Question

我有与之关联的产品和2个控制器。在一个（products_controller.rb）中，只有index和show方法。另一个（backoffice / products_controller.rb）具有所有CRUD方法。当我想在backoffice / products_controller.rb中使用create或destroy方法时，我收到一个错误消息，这些方法在products_controller.rb中不可用。方法索引并显示正常工作。

例如，我如何在backoffice / products_controller中使用Destroy方法

  def destroy
    @post.destroy
    respond_to do |format|
      format.js { render 'destroy', status: :destroy, location: @product }
      format.html { redirect_to admin_products_path, notice: 'Product was successfully destroyed.' }
      format.json { head :no_content }
    end
  end

以及我如何调用此方法（视图/后台/产品）：

<%= link_to (fa_icon "trash"), product,  method: :delete, data: { confirm: 'Are you sure?' }, class: "pull-right btn btn-outline-danger" %>

错误-The action 'destroy' could not be found for ProductsController

路线：

  scope '/admin' do
    resources :categories, controller: 'backoffice/categories', as: "admin_categories"
    resources :products, controller: 'backoffice/products', as: "admin_products"
  end

UPD 形式：

<div class="container main">

  <%= form_with(model: product, local: true) do |form| %>

  <div class="field">
  <%= form.collection_select(:category_id, Category.all, :id, :title, class:'form-control' ) %>
</div>

  <div class="field">
      <%= form.label :title %>
      <%= form.text_field :title, class: "form-control"%>
  </div>
  <div class="field">
    <%= form.label :description %>
    <%= form.text_area :description, class: "form-control"%>
  </div>
  <br>
  <div class="text-center actions">
    <%= form.submit 'Submit', class: "btn btn-dark" %>
  </div>
  <% end %>
</div>

如果查看生成的HTML，则会发现：

<%= link_to (fa_icon "trash"), product,  method: :delete, data: { confirm: 'Are you sure?' }, class: "pull-right btn btn-outline-danger" %>

...解析为ProductsController（类似products/1），而不是Backoffice::ProductsController（类似backoffice/products/1）。您可能想要做更多类似的事情：

<%= link_to (fa_icon "trash"), admin_product_path(product),  method: :delete, data: { confirm: 'Are you sure?' }, class: "pull-right btn btn-outline-danger" %>

在您的表单中，您需要执行以下操作：

<%= form_with(model: product, local: true, url: admin_products_path) do |form| %>

您可能不需要摆弄那个url位。参见the docs。
