不断收到“找不到‘password_reset_confirm’的反向错误”。 “password_reset_confirm”不是有效的视图函数或模式名称

Question

大家好，我在网络应用程序上执行此功能以重置密码时不断收到此错误 我不知道为什么会发生 这是我的

urls.py

代码：

from django.urls import path
from .views import *
from django.contrib.auth import views as auth_views

完整追溯：

NoReverseMatch at /accounts/password_reset/

app_name = 'accounts'

urlpatterns = [
    path('create-user/', registerview, name='register'),
    path('login/', loginview, name='login'),
    path('logout/', logoutview, name='logout'),

    path('password_reset/', auth_views.PasswordResetView.as_view(template_name='accounts/reset_password.html'), name="password_reset"),
    path('password_reset_done/', auth_views.PasswordResetDoneView.as_view(template_name='accounts/reset_password_sent.html'), name="password_reset_done"),
    path('password_reset/<uidb64>/<token>/', auth_views.PasswordResetConfirmView.as_view(template_name='accounts/reset_password_form.html'), name="password_reset_confirm"),
    path('password_reset_complete/', auth_views.PasswordResetCompleteView.as_view(template_name='accounts/reset_password_sucess.html'), name="password_reset_complete"),
]

这是我的模板之一，我用它来覆盖默认模板

reset_password.html

：

<h2>Introduza o email para mudar a sua password</h2>

<form method="POST">
    {% csrf_token %}
    {{ form }}
    <input type="submit" value="Enviar email de atualizacao de password">
</form>

另一个错误：

{% load i18n %}{% autoescape off %}
2   {% blocktranslate %}You're receiving this email because you requested a password reset for your user account at {{ site_name }}.{% endblocktranslate %}
3   
4   {% translate "Please go to the following page and choose a new password:" %}
5   {% block reset_link %}
6   {{ protocol }}://{{ domain }}{% url 'password_reset_confirm' uidb64=uid token=token %}
7   {% endblock %}
8   {% translate 'Your username, in case you’ve forgotten:' %} {{ user.get_username }}
9   
10  {% translate "Thanks for using our site!" %}
11  
12  {% blocktranslate %}The {{ site_name }} team{% endblocktranslate %}
13  
14  {% endautoescape %}

我不知道为什么会发生这种情况，因为我发送了 uidb 和 url 中的令牌....

我的 SMTP 配置，用于使用 GMAIL 发送电子邮件：

EMAIL_BACKEND = 'django.core.mail.backends.smtp.EmailBackend'
EMAIL_HOST = 'smtp.gmail.com'
EMAIL_PORT = 587
EMAIL_USE_TLS = True
EMAIL_HOST_USER = 'my_email'
EMAIL_HOST_PASSWORD = 'my_email_password'

罪魁祸首就是

app_name = 'accounts'

。这意味着在

success_url

中定义的

PasswordResetView

指向名为

password_reset_done

的视图，因此不再能找到它的视图。

PasswordResetConfirmView

也会发生同样的情况。

您可以使用包含命名空间前缀的视图名称来覆盖它：

from django.urls import path, reverse
from .views import *
from django.contrib.auth import views as auth_views

#    namespace ↓ (view names need to be prefixed with 'accounts:')
app_name = 'accounts'

urlpatterns = [
    path('create-user/', registerview, name='register'),
    path('login/', loginview, name='login'),
    path('logout/', logoutview, name='logout'),

    path(
        'password_reset/',
        auth_views.PasswordResetView.as_view(
            template_name='accounts/reset_password.html'
            success_url=reverse_lazy('accounts:password_reset_done')
        ),
        name='password_reset'
    ),
    path('password_reset_done/', auth_views.PasswordResetDoneView.as_view(template_name='accounts/reset_password_sent.html'), name='password_reset_done'),
    path(
        'password_reset/<uidb64>/<token>/',
        auth_views.PasswordResetConfirmView.as_view(
            template_name='accounts/reset_password_form.html'
            success_url=reverse_lazy('accounts:password_reset_complete')
        ),
        name='password_reset_confirm'
    ),
    path('password_reset_complete/', auth_views.PasswordResetCompleteView.as_view(template_name='accounts/reset_password_sucess.html'), name='password_reset_complete'),
]

在模板中，您还应该在其前面添加命名空间，因此：

{% url 'account:password_reset_confirm' uidb64=uid token=token %}

如果这是内置模板，您可以创建自己的模板，例如通过复制粘贴原始模板[GitHub]，然后保存新模板并指定该模板的路径：

from django.urls import path, reverse
from .views import *
from django.contrib.auth import views as auth_views

#    namespace ↓ (view names need to be prefixed with 'accounts:')
app_name = 'accounts'

urlpatterns = [
    path('create-user/', registerview, name='register'),
    path('login/', loginview, name='login'),
    path('logout/', logoutview, name='logout'),

    path(
        'password_reset/',
        auth_views.PasswordResetView.as_view(
            template_name='accounts/reset_password.html',
            success_url=reverse_lazy('accounts:password_reset_done'),
            email_template_name='path_to/template.html'
        ),
        name='password_reset'
    ),
    path('password_reset_done/', auth_views.PasswordResetDoneView.as_view(template_name='accounts/reset_password_sent.html'), name='password_reset_done'),
    path(
        'password_reset/<uidb64>/<token>/',
        auth_views.PasswordResetConfirmView.as_view(
            template_name='accounts/reset_password_form.html'
            success_url=reverse_lazy('accounts:password_reset_complete')
        ),
        name='password_reset_confirm'
    ),
    path('password_reset_complete/', auth_views.PasswordResetCompleteView.as_view(template_name='accounts/reset_password_sucess.html'), name='password_reset_complete'),
]
