导轨中的模型故障

Question

I have customer.rb

    class Customer < ActiveRecord::Base
    acts_as_authentic
    has_many :credit_cards
    has_many :telephones
    has_many :virtual_pays
end

telephone.rb

    class Telephone < ActiveRecord::Base
    belongs_to :customers
end

When I use rails console ad write Customer.all, i'll get all data from db table customers, but when i try to fetch all data include cutomer telephone i get error I write: customers.telephones.all, then i try Customer.Telephone.all, but how to correctly do this?

NameError: undefined local variable or method customers' for main:Object from (irb):6 from /home/pp/.rvm/gems/ruby-1.9.2-p290/gems/railties-3.0.9/lib/rails/commands/console.rb:44:in start' from /home/pp/.rvm/gems/ruby-1.9.2-p290/gems/railties-3.0.9/lib/rails/commands/console.rb:8:in start' from /home/pp/.rvm/gems/ruby-1.9.2-p290/gems/railties-3.0.9/lib/rails/commands.rb:23:in ' from script/rails:6:in require' from script/rails:6:in '

Also I correct write model?

在您的电话模型中，它应该是belongs_to：customer（单数）。
