Let's Build: With Ruby on Rails - Job Board with Payments

这个案例是一个非常好的商业闭环的网站的设计。

Github Repo:

https://github.com/shenzhoudance/job_board_pay

在案例的学习过程中,可以完成五个环节的学习;

  • (1)功能体系:主要是完成一个招聘广告的发布,其中包含图片的上传;
  • (2)用户体系:使用 gem 'devise' 具备普通用户和管理员用户,没有管理员的后台?需要加上管理员的后台吗?
  • (3)设计体系:使用 gem 'bulma-rails'完成页面的设计工作,满足页面设计的需要;
  • (4)支付体系:使用 gem 'stripe' 完成支付,在这个体系使用的时候,思考 RMVC 的架构,处在 job controller 里面完成 create 广告功能。
  • (5)部署体系:使用 herkou 和 aliyun 完成部署,这一部分,没有完成,但是我可以完成教学;
