在使用Ruby脚本活动记录和mysql

问题描述

我一直在试图使用mysql和活动记录的Ruby脚本，但我得到了以下信息：过时的mysql的宝石。升级到2.8.1或更高版本。在您的Gemfile：创业板MySQL的，2.8.1。或者使用宝石'mysql2（RuntimeError）。之前，我得到一个消息，关于创业板mysql2失踪，但后来我检查了在活动记录的连接适配器源$ C ​​$ C，只见它需要哪些我没有安装mysql的宝石。

这是我的脚本：

 需要'rubygems的'
需要'active_record
需要'机械化'
需要'引入nokogiri
需要'active_record
需要'mysql2
创业板mysql2

的ActiveRecord :: Base.establish_connection（{
  ：适配器=＆GT; MySQL的，
  ：主机=＆GT; 本地主机，
  ：用户名=＆GT; 根，
  ：密码=＆GT; ，
  ：数据库=＆GT; rainalytics}）

的ActiveRecord :: Schema.define（：版本=＆GT; 20110320035328）办

    CREATE_TABLEscore_logs：力=＆GT;真做| T |
      t.integerblog_posts
      t.integer特色
    结束

    CREATE_TABLE用户，：力=＆GT;真做| T |
      t.datetimecreated_at
      t.datetime的updated_at
    结束

  结束


    类用户的LT;的ActiveRecord :: Base的
      的has_many：score_logs
    结束
    类ScoreLog＆LT;的ActiveRecord :: Base的
      belongs_to的：用户
  结束
 

解决方案

我不是用'需要'mysql2'或'宝石'mysql2'部分，它似乎是工作的罚款，我也有另外的{}内的ActiveRecord :: Base的块

希望这可以帮助别人的未来：）的

这是我使用
红宝石1.9.2p318（2012-02-14改版34678）的x86_64-darwin11.2.0]
Rails的3.1.0

---

 规定的RubyGems
要求active_record

的ActiveRecord :: Base.establish_connection（{
  ：适配器=＆GT; mysql2
  ：主机=＆GT; 本地主机，
  ：用户名=＆GT; 根，
  ：密码=＆GT; 根，
  ：数据库=＆GT; cybercellar}）

类区＆LT;的ActiveRecord :: Base的

结束

区= Zone.all
打印区域
 

然后，我浏览到我的应用程序文件夹，运行
文件

I've been trying to use mysql and active record on a ruby script but I'm getting the following message: Outdated mysql gem. Upgrade to 2.8.1 or later. In your Gemfile: gem 'mysql', '2.8.1'. Or use gem 'mysql2' (RuntimeError). Before I was getting a message about gem 'mysql2' missing but then i checked the source code on the connection adapters in active record and saw that it require mysql gem which i didnt have installed.

this is my script:

require 'rubygems'
require 'active_record'
require 'mechanize'
require 'nokogiri'
require 'active_record'
require 'mysql2'
gem 'mysql2'

ActiveRecord::Base.establish_connection ({
  :adapter => "mysql",
  :host => "localhost",
  :username => "root",
  :password => "",
  :database => "rainalytics"})

ActiveRecord::Schema.define(:version => 20110320035328) do

    create_table "score_logs", :force => true do |t|
      t.integer  "blog_posts"
      t.integer  "featured"
    end

    create_table "users", :force => true do |t|
      t.datetime "created_at"
      t.datetime "updated_at"
    end

  end


    class User < ActiveRecord::Base
      has_many :score_logs
    end
    class ScoreLog < ActiveRecord::Base
      belongs_to :user
  end

解决方案

Im not using the 'require 'mysql2' or 'gem 'mysql2' parts, and it seems to be working fine, I also have additional {} inside the ActiveRecord::Base block

hope this can help someone in future :)

This is what I use
ruby 1.9.2p318 (2012-02-14 revision 34678) [x86_64-darwin11.2.0]
Rails 3.1.0

---

require "rubygems"
require "active_record"

ActiveRecord::Base.establish_connection ({
  :adapter => "mysql2",
  :host => "localhost",
  :username => "root",
  :password => "root",
  :database => "cybercellar"})

class Zone < ActiveRecord::Base

end

zone = Zone.all
print zone

then I navigate to my app folder and run the file
