第一个网站
使用SQLite3测试:
#### If you want to use SQLite (not recommended)
rails new myapp
#### If you want to use MySQL
rails new myapp -d mysql
#### If you want to use Postgres
# Note that this will expect a postgres user with the same username
# as your app, you may need to edit config/database.yml to match the
# user you created earlier
rails new myapp -d postgresql
# Move into the application directory
cd myapp
# If you setup MySQL or Postgres with a username/password, modify the
# config/database.yml file to contain the username/password that you specified
# Create the database
rake db:create
rails server
打开 http://localhost:3000 即看到封面。
第一个CRUD功能
rails generate scaffold Person first_name:string last_name:string phone_number:string address:text
rake db:migrate
rake db:migrate RAILS_ENV=production
现在打开 http://localhost:3000/people 即有一个人员管理CRUD页面。
Jruby下运行Rails
安装Java
先卸载openjdk:
yum -y remove java*
安装oracle jdk
sudo rpm -i jdk-8u112-linux-x64.rpm
安装Jruby
56 rbenv install --list
57 rbenv global jruby-9.1.5.0
58 jruby –v
修改Gemfile
去掉自动生成的:
gem 'activerecord-jdbcsqlite3-adapter'
在末尾增加:
platform :jruby do
gem 'activerecord-jdbc-adapter', git: 'https://github.com/jruby/activerecord-jdbc-adapter.git', branch: 'rails-5'
gem 'activerecord-jdbcsqlite3-adapter', git: "https://github.com/jruby/activerecord-jdbc-adapter.git", branch: 'rails-5'
gem 'listen'
end
运行
bundle install
jruby –S rails server
