通过Django模板中的键访问字典 [英] Accessing dictionary by key in Django template

问题描述

我将一个字典从我的视图传递给一个模板。所以 {key1：value1，key2：value2} 被传入并循环通过键，值对很好，但是我没有找到一个优雅的解决方案，从视图中直接访问一个特定的键，比如说key1，例如bu json.items [key1]。我可以使用一些if / then语句，但我宁愿直接做一个方法？

这是html模板中的循环代码：

  {％for key，value in json.items％} 
< li> {{key}}  -  {{value}} < /锂> 
 {％endfor％} 
  

解决方案

Django模板语言支持查找字典键，如下所示：

  {{json.key1}} 
  

请参阅变量和查找。

模板语言不提供显示 json [key] ，其中 key 是一个变量。您可以编写一个模板过滤器来执行此操作，如这个堆栈溢出问题。

I'm passing a dictionary from my view to a template. So {"key1":"value1","key2":"value2"} is passed in and looping through key,value pairs is fine, however I've not found an elegant solution from access directly in the view from a specific key, say "key1" for example bu json.items["key1"]. I could use some if/then statements, but I'd rather do directly is there a way?

Here is looping code in the html template:

{% for key, value in json.items %} 
  <li>{{key}} - {{value}}</li>
 {% endfor %}

解决方案

The Django template language supports looking up dictionary keys as follows:

{{ json.key1 }}

See the template docs on variables and lookups.

The template language does not provide a way to display json[key], where key is a variable. You can write a template filter to do this, as suggested in the answers to this Stack Overflow question.
