如何在Django中解决NoReverseMatch

问题描述

伙计们，当我尝试登录Django Web应用程序时遇到此错误

位于/ login /的NoReverseMatch 找不到“ blog-home”的反向链接。 “ blog-home”不是有效的视图函数或模式名称。

这是应用程序的urls.py代码

from django.urls import path
from .views import (PostListView,PostCreateView,PostUpdateView,PostDetailView,PostDeleteView,UserPostListView)
from . import views

app_name = 'posts'

urlpatterns = [
    path('',PostListView.as_view(),name="blog-home"),path('user/<str:username>/',UserPostListView.as_view(),name="user-posts"),path('post/<int:pk>/',PostDetailView.as_view(),name="post-detail"),path('post/new/',PostCreateView.as_view(),name="post-create"),path('post/<int:pk>/update',PostUpdateView.as_view(),name="post-update"),path('post/<int:pk>/delete',PostDeleteView.as_view(),name="post-delete"),path('about/',views.about,name="blog-about"),]

这也是另一个名为用户的应用程序中的登录模板代码

{% extends "blog/base.html" %}
{% load crispy_forms_tags %}
{% block content %}
    <div class="content-section">
        <form method="POST">
            {% csrf_token %}
            <fieldset class="form-group">
                <legend class="border-bottom mb-4">Log In</legend>
                {{ form|crispy }}
            </fieldset>
            <div class="form-group">
                <button class="btn btn-outline-info" type="submit">Login</button>
                <small class="text-muted ml-2">
                    <a href="{% url 'password_reset' %}">Forgot Password?</a>
                </small>
            </div>
        </form>
        <div class="border-top pt-3">
            <small class="text-muted">
                Need An Account? <a class="ml-2" href="{% url 'register' %}">Sign Up</a>
            </small>
        </div>
    </div>
{% endblock %}

下面是项目urls.py

from django.contrib import admin
from django.contrib.auth import views as auth_views
from django.urls import path,include
from django.conf import settings
from django.conf.urls.static import static
from users import views as user_view

urlpatterns = [
    path('admin/',admin.site.urls),path('register/',user_view.register,name="register"),path('profile/',user_view.profile,name="profile"),path('groups/',include("groups.urls",namespace="groups")),path('login/',auth_views.LoginView.as_view(template_name='users/login.html'),name="login"),path('logout/',auth_views.LogoutView.as_view(template_name='users/logout.html'),name="logout"),path('password-reset/',auth_views.PasswordResetView.as_view(template_name='users/password_reset.html'),name="password_reset"),path('password-reset/done/',auth_views.PasswordResetDoneView.as_view(template_name='users/password_reset_done.html'),name="password_reset_done"),path('password-reset-confirm/<uidb64>/<token>/',auth_views.PasswordResetConfirmView.as_view(template_name='users/password_reset_confirm.html'),name="password_reset_confirm"),path('password-reset-complete/',auth_views.PasswordResetCompleteView.as_view(template_name='users/password_reset_complete.html'),name="password_reset_complete"),path('',include("blog.urls")),]

if settings.DEBUG:
    urlpatterns += static(settings.STATIC_URL,document_root=settings.STATIC_ROOT)
    urlpatterns += static(settings.MEDIA_URL,document_root=settings.MEDIA_ROOT)
