突然间，我的 Rails 应用程序表现得很奇怪。如果我在编辑页面上附加图像并提交表单，show则会调用操作而不是更新操作。如果我不附上任何图像，那没关系。

路线

namespace :admin do
  resources :products do
    collection do
      get :download_images
      get :all_styles
      post :compress_images
    end
  end
end

看法

%h1 Edit Product

= form_for [:admin, @product], :html => {:multipart => true} do |f|
  - if f.object.accessory?
    = render 'form_accessory', :f => f
  - else
    = render 'form', :f => f

:javascript
  function exclusiveCheck(check_box) {
    if (check_box.checked) {

      check_box.checked = true;
    }
  }

  }

知道发生了什么吗？它曾经工作得很好。
