Question

In a Django template, I can join a list of strings via

{{ listOfStrings | join: ", " }}

What if I want to join a certain property of objects in the list. For instance, what if I have a list of users and want to join their full names?

{{ listOfUsers.get_full_name | join: ", " }}

afaik, you can’t do that with built in template tags, and certainly not filters. What you probably want is a custom tag that does

return ",".join([user.get_full_name for user in listOfUsers])
