Django - NoReverseMatch 在 /accounts/password_reset/答案

【问题标题】：Django - NoReverseMatch at /accounts/password_reset/Django - NoReverseMatch 在 /accounts/password_reset/

【问题描述】：

我正在尝试使用内置的 Django 密码重置。查看Django docs，据我所知，它基本上只涉及向urls.py添加一些URL

urls.py：

urlpatterns = [
    url(r'^login/$', views.login_view, name='login'),
    url(r'^password_reset/$', auth_views.password_reset, {'post_reset_redirect' : '/accounts/password_reset_done/'}, name='password_reset'),
    url(r'^password_reset_done/$', auth_views.password_reset_done, name='password_reset_done'),
    url(r'^password_reset/(?P<uidb64>[0-9A-Za-z_\-]+)/(?P<token>[0-9A-Za-z]{1,13}-[0-9A-Za-z]{1,20})/$', auth_views.password_reset_confirm, {'post_reset_redirect' : '/accounts/password_done/'}, name='password_reset_confirm'),
    url(r'^password_done/$', auth_views.password_reset_complete, name='password_done'),
    url(r'^auth/$', views.login_auth, name='login_auth'),
    url(r'^register/$', views.register_user, name='register'),
    url(r'^logout/$', views.logout_user, name='logout'),
]

login.html:

{% extends "base.html" %}

{% block content %}

    <title>{% block title %} | Login{% endblock %}</title>

    <form action="/accounts/auth/" method="POST">
        <h2>Login</h2>
        {% if error_message %}<div class="formfielderrors">* {{ error_message }}</div>{% endif %}
        {% csrf_token %}
        <label for="username">Username: </label>
        <br>
        <input type="text" name="username" value="" id="username">
        <br><br>
        <label for="password">Password: </label>
        <br>
        <input type="password" name="password" value="" id="password">
        <br><br>
        <a href="/accounts/password_reset/">Forgot Password?</a>
        <br><br>
        <input type="submit" value="Login" class="greenButton">
    </form>

{% endblock content %}

我很确定我已正确添加了这些 URL，并且 r'^password_reset/$' 页面正确加载，但在输入我的电子邮件并单击“重置我的密码”后，我收到以下错误：

NoReverseMatch 在 /accounts/password_reset/

我不完全确定这个错误是什么意思，所以调试起来非常困难。通过查看文档，这似乎并不难实现，但我似乎无法让它工作。我在这里做错了什么？

【问题讨论】：

您需要发布错误的完整回溯。还要发布您的重置密码页面html，我确定这与您的表单网址有关。
将这两个都添加到问题中。
/accounts/password_reset/ 中的accounts 来自哪里？
在主要的urls.py 中，我包含accounts，如下所示：url(r'^accounts/', include('accounts.urls', namespace='accounts')),。帐户应用程序包含我所有基于用户的身份验证内容（登录、重置密码等）

标签： python django

【解决方案1】：

问题来自您对帐户 url 的命名空间和视图中使用的 Django 内置模板。在模板registration/password_reset_email.html 你会看到：

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

但是，URL 名称 password_reset_confirm 在您的应用中不存在，因为您使用了命名空间“accounts” - 网址改为 accounts:password_reset_confirm。

您可以考虑创建一个单独的文件来存储不使用“accounts”命名空间的 url。例如

# urls_django_auth.py
url_patterns = [
    url(r'^password_reset/$', auth_views.password_reset, ...),
    url(r'^password_reset_done/$', auth_views.password_reset_done, ...),
    ... other django auth views ...
]

# urls.py
url_patterns = [
    ....
    url(r'^accounts/', include('accounts.urls', namespace='accounts')),
    url(r'^accounts/', include('accounts.urls_django_auth')),  
]

或者您可以使用正确的 URL 模式创建自己的 password_reset_email.html 版本，并将其传递给您的视图

url(r'^password_reset/$', auth_views.password_reset, {
    'post_reset_redirect' : '/accounts/password_reset_done/',
    'email_template_name': '/your/own/password_reset_email.html'     
}, name='password_reset')

【讨论】：

我收到一个错误.../accounts/urls_django_auth.py'>' does not appear to have any patterns in it. If you see valid patterns in the file then the issue is probably caused by a circular import.
