python - Django - NoReverseMatch 位于/accounts/password_reset/

Question

我正在尝试使用内置的 Django 密码重置。翻看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 %}

我相当确定我已经正确添加了这些 URL，并且 r'^password_reset/$' 页面正确加载，但是在输入我的电子邮件并单击“重置我的密码”之后，我收到以下错误:

NoReverseMatch at /accounts/password_reset/

我什至不确定这个错误是什么意思，所以我很难调试。通过查看文档，这似乎不是很难实现的功能，但我似乎无法让它工作。我在这里做错了什么？

问题来自您对帐户 url 使用 namespace 和 View 中使用的 Django 内置模板。在模板 registration/password_reset_email.html 中，您将看到:

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

但是，您的应用中不存在 url 名称 password_reset_confirm，因为您使用了命名空间“accounts”- url 变成了 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 模式创建您自己的 password_reset_email.html 版本，并将其传递给您的 View

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')
