I think there is some confusion in this conversation
first of all: When you do that
@users = User.find(:all)
@users will be one array of users objects, and if user object answer
to the method name you can do:
@users.each do |u| puts u.name end
and you will get all users names,
But if you have somthing like this:
@users = [{:name => "john"}, {:name => "miguel"}]
you cannot do :
@users.each do |u| puts u.name end
because {:name => "jonh"} is an hash and it do not respond to method
name, although you can get the name if you do this {:name => "jonh"}
[:name]
So summarizing it:
a = User.new :name => "foo"
a.name # WORKS
a = {:name => "foo"}
a.name # DO NOT WORK
a[:name] # WORK
I hope that helps you
