拥有并属于许多模型变量名称

Question

所以我使用rails 4并使用以下方法将我的用户成功链接到我的Products表：

users.rb的

  has_and_belongs_to_many :products
  accepts_nested_attributes_for :products
  # Setup accessible (or protected) attributes for your model
  attr_accessible :email, :password, :password_confirmation, :remember_me, :role_ids, :product_ids

products.rb

has_and_belongs_to_many :users

查看/ userse / _form.html.erb

<%= simple_form_for(@user) do |f| %>
<%= f.association :products, label: "Product Release Email", value_method: :id, :as => :check_boxes %>

但是我想更改变量名：产品到：productReleaseEmail我试过changint users.rb到

has_and_belongs_to_many :productReleaseEmail, :class_name => "product"

但我收到错误“未初始化的常量User :: product”。所以我假设我的一些参考文献错了。

Answer 1

将其资本化：

class_name: "Product"
