我有3个型号;报价,项目和产品。
我的quote / new.html.erb设置为渲染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 :: QuotesController中的错误#create “无法批量分配受保护的属性:产品”
(我在下面编辑了不相关的内容) Quote.rb
class Quote < ActiveRecord::Base
attr_accessible :items_attributes
has_many :items, :dependent => :destroy
accepts_nested_attributes_for :items
end
item.rb的
class Item < ActiveRecord::Base
attr_accessible :price, :product_attributes
belongs_to :quote
belongs_to :product
accepts_nested_attributes_for :product
end
Product.rb
class Product < ActiveRecord::Base
attr_accessible :name, :item_make
has_many :items
accepts_nested_attributes_for :items
end
new.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"} %>
所以基本上嵌套的表格是Quote-&gt; Item-&gt; Product,但是item属于产品,这可能导致问题?我尝试将product_attributes或products_attributes添加到项目模型和报价模型中,并将accept_nested_attributes_for产品添加到产品模型中。
任何帮助都将不胜感激,谢谢。

看起来你需要products
单数。
<%= f.simple_fields_for :product, :html => { :multipart => true } do |x| %>
<% render "layouts/styleselect", g: x %>
<% end %>
您目前有:
<%= f.simple_fields_for :products, :html => { :multipart => true } do |x| %>
