I've got a weird problem which i can work around but want to understand!
Let's say that name = "small_logo"
This works -
@small_logo = @music_service.send("small_logo").build(file_hash)
and this works
@small_logo = @music_service.send("#{name}").build(file_hash)
but this *doesn't* work
@small_logo = @music_service.send(name).build(file_hash)
and neither does this
@small_logo = @music_service.send(name.to_s).build(file_hash)
In other words, a string is fine but a variable set to a string isn't, unless it's converted to a string inside #{ }.
Can anyone explain this to me? I don't know if it's connected to the attachment_fu 'build' method or if it's some general ruby weirdness.
thanks max
