I have a list of dictionaries where each dict has a boolean entry. I want to display the items that are True
, along with the count of those items. I'm using the selectattr
filter, but it returns a generator, and calling |length
on it raise an error. How can I get the length of the items returned from selectattr
in Jinja?
my_list = [{foo=False, ...}, {foo=True, ...}, ...]
{{ my_list|selectattr('foo', 'equalto', True)|length }}
There is a list
filter that will transform a generator into a list. So:
{{ my_list|selectattr('foo')|list|length }}
