Django模板中带有空格的字典键 [英] dict keys with spaces in Django templates
本文介绍了Django模板中带有空格的字典键的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
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'}}
