Ruby on Rails

Thanks, Ray. Per your suggestion, this fixed it:

def moods
ms=Mymood.where('user_id=?',user_id)
if ms.empty?
[]
else
ms.collect{|mm| mm.mood}
end
end

But it seems strange to have to write another query in the middle of a
model. I'd have thought that the "has_many :mymoods" in the user model
would have been enough.

Whatever. It's working now. Thanks for your help!
