Print First Character from Django QuerySet
I was attempting to make a directory listing of sorts earlier tonight and couldn't think up a clean solution. Some surfing on the world wide web offered up a quick template tag solution.
For example, say we have a list of objects (Person) from our app's view, [<Person: Doe>, <Person: Li>, <Person: Smith>, ...], and want to only print the first letter of their last name.
We can do this by first taking the string person.last_name and turning it into a list. Then, to snag just the first item from our newly formed list.
| Template Tag with Filter(s) | Rendered Output |
|---|---|
| {{ person.last_name }} | Doe |
| {{ person.last_name|make_list }} | ['D', 'o', 'e'] |
| {{ person.last_name|make_list|first }} | D |
Profit!
