我使用Ruby中的sequel
gem连接到sqlite数据库(由rails提供)。我有各种User
和各种Project
s。我想找到唯一的项目对象user.username/project.name
,如果它存在。做这件事最优雅的方式是什么?我有连接工作等等,我有:在续集中使用基本连接
DB = Sequel.connect 'sqlite:///path/to/sqlite'
class User < Sequel::Model
end
class Project < Sequel::Model
end
# How do I retrieve the project object using project_name, user_name
# project.name == project_name
# project.user_id = xxx
# and there is a user with id xxx and username user_name?
