Django - {％if％}块中的模板标记 [英] Django -- Template tag in {% if %} block

问题描述

我有以下字典传递给一个渲染函数，其中源是字符串列表，标题是可能等于源中字符串之一的字符串：

  {'title'：title，'sources'：sources}）
  

在HTML模板中，我想完成以下几行：

  {％for source来源％} 
< tr> 
< td> {{source}}< / td> 
< td> 
 {％if title == {{source}}％} 
刚刚！ 
 {％endif％} 
< / td> 
< / tr> 
 {％endfor％} 
  

但是，以下文本块会导致错误：

  / admin / start / 
中的TemplateSyntaxError无法解析余数：'{{'from'{{' 
  

...与 {％if title == {{source}} ％} 以红色突出显示。

解决方案

您不应该使用双括号 {{}} 语法 if 或 ifequal 语句，你可以只需访问变量，就像在正常的python中一样：

  {％if title == source％} 
。 .. 
 {％endif％} 
  

I have the following dictionary passed to a render function, with sources being a list of strings and title being a string potentially equal to one of the strings in sources:

{'title':title, 'sources':sources})

In the HTML template I'd like to accomplish something among the lines of the following:

{% for source in sources %}
  <tr>
    <td>{{ source }}</td>
    <td>
      {% if title == {{ source }} %}
        Just now!
      {% endif %}
    </td>
  </tr>
{% endfor %}

However, the following block of text results in an error:

TemplateSyntaxError at /admin/start/
Could not parse the remainder: '{{' from '{{'

...with {% if title == {{ source }} %} being highlighted in red.

解决方案

You shouldn't use the double-bracket {{ }} syntax within if or ifequal statements, you can simply access the variable there like you would in normal python:

{% if title == source %}
   ...
{% endif %}
