Django template how to look up a dictionary value with a variable

Question

mydict = {\"key1\":\"value1\", \"key2\":\"value2\"}

The regular way to lookup a dictionary value in a Django template is {{ mydict.key1 }}

Answer 1

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 }}
