In Django templates, firstof or default?

Question

Do these two commands have the same functionality in Django templates?

{{ foo|default:"bar" }}

and

{% firstof foo "bar" %}

If these work in the same way, then what are the best practices? Use firstof only if we have more than 2 arguments, or always use firstof?

Answer 1

default can be considered a specialized case of firstof.

firstof outputs the first variable that is not False - Think of the or clause - it evaluates until any one of the objects evaluate to True and returns that.

It can be used to compare multiple values, whereas default is used for a specific object.

default outputs the specified default value if the object evaluates to False
