Django 1.10中的某些URL没有反向匹配

Question

我正在Django 1.10中制作一个Web应用程序，并且遇到了一个令人讨厌的错误，我似乎无法解决。 在此项目中，有几个Django应用程序，其URL功能正常，并且似乎与新的Account应用程序具有相似的设置。 但是，此身份验证应用给我带来了麻烦。

此外， account/register URL可以成功运行，并将用户插入数据库。 我不确定为什么某些URL有效，而另一些无效。

这是错误：

NoReverseMatch at /account/login/
Reverse for 'dashboard' with arguments '()' and keyword arguments '{}' not found. 0 pattern(s) tried: []
Request Method: POST
Request URL:    http://localhost:8000/account/login/
Django Version: 1.10.6
Exception Type: NoReverseMatch
Exception Value:    
Reverse for 'dashboard' with arguments '()' and keyword arguments '{}' not found. 0 pattern(s) tried: []

我有以下目录结构：

项目的url.py：

from django.conf.urls import url, include
from django.contrib import admin
from django.conf import settings
from django.conf.urls.static import static

urlpatterns = [
    url(r'^admin/', admin.site.urls),
    url(r'^account/', include('account.urls', namespace='account')),
    url(r'^orders/', include('orders.urls', namespace='orders')),
    url(r'^shop/', include('shop.urls', namespace='shop')),
    url(r'^cart/', include('cart.urls', namespace='cart')),

]

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

帐户应用urls.py：

urlpatterns = [
    # url(r'^login/$', views.user_login, name='login'),
    url(r'^$', views.dashboard, name='dashboard'),

    url(r'^register/$', views.register, name='register'),
    url(r'^edit/$', views.edit, name='edit'),

    # login / logout urls
    url(r'^login/$', django_views.login, name='login'),
    url(r'^logout/$', django_views.logout, name='logout'),
    url(r'^logout-then-login/$', django_views.logout_then_login, name='logout_then_login'),

    # change password urls
    url(r'^password-change/$', django_views.password_change, name='password_change'),
    url(r'^password-change/done/$', django_views.password_change_done, name='password_change_done'),

    # restore password urls
    url(r'^password-reset/$', django_views.password_reset, name='password_reset'),
    url(r'^password-reset/done/$', django_views.password_reset_done, name='password_reset_done'),
    url(r'^password-reset/confirm/(?P<uidb64>[-\w]+)/(?P<token>[-\w]+)/$', django_views.password_reset_confirm, name='password_reset_confirm'),
    url(r'^password-reset/complete/$', django_views.password_reset_complete, name='password_reset_complete'),
]

登录模板：

{% extends "base.html" %}

{% block title %}Log-in{% endblock %}

{% block content %}
    <h1>Log-in</h1>
    {% if form.errors %}
        <p>Your username and password didn't match. Please try again.</p>
    {% else %}
        <p>Please, use the following form to log-in. If you don't have an account <a href="{% url "account:register" %}">register here</a></p>
    {% endif %}

    <div class="login-form">
        <form action="{% url "account:login" %}" method="post">
            {{ form.as_p }}
            {% csrf_token %}
            <input type="hidden" name="next" value="{{ next }}" />
            <p><input type="submit" value="Log-in"></p>
        </form>
        <p><a href="{% url "account:password_reset" %}">Forgotten your password?</a></p>
    </div>

    <div class="social">

    </div>
{% endblock %}

    return render(request, 'account/dashboard.html', {'section': 'dashboard'})

Answer 1

在某处（未显示的模板中），您完成了{% url "dashboard" %} ，但是该URL在帐户名称空间下。 因此，您需要执行{% url "account:dashboard" %} 。
