Question

I have a case statement that goes a little something like this:

case @type
 when "normal"

 when "return"

 else
end

That works fine but I want to add in something like:

case @type
 when "normal"

 when "return"

 when @type length > 1, and contains no spaces

 else
end

Is that valid / safe?

Answer 1

if you aren’t matching against the value of @type then don’t include it right after the case statement, but rather in the when clauses:

case 
  when @type=="normal" then "blah"

  when @type=="return" then "blah blah"

  when (@type.length>1 and !@type.include?(' ')) then "blah blah blah"

  else 
end
