Question

我在rails 4应用程序中使用带有Bootstrap_Form_for的Cocoon Gem。一切正常，我创建和更新所有字段都没有问题，除非我尝试更改已设置的布尔字段。

您将在下面找到我的代码，非常感谢所有帮助。

products_controller：

    def update
    respond_to do |format|
      if @product.update(product_params)
        format.html { redirect_to @product, notice: 'Product was successfully updated.' }
        format.json { render :show, status: :ok, location: @product }
      else
        format.html { render :edit }
        format.json { render json: @product.errors, status: :unprocessable_entity }
      end
    end
  end

categories_controller：

  def create
@category = Category.new(category_params)

respond_to do |format|
  if @category.save
    format.html { redirect_to hq_company_settings_path(:anchor => "productsTab"), notice: 'Category was successfully created.' }
    format.js { redirect_to hq_company_settings_path(:anchor => "productsTab") }
  else
    format.html { redirect_to hq_company_settings_path(:anchor => "productsTab") }
    format.json { render json: @category.errors, status: :unprocessable_entity }
  end
end

端

类别模型：

belongs_to :company
has_many :products

accepts_nested_attributes_for :products, reject_if: :all_blank, allow_destroy: true

形式：

<!-- Add Products Form -->
                    <div>
                        <%= bootstrap_form_for(@category) do |f| %>
                        <% if @category.errors.any? %>
                        <div id="error_explanation">
                            <h2><%= pluralize(@category.errors.count, "error") %> prohibited this category from being saved:</h2>
                            <ul>
                                <% @category.errors.full_messages.each do |message| %>
                                <li><%= message %></li>
                                <% end %>
                            </ul>

                                    <%= render 'product_fields', :f => product %>
                                    <% end %>
                                </fieldset>
                            </div>
                            <div class="links margin-top-40">

                        <% end %>   
                    </div>   <!-- End Form Wrapper -->

嵌套的Cocoon表格：

<div class="nested-fields">
<div class="col-lg-9">
      <div class="input-group margin-bottom-20">
       <span class="input-group-addon"><i class="fa fa-plus"></i></span>
       <%= f.text_field :name, hide_label: true, placeholder: 'Product Name' %>
    </div>
 </div>
 <div class="col-lg-3">
   <div class="input-group margin-bottom-20">
    <span class="input-group-addon"><i class="fa fa-money"></i></span>
    <%= f.text_field :price, hide_label: true, placeholder: 'Price' %>
 </div>
</div>

Answer 1

问题出现在为我的复选框提供了bootstrap开关的“NAME”属性。

删除

name: 'my-checkbox'

这

<%= f.form_group :tracking do %>
  <%= f.check_box :tracking, label: " Inventory Tracking", class: 'radio1 js-switch', name: 'my-checkbox', inline: true  %>

最终解决了我的问题。

Cocoon，Bootstrap_Form_For和PostgreSQL更新所有字段但布尔复选框
