Question

我有一个包含嵌套属性的form_for的视图文件。最近，我添加了一个select标签来更新列：form_for对象的tile。出于某种原因，这个新列不会在提交时更新，但嵌套属性可以正常工作。

知道我在这里做错了什么吗？

<%= form_for @user, :html => {:class => "center"} , remote:true do |f| %>

  #does not update the tile column in the user model. I want the tiles column to save a number between 1 to 10
  <%= f.select(:tiles, [*1..10]) %> 

  #updates the nested attribute ontology.classification successfully
  <%= f.fields_for :ontology do |ontology| %>
    <%= ontology.select :classification,options_for_select(Tiles::ONTOLOGY_KEYS, selected:ontology.object.classification)%>
 <%end%>        

<%end%>

在用户模型中，我使用的是强参数

private
  def user_params
    params.require(:user).permit(:name, :tiles)
  end

users表的架构如下：

  create_table "users", force: true do |t|
    t.string   "name"
    t.string   "auth"
    t.datetime "created_at"
    t.datetime "updated_at"
    t.integer  "tiles"
  end

添加params哈希：参数：

{"utf8"=>"✓", "user"=>{"tiles"=>"9", "ontology_attributes"=>{"classification"=>"P3", "id"=>"19"}, "things_attributes"=>{"0"=>{"uuid"=>"03F098C4-4FEB-4E44-B3AE-8B19B34E837D", "id"=>"58"}, "1"=>{"uuid"=>"92F3A722-4B54-4CF1-8EC9-465831D353B8", "id"=>"59"}, "2"=>{"uuid"=>"5BC5CFEF-3DD2-40B1-8113-2ABD5EA0570A", "id"=>"60"}}, "data_attributes_attributes"=>{"0"=>{"key"=>"$current_consumption", "id"=>"27"}, "1"=>{"key"=>"$power_consumption_deviation", "id"=>"28"}}}, "button"=>"", "id"=>"42"}

感谢您帮助我！

使用select_tag，form_for不起作用
