模板渲染時發生Django錯誤：找到NoReverseMatch

Question

以下代碼段引發錯誤。 我搜索了解決方案，但找不到與我的情況有關的任何內容。 任何幫助，將不勝感激。

#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'),

我需要在視圖中將電子郵件模板呈現為字符串。

#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)

以下是針對SO簡化的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 %}

錯誤回溯：

正如FoxMaSk所說，您應該替換：

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

與：

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

請注意網址中視圖名稱的單引號，這在Django 1.5+中是必需的（不確定您使用的是哪個版本）。

更重要的是，我相信錯誤就在這里：

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

呈現模板時，您沒有將uid或令牌傳遞到上下文中，這就是為什么您在回溯消息中看到這些變量的空值的原因：

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