How to access class variable in Model class

rails-console, ruby-on-rails

Solution

Do this:

class Order < ActiveRecord::Base
   cattr_reader :test, :threshold
   self.test = 123
   self.threshold = {
     VIP: 500,
     PLATINUM: 20000
   }
end  

Order.test

Or I'd use constants:

class Order < ActiveRecord::Base
   TEST = 123
end

Order::TEST

Problem

I want to define the class variable `test`, `threshold` so that I can use `Order.test, Order.threshold` in my Rails app but I can not access the class variable when using the rails console I must misunderstand something, where's the problem? Thanks. ``` class Order < ActiveRecord::Base @@test=123 @@threshold = { VIP: 500, PLATINUM: 20000 } ``` Here is the `rails console` ``` irb(main):001:0> Order.class_variables => [:@@test, :@@threshold] irb(main):002:0> Order.test NoMethodError: private method `test' called for #<Class:0x007fe5a63ac738> ```
