Question

我正在http://ruby.railstutorial.org处理Michael Hartl的Ruby on Rails教程。我在第11章遇到了麻烦，特别是在尝试删除微博时。

我遇到与此用户Routing Error No route matches [GET] "/microposts/304"相同的问题。他能够通过注释掉jQuery gem来解决这个问题。然而，我没那么幸运。

这是我目前的Gemfile：

source 'http://rubygems.org'

gem 'rails', '3.1.1'

# Bundle edge Rails instead:
# gem 'rails',     :git => 'git://github.com/rails/rails.git'

gem 'sqlite3'
gem 'gravatar_image_tag', '1.0.0.pre2'
gem 'will_paginate', '3.0.pre2'

gem 'jquery-rails'
gem 'pg'

group :development do
  gem 'faker', '0.3.1'
end


# Gems used only for assets and not required
# in production environments by default.
#group :assets do
#  gem 'sass-rails',   '~> 3.1.4'
#  gem 'coffee-rails', '~> 3.1.1'
#  gem 'uglifier', '>= 1.0.3'
#end

# To use ActiveModel has_secure_password
# gem 'bcrypt-ruby', '~> 3.0.0'

# Use unicorn as the web server
# gem 'unicorn'

# Deploy with Capistrano
# gem 'capistrano'

# To use debugger
# gem 'ruby-debug19', :require => 'ruby-debug'

group :test do
  # Pretty printed test output
  gem 'turn', :require => false
end

=＆GT;快速注意事项：运行rails server命令时出现错误No Javascript runtime on windows when running rails server，但一旦我注释掉'sass-rails'，'coffee-rails'和'uglifier'宝石它会成功运行。我正在使用Windows PC，并被告知这可能是Windows机器的特定问题。

此外，这是我的bundle install命令的当前结果：

我不确定如何解决这个问题。 我是否需要安装特定的gem才能使删除方法正常工作？我感谢您的帮助！

以下是rake routes输出：

(in C:/rails_projects/sample_app)
      users GET    /users(.:format)          {:action=>"index", :controller=>"us
ers"}
            POST   /users(.:format)          {:action=>"create", :controller=>"u
sers"}
   new_user GET    /users/new(.:format)      {:action=>"new", :controller=>"user
s"}
  edit_user GET    /users/:id/edit(.:format) {:action=>"edit", :controller=>"use

       user GET    /users/:id(.:format)      {:action=>"show", :controller=>"use

            DELETE /users/:id(.:format)      {:action=>"destroy", :controller=>"

    session DELETE /sessions/:id(.:format)   {:action=>"destroy", :controller=>"

icroposts"}
  micropost DELETE /microposts/:id(.:format) {:action=>"destroy", :controller=>"
microposts"}
     signup        /signup(.:format)         {:controller=>"users", :action=>"ne
w"}
     signin        /signin(.:format)         {:controller=>"sessions", :action=>
"new"}
    signout        /signout(.:format)        {:controller=>"sessions", :action=>
"destroy"}
    contact        /contact(.:format)        {:controller=>"pages", :action=>"co
ntact"}
      about        /about(.:format)          {:controller=>"pages", :action=>"ab
out"}
       help        /help(.:format)           {:controller=>"pages", :action=>"he
lp"}
       root        /                         {:controller=>"pages", :action=>"ho
me"}

以下是使用delete方法的部分视图文件：

<tr>
  <td class="micropost">
    <span class="content"><%= micropost.content %></span>
    <span class="timestamp">
      Posted <%= time_ago_in_words(micropost.created_at) %> ago.
    </span>
  </td>
  <% user = micropost.user rescue User.find(micropost.user_id) %>
  <% if current_user?(user) %>
  <td>
    <%= link_to "delete", micropost, :method => :delete,
                                     :confirm => "You sure?",
                                     :title => micropost.content %>
  </td>
  <% end %>
</tr>

同样，源代码可以在Github https://github.com/railstutorial/sample_app上查看，它似乎在我的机器上运行不正常，这让我相信这是user's这个问题。

Answer 1

我认为你错过了这两个中的一个。

//= require jquery
//= require jquery_ujs

我不小心删除了// = require jquery_ujs，这给了我同样的问题。

Answer 2

您是否在自己的应用中使用了原型和jquery？我可以看到你正在使用jquery-rails gem，但原型也存在吗？
检查两者是否都被加载，因为它们相互冲突。
