我创建了一个问题来添加一个enum和class_methods
# app/models/concerns/addressable.rb
module Addressable
extend ActiveSupport::Concern
included do
enum address_province: {
Queen: 'Q',
Bear: 'B'
}
end
class_methods do
def options_for_cities
%w[a b]
end
def scream
'aaaaaaaaaaaaaaaaaa'
end
end
end
# app/models/order.rb
class Order < ApplicationRecord
include Addressable
end
但是，当我尝试在 中执行这些方法中的任何一个时Order，它们都不起作用。
Running via Spring preloader in process 3004
Loading development environment (Rails 5.1.2)
irb(main):001:0> Order.options_for_cities
NoMethodError: undefined method `options_for_cities' for Order (call 'Order.connection' to establish a connection):Class
Did you mean? options_for_with_status
from (irb):1
irb(main):002:0> Order.scream
NoMethodError: undefined method `scream' for Order (call 'Order.connection' to establish a connection):Class

看来您与现有的可寻址模块有冲突。尝试将您的模块名称更改为不同的名称。
