That ternary statement is incorrect formed. You'll also need to add
parentheses around the statement; otherwise Haml will start by trying to
concatenate true/false onto the title, resulting in a TypeError.
A correct version might be:
%title= 'Site Name :: ' + (action_name == "index" ? "Index" : "")
The titleized form of "index" will always be "Index", so I'm not sure why
that just isn't written explicitly... maybe you just want something like:
%title~ "Site Name :: #{action_name.titleize}"
Either way it doesn't make much sense to me, but you'll need parentheses and
the third part of the ternary operator (the "else" clause)
Best,
