我的Django模板使用if怎么了？ [英] What is wrong with my Django templating use of if's?

问题描述

$ $ $ $ $ $ $ $ $ $ $ $ $ $ $％$ $ $ $ $ $ $ $ $ $ $ 右键单击编辑。
href ={％if：不在url.url％} http：// {％endif％} {{url.url}}> {{url.url}}< / a> ;
< span class =deleteid =URL _ {{url.id}}>& amp; amp;＃10008;< / span> &安培; NBSP;
{％endfor％}

启发式用于预先添加部分或完整的网址，如google.com，假设有时人们会粘贴完整的浏览器网址，有时候人们会输入google.com，从不输入'​​http：//'。

模板引擎抱怨{％if：not in url.url％}是无效的语法。这里有什么正确的语法/方法？

解决方案

如何为此使用过滤器：

  href ={{ulr.url | urlize}}
  

请记住在此之前检查以建立自己的（查找urlize）：

我认为一个更好的方法是将URL保存为管理员中的绝对URL，并在显示链接时显示 http：// ...

{% for url in urls %}
    <a id="URL_url_{{ url.id }}" class="edit_rightclick"
      title="RIGHT click to edit."
      href="{% if ":" not in url.url %}http://{% endif %}{{ url.url }}">{{ url.url }}</a>
    <span class="delete" id="URL_{{ url.id }}">&amp;#10008;</span> &nbsp;
{% endfor %}

The heuristic is intended to prepend the value of a partial or complete URL like google.com, under the assumption that sometimes people will paste a full browser URL, and sometimes people will type out google.com and never type 'http://'.

The templating engine is complaining that '{% if ":" not in url.url %}' is invalid syntax. What is the correct syntax / approach here?

解决方案

What about using a filter for this:

href="{{ ulr.url|urlize }}"

Remember to check here before to build your own (look for urlize): https://docs.djangoproject.com/en/dev/ref/templates/builtins/

I think a better approach would be to the save the URLs as absolute ones within the admin and strip "http://" when showing the link...
