Oh yes... sorry about that.
I assumed that you will find picture for every query.
You can try this instead:
def index
@users= User.all
@pic = []
@users.each do |p|
@pic << Picture.where(:phrase_id => :route , :culture_id =>
p.culture_id).limit(1)
end
@pic.compact!
end
by calling compact! on the array, we will eliminate all nil object.
On another note, are you sure, this is what you want to do? If you have 100
users, it will fire 100 sql queries which is not good.
