Just a few thoughts here - I cant' tell if you resolved this or not.
First - a method block is an implicit begin/end block, so if you are
immediately inside a method definition, you can skip begin/end and just use
rescue.
def create_song
@song = Song.create(params[:song])
rescue Sequel::ValidationFailed
flash[:notice] = @song.errors.full_messages
end
Second, raise_on_save_failures likely needs a true or false assignment to
it, and I believe the default is true, so that line in your model is likely
a no-op.
self.raise_on_save_failure = true
Third, we don't see where the create_song method is being called, so it's
probably difficult for most of us to provide any valuable feedback in that
regard. I'm assuming you have a post route that handles it.
