Question

所以我在我的视图中实现了删除用户方法，这是我的users_controller中的destroy方法

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

我的观点：

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

和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 .

在layouts / application.html.erb中我有：

<%= javascript_include_tag 'default' %>

每次我点击销毁链接时，它都会刷新并且不会删除。我应该提到的是视图在superadmins下，superadmins_controller继承自users_controller，我写了destroy方法。我认为route.rb可能有问题，但我无法想出解决方案。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！

Answer 1

尝试改变： <%= javascript_include_tag 'default' %> 致：<%= javascript_include_tag 'application' %> 因为在您的控制台中，第一个错误是ActionController::RoutingError (No route matches [GET] "/javascripts/default.js")

Answer 2

查看您的路线定义和您的link_to帮助程序（指定method: :delete。尝试更改

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

到

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

Answer 3

我认为您的问题是您使用users_path而不是正确的user_path

所以改变这个

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

到这个

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

无法在Rails中调用Delete方法
