路由錯誤沒有路由匹配[GET]「/ microposts/304 - 刪除一個Micropost - Michael Hartl的railstutorial.org第11章

Question

我正在通過Michael Hartl的Ruby on Rails教程http://ruby.railstutorial.org。 ，特別是在試圖刪除一個微博時

我和這個用戶有同樣的問題Routing Error No route matches [GET] "/microposts/304"他能通過評論jQuery gem來解決問題，但它工作起來。 。幸運

這裏是我當前的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 

=>快速旁註：當我運行rails server命令時，出現錯誤No Javascript runtime on windows when running rails server，但一旦我註釋掉'sass-rails'，'coffee-rails'和'uglifier'寶石，它會成功運行。我正在使用Windows PC，並被告知這可能是Windows機器的特定問題。

而且，這裏是我的bundle install命令的當前成果：

我不知道如何解決這個問題。 爲了讓刪除方法起作用，我需要安裝一個特定的gem嗎？我感謝您的幫助！

這裏是rake routes輸出：

(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 
rs"} 
     user GET /users/:id(.:format)  {:action=>"show", :controller=>"use 
rs"} 
      PUT /users/:id(.:format)  {:action=>"update", :controller=>"u 
sers"} 
      DELETE /users/:id(.:format)  {:action=>"destroy", :controller=>" 
users"} 
    sessions POST /sessions(.:format)  {:action=>"create", :controller=>"s 
essions"} 
new_session GET /sessions/new(.:format) {:action=>"new", :controller=>"sess 
ions"} 
    session DELETE /sessions/:id(.:format) {:action=>"destroy", :controller=>" 
sessions"} 
microposts POST /microposts(.:format)  {:action=>"create", :controller=>"m 
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"} 

這裏是使用刪除方法的部分視圖的文件：

<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> 

同樣，源代碼可以在Github https://github.com/railstutorial/sample_app被查看，它只是似乎不能在我的機器上正常運行，這導致我相信這是user's問題。

Answer 1

我想你錯過了其中的一個。

//= require jquery 
//= require jquery_ujs 

我不小心刪除了// =需要jquery_ujs，這給了我同樣的問題。

Answer 2

您是否在應用程序中同時使用了prototype和jquery？
我可以看到你正在使用jquery-rails gem，但是原型也存在嗎？
檢查是否正在加載，因爲它們相互衝突。
