django - 继续收到 Reverse for 'password_reset_confirm' not found 错误。 'password_reset_confirm' 不是有效的 View 函数或模式名称

Question

嘿伙计们，我在我的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不知道为什么会这样这是我的 urls.py 代码:

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

完整回溯:

NoReverseMatch at /accounts/password_reset/
Reverse for 'password_reset_confirm' not found. 'password_reset_confirm' is not a valid view function or pattern name.

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"),
]

这是我用来覆盖默认模板的模板之一 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 %}

我知道为什么会发生这种情况，因为我在 url 中发送了 uidb 和 token ....

用于使用 GMAIL 发送电子邮件的我的 SMTP conf:

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'

罪魁祸首是 app_name = 'accounts'。这意味着 PasswordResetView 中定义的 success_url 指向名为 password_reset_done 的 View ，因此无法再找到它的 View 。 PasswordResetConfirmView 也会发生同样的情况。

您可以使用包含命名空间前缀的 View 名称覆盖它:

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'
            <b>success_url=reverse_lazy('accounts:password_reset_done')</b>
        ),
        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'
            <b>success_url=reverse_lazy('accounts:password_reset_complete')</b>
        ),
        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，你还应该在它前面加上命名空间，所以:

{% url '<b>account:</b>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 original template [GitHub]然后保存一个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'),
            <b>email_template_name='<i>path_to/template.html</i>'</b>
        ),
        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'),
]
