Whats wrong with this method_missing?

A coworker who shall remain nameless had this method missing implementation in a module that got mixed into the app helper. This tricked me up for longer then it should, mostly because I hadn't synced up in awhile and so assumed the problem was in changes I made. I don't know if it would break anything in production, as I never go that far - a whole bunch of failing tests stopped me before I got that far.

Do you see whats wrong?

Well ‘methodname’ is a Symbol, and a Symbol never matches a Regexp.

Depending on what you try to achieve

methodname.to_s =~ /^render/

will do.

Oh and BTW, the never-match hide that fact that

…
methodname[/^render_/]
…

would raise a NoMethodError.

So…you brought a good point that I hadn’t even realized. =) The main issue that I saw was that it didn’t call super, but you are right in that it should convert to string to compare to the regex. So now I’m not sure why its working…

it’s written in some cracked-out language ;)
