我的模板

{% extends "base.html" %}

{% load i18n %}   
{% load account %}   
{% load url from future %}

{% block title %}Log in{% endblock %}

{% block content_header %}Log in{% endblock %}

{% block main_content %}    
    {% if socialaccount.providers  %}    
    <p> 
       {% blocktrans with site.name as site_name %}
       Please sign in with your existing acounts through     
       {% endblocktrans %}

       <div class="socialaccount_ballot"> 
          <ul class="socialaccount_providers">
          {% include "socialaccount/snippets/provider_list.html" %}    
          </ul>

          <div class="login-or">{% trans 'or' %}</div>  
       </div>

       {% include "socialaccount/snippets/login_extra.html" %}

       {% blocktrans %}    
       <a href="{{ signup_url }}">sign up</a> for a {{site_name}} account and sign in below:
       {% endblocktrans %}
    </p>   
    {% endif %}         
{% endblock %}

Answer 1

您在以下位置定义了site_name：

{% blocktrans with site.name as site_name %}
    Please sign in with your existing acounts 
{% endblocktrans %}

你没有引用它。

但您在<：p>处引用了site_name

{% blocktrans %}
    <a href="{{ signup_url }}">sign up</a> for a {{site_name}} account and sign in below:
{% endblocktrans %}

您未在开始site_name代码时声明并定义blocktrans。

正如我从你的追溯中看到的，django没有抱怨，因此可能会从socialaccount/snippets/provider_list.html或socialaccount/snippets/login_extra.html发出错误。

Answer 2

仅{% endblock %}，而不是{% endblocktrans %}

是什么导致以下模板错误'无效的块标记：'blocktrans'，预期'elif'，'else'或'endif'？
