Question

我正在尝试使用以下方法删除记录：method =＆gt; ：删除，但它调用GET而不是。它重定向显示并显示404未找到。但如果我回去刷新，记录会被删除。

<% @photos.each do |photo| %>
<div class='photogallery'>
<%= link_to image_tag(photo.image_url(:thumb)) if photo.image? %>
<div class="name"><%= photo.caption %></div>
<div class="actions">
<%= link_to "edit", edit_admins_photogallery_path(photo) %> |
<%= link_to "remove",admins_photogallery_path(photo), :method => 'delete',:confirm => 'Are you sure?' %> |

</div>
</div>
<% end %>

的application.js

//= require jquery
//= require jquery_ujs
//= require jquery-fileupload/basic
//= require jquery-fileupload/vendor/tmpl
//= require dataTables/jquery.dataTables
//= require bootstrap
//= require bootstrap-select
//= require jquery.timepicker
//= require jquery.ui.tabs
//= require jquery.ui.datepicker
//= require jquery.ui.accordion
//= require jquery.ui.autocomplete
//= require strftime-min.js
//= require turbolinks
//= require_tree .

我已经包含在我的布局文件中并且已经加载好了。

<%= csrf_meta_tag %>
<%= javascript_include_tag "application", "data-turbolinks-track" => true %>

奇怪的部分是它用于几天前工作，现在它已停止为所有控制器工作。

编辑：routes.rb

devise_for :users
root 'index#index'
resources :reprint
devise_scope :user do
get "/admins/", :to => "devise/sessions#new"
end
namespace :admins do
resources :location,:dashboard,:lodge,:room,:booking,:rate_calendar,:photogallery    
end  
resources :index do 
collection do
match 'search' => 'index#search', via: [:get, :post], as: :search
match 'location' => 'index#location', via: [:get, :post], as: :location
match  'add_cart' => 'index#add_cart', via: [:get, :post], as: :add_cart
end
end
resources :room_availability

编辑：photogallery_controller.rb

def destroy
  @photos = Photogallery.find(params[:id])
 if @photos.destroy
  redirect_to admins_photogallery_path, notice: "Photo was successfully destroyed."
 else
  render :action => 'index'
  flash[:error] = "Photo could not be deleted."
 end
end

Answer 1

我遇到了同样的问题，当我将link_to更改为button_to时，一切都开始正常运行。也许是因为link_to主要用于GET调用，而button_to用于POST调用（在我的情况下也是DELETE）。

Answer 2

def destroy
  @photos = Photogallery.find(params[:id])
 if @photos.destroy
  redirect_to admins_photogalleries_path, notice: "Photo was successfully destroyed."
 else
  render :action => 'index'
  flash[:error] = "Photo could not be deleted."
 end
end

我相信你设置正确，你只是在redirect_to调用中输了一个错字。 admins_photogallery_path是显示页面。 admins_photogalleries_path是索引页面。除非您在路由中明确指定，否则您无法进行GET请求并达到destroy方法。 GET和DELETE动词都说同一条路径 - 如果你确实在使用GET请求，你只需要进入显示页面就不会发生任何事情。任何被删除的东西都表明正在成功完成DELETE请求。

调用Rails GET方法而不是DELETE
