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 %}
任何帮助将不胜感激。当我将 return redirect('account') 从 views.py 更改为 return redirect('home') 它有效，这意味着错误在帐户中，但我找不到它并开始失去希望......
实际上问题出在模板 <a href="{% url 'index' %}" class="home-button">Home</a> 中的 a tag 中，您在这里调用 index ，但在您的 url 中，您将其命名为 home，path('home/', v_talk.index, name='home')。因此，要么将您的 url 名称更改为索引，即path('home/', v_talk.index, name='index') 或用 home 替换标签中的索引，即 <a href="{% url 'home' %}" class="home-button">Home</a>
作为错误状态
Reverse for 'index' not found. 'index' is not a valid view function
or pattern name.
您没有在具有 name=index 的网址中设置路径，罪魁祸首是以下行
<li><a href="{% url 'index' %}" class="home-button">Home</a></li>
