Django模板中带有空格的字典键 [英] dict keys with spaces in Django templates

问题描述

我正在尝试在 HTML 模板中从我的 view.py 中显示字典，例如:

I am trying to present a dictionary from my view.py at the HTML template such as:

test = { 'works': True, 'this fails':False }

并在模板中:

这没有问题:

{{ test.works }}

但是在单词之间有空格的字典键(例如this failed")不起作用:

But a dictionary key that is having an empty space between words such as 'this fails' doesn't work:

{{ test.this fails }}

我收到此错误:

无法解析余数:'失败' from 'this failed'

Could not parse the remainder: ' fails' from 'this fails'

我怎样才能克服这个问题?我不是填充模型的人，所以我无法更改 dict 的键来删除空格.

How can I overcome this problem? I am not the one filling the models, so I can't change the keys of the dict to remove spaces.

推荐答案

你想要的过滤器类似于

The filter you want is something like

@register.filter(name='getkey')
def getkey(value, arg):
    return value[arg]

并与

{{test|getkey:'this works'}}
