我有 3 个模型;报价单、项目和产品。
我的 quote/new.html.erb 设置为呈现包含项目表单的部分,并在该项目表单中呈现部分以选择产品。
错误:ActiveModel::MassAssignmentSecurity::Error in QuotesController#create "Can't mass-assign protected attributes: products"
(我在下面编辑了不相关的东西) Quote.rb
class Quote < ActiveRecord::Base
attr_accessible :items_attributes
has_many :items, :dependent => :destroy
accepts_nested_attributes_for :items
end
项目.rb
class Item < ActiveRecord::Base
attr_accessible :price, :product_attributes
belongs_to :quote
belongs_to :product
accepts_nested_attributes_for :product
end
产品.rb
class Product < ActiveRecord::Base
attr_accessible :name, :item_make
has_many :items
accepts_nested_attributes_for :items
end
新的.html.erb
<%= simple_nested_form_for @quote do |m| %>
<%= m.simple_fields_for :items, :html => { :multipart => true } do |quoteform| %>
<%= render "form", f: quoteform %>
<% end %>
<%= m.link_to_add "Add an item", :items %>
<%= m.button :submit %>
<% end %>
_form.html.erb
<%= f.simple_fields_for :products, :html => { :multipart => true } do |x| %>
<% render "layouts/styleselect", g: x %>
<% end %>
_styleselect.html.erb
<% g.hidden_field :item_make, :value => @item.make %>
<%= g.input :name, collection: Product.where(:item_make => 1), label: false, input_html: {:id=>"sst_style"} %>
所以基本上嵌套的形式是Quote->Item->Product,但是item属于product,这可能是导致问题的原因吗?我尝试将 product_attributes 或 products_attributes 添加到 item 模型和 quote 模型中,并与 accept_nested_attributes_for 产品相同。
任何帮助将不胜感激,谢谢。
