以下代码段引发错误。我搜索了解决方案，但找不到与我的方案有关的任何内容。任何帮助，将不胜感激。

#urls.py
url(r'^password/reset/confirm/(?P<uidb36>[0-9A-Za-z]+)\/(?P<token>.+)/$', 
    app_name.password_reset_confirm,name='auth_password_reset_confirm'),

我需要在我的视图中将电子邮件模板呈现为字符串。

#views.py
from django.template import Context, loader
t = loader.get_template('app_name/email.html')
message = t.render(Context({"domain":"foo.com","protocol":"https"}))
user.email_user(subject, message, settings.DEFAULT_FROM_EMAIL)

以下是为 SO 简化的 html 文件：

{% load i18n %}{% autoescape off %}
<html>
    <body>
        {% block reset_link %}<br />
            <a href="{{ protocol }}://{{ domain }}/accounts/password/reset/confirm/{{uid}}/{{token}}">{{ protocol }}://{{ domain }}/accounts/password/reset/confirm/{{uid}}/{{token}}</a>
            <br />
        {% endblock %}
        {% trans "Thanks for using our product!" %}<br /><br />
        {% blocktrans %}Regards, <br />{{ site_name }} team{% endblocktrans %}
    </body>
</html>
{% endautoescape %}

正如 FoxMaSk 所评论的，您应该替换：

{{ protocol }}://{{ domain }}/accounts/password/reset/confirm/{{uid}}/{{token}}

和：

{{ protocol }}://{{ domain }}{% url 'auth_password_reset_confirm' uid36=uid token=token %}

请注意 url 中视图名称周围的单引号，这在 Django 1.5+ 中是必需的（不确定您使用的是什么版本）。

更重要的是，我相信错误就在这里：

message = t.render(Context({"domain":"foo.com","protocol":"https"}))

渲染模板时，您没有将 uid 或令牌传递到上下文中，这就是为什么您在这些变量的回溯消息中看到空值的原因：

NoReverseMatch: Reverse for 'django.contrib.auth.views.password_reset_confirm' with arguments '()' and keyword arguments '{u'uidb36': '', u'token': ''}' not found.
