active-admin rails

1、创建项目

 rails new demo3 --skip-bundle

2、配置

bundle install 

3、生成

rails g active_admin:install

rails g active_admin:install User

rails g devise:views

rails g model product name:string num:integer

rails g model provider name:string num:integer

rails g active_admin:resource product

rails g active_admin:resource provider

rake db:migrate

4、启动服务

vi /config/initializers/active_admin.rb

config.comments = false
config.show_comments_in_menu = false

5、生产环境

部署生产环境：nginx+passenger

1、gem install passenger

2、passenger-install-nginx-module

3、修改配置文件

location / {
            index  index.html index.htm;
            root /home/yuecl/rails/ttttt/public;
            passenger_enabled on;
            rails_env production;
        }

4、rake secret RAILS_ENV=production //生成production 的key

rake db:migrate RAILS_ENV=production 

rake db:seed RAILS_ENV=production 

rake assets:precompile RAILS_ENV=production

修改config/secrets.yml 替换为获取到的key

nginx start
