Django template how to look up a dictionary value with a variable
dictionary, django, python, templates
Solution
Write a custom template filter:
from django.template.defaulttags import register
...
@register.filter
def get_item(dictionary, key):
return dictionary.get(key)
(I use `.get` so that if the key is absent, it returns none. If you do `dictionary[key]` it will raise a `KeyError` then.)
usage:
{{ mydict|get_item:item.NAME }}
Problem
``` mydict = {"key1":"value1", "key2":"value2"} ``` The regular way to lookup a dictionary value in a Django template is `{{ mydict.key1 }}`, `{{ mydict.key2 }}`. What if the key is a loop variable? ie: ``` {% for item in list %} # where item has an attribute NAME {{ mydict.item.NAME }} # I want to look up mydict[item.NAME] {% endfor %} ``` `mydict.item.NAME` fails. How to fix this?
