Delete方法不能在Rails的调用

问题描述：

所以我采取在我看来，删除用户的方法，这是我users_controllerDelete方法不能在Rails的调用

def destroy 
@user = User.find(params[:id]) 
@user.destroy 
respond_to do |format| 
    format.html { redirect_to users_path, notice: 'This user was successfully destroyed.' } 
    format.json { head :no_content } 
end 
end

而且我认为，破坏方法：

<td><%= link_to 'Delete', users_path(user), method: :delete, data: { confirm: 'Are you sure?' } %></td>

和的application.js

// This is a manifest file that'll be compiled into application.js, which will include all the files 
// listed below. 
// 
// Any JavaScript/Coffee file within this directory, lib/assets/javascripts, vendor/assets/javascripts, 
// or vendor/assets/javascripts of plugins, if any, can be referenced here using a relative path. 
// 
// It's not advisable to add code directly here, but if you do, it'll appear at the bottom of the 
// compiled file. 
// 
// Read Sprockets README (https://github.com/sstephenson/sprockets#sprockets-directives) for details 
// about supported directives. 
// 
//= require jquery 
//= require jquery_ujs 
//= require bootstrap-sprockets 
//= require_tree .

，并在布局/ application.html.erb我：

<%= javascript_include_tag 'default' %>

每次我点击了破坏链接，它只是刷新并不会删除。我应该提到的是该视图是superadmins下的，而superadmins_controller是从users_controller继承而来的，我在这里写了destroy方法。我认为route.rb可能有问题，但我不能提出解决方案。我的route.rb看起来像这样：

Rails.application.routes.draw do 
root to: 'visitors#index' 
devise_for :users, :path =>'u' 
devise_scope :user do 
    get '/u/sign_out' => 'devise/sessions#destroy' 
    end 
    resources :users 
    resources :superadmins 
end

谢谢！

你有没有重新启动服务器？ – MZaragoza

刚刚做到了。仍然可以在控制台上使用 – DevArenaCN

，您可以检查是否在页面加载时收到了任何js错误，并确保jQuery现在已加载 – MZaragoza

答

尝试改变： <%= javascript_include_tag 'default' %> 到：<%= javascript_include_tag 'application' %> 因为控制台中的第一个错误是ActionController::RoutingError (No route matches [GET] "/javascripts/default.js")

这样做。谢谢！ – DevArenaCN

你是walcome – Younes

答

UPDATE有看看你的路由定义和你的link_to助手（它被指定method: :delete。尝试改变

get '/u/sign_out' => 'devise/sessions#destroy'

到

delete '/u/sign_out' => 'devise/sessions#destroy'

我的问题不是注销，那很好。我的问题是，当我管理用户时，我无法删除它们。 – DevArenaCN

答

我相信你的问题是您使用的users_path而不是正确user_path

所以改变这种

<td><%= link_to 'Delete', users_path(user), method: :delete, data: { confirm: 'Are you sure?' } %></td>

这个

<td><%= link_to 'Delete', user_path(user), method: :delete, data: { confirm: 'Are you sure?' } %></td>
