I have this statement ids = athlete.leagues.select("league_id").map(&league_id)
getting this error Fixnum (expected Proc)"
Anyone know what is going on here?

long story.
What is it that you’re trying to do with this statement? The closest i can guess is the following:
ids = athlete.leagues.select{|league|league.id = league_id}.map(&:league_id)
But that just gives an array of league_ids the same as the one you started with.
Instead this worked. Not sure exactly why the other works and not select.
athlete.leagues.collect(&:league_id)
because ".select" returns only those elements that return true to an evaluation, while ".collect" returns the result of the block passed to every element. Have a look at the Enumerable and Array api pages.
