我的应用程序需要在用户的购物车中多次复制技能（来自技能索引）。所以我决定在提交相关表单，包括重复数和Skill的id时，触发skills_controller的add-to-cart方法。为此，我在技能控制器的强参数中添加了计数器。

不幸的是，我缺少正确设置表单的一些东西：提交时，它会触发create方法。这是代码：

routes.rb提取

  resources :skills, :path => "variables" do
    resources :values_lists
    member do
      post :add_to_cart
      get  :create_values_list
      get  :upload_values_list
      get  :remove_values_list
    end
    collection do
      get :index_all
    end
  end

Skills_controller.rb方法

  def add_to_cart
    @template_skill = Skill.find(params[:id])
    iterations = params[:skill][:counter].to_i
    until iterations == 0
      @skill = @template_skill.deep_clone include: [:translations, :values_lists]
      @skill.business_object_id = session[:cart_id]
      @skill.template_skill_id = @template_skill.id
      @skill.code = "#{@template_skill.code}-#{Time.now.strftime("%Y%m%d:%H%M%S")}-#{iterations}"
      @skill.is_template = false
      @skill.save
      iterations -= 1
    end

    @business_object = BusinessObject.find(session[:cart_id])
    redirect_to @business_object, notice: t('SkillAdded2BO') # 'Skill successfully added to business object'
  end

index.html.erb表格内容

  <tbody>
    <% @skills.each do |skill| %>
      <tr data-href="<%= url_for skill %>">
        <% if not session[:cart_id].nil? %>
          <td>
            <%= form_with model: @skill, :action => "add_to_cart", :method => :post, remote: false do |f| %>
            <%= f.text_field :counter, value: "1", class: "mat-input-element", autofocus: true %>
              <button type="submit" class="mat-icon-button mat-button-base mat-primary add-button" title="<%= t('AddToUsed') %>">
                <span class="fa fa-plus"></span>
              </button>
            <% end %>
          </td>
        <% end %>
        <td class="no-wrap"><%= skill.code %></td>
        <td><%= link_to skill.translated_name, skill %></td>
        <td><%= link_to translation_for(skill.parent.name_translations), skill.parent %></td>
        <td><%= skill.responsible.name %></td>
        <td><%= skill.updated_by %></td>
        <td class="text-right"><%= format_date(skill.updated_at) %></td>
      </tr>
    <% end %>
  </tbody>

非常感谢你的帮助！

根据此表单助手指南，您使用的语法不存在

form_with model: @model, action: :custom_action

因此，在这种情况下，您必须指定url参数 forform_with才能使其工作。

<%= form_with model: @skill, url: :add_to_cart_skill_path(@skill), method: :post, remote: false do |f| %>
