Rails中乱码解决方案

#Rails

针对 ruby on rails 开发中碰到的乱码问题, 整理了一下网上的解决方案:

1.确定MySQL数据库编码是utf8

2.config/database.yml里面增加encoding: utf8

3.确定rhtml文件编码是UTF-8

4.设置ApplicationController的header里charset

class ApplicationController < ActionController::Base 
  before_filter :configure_charsets 
  def configure_charsets 
    @response.headers["Content-Type"] = "text/html; charset=utf-8" 
    suppress(ActiveRecord::StatementInvalid) do 
      ActiveRecord::Base.connection.execute 'SET NAMES utf8' 
    end 
  end 
end

5.针对迁移migration加UTF-8编码

class CreateUsers < ActiveRecord::Migration 
  def self.up 
    create_table :users, : options => 'CHARSET=utf8' do |t| 
      t.column :name, :string 
      t.column :password, :string 
      t.column :birthday, :datetime 
      t.column :email, :string 
      t.column :address, :text 
    end 
  end 

  def self.down 
    drop_table :users 
  end 
end
