ruby-on-rails

Ruby on rails 如何获取离开日期为零或应该在rails中特定日期范围内的记录？,ruby-on-rails,date-range,Ruby On Rails,Date Range,我想在employee模型上编写一个query，其中employee离开日期为nil，或者应该在特定的日期范围内 以下是我当前的查询： e = Employee.where.not('date_of_leaving >= ? and date_of_leaving <= ?', Date.today - 60, Date.today).where(:date_of_leaving => nil) e=Employee.where.not（'date\u of_leaving>

我想在
employee
模型上编写一个
query
，其中
employee
离开日期
为
nil
，或者应该在特定的
日期范围内

以下是我当前的查询：


e = Employee.where.not('date_of_leaving >= ? and date_of_leaving <= ?', Date.today - 60, Date.today).where(:date_of_leaving => nil)



e=Employee.where.not（'date\u of_leaving>=？date\u of_leaving以下查询将返回所有在指定日期之间或
nil
有
date\u of_leaving
的员工：


Employee.where('date_of_leaving BETWEEN ? AND ? OR date_of_leaving IS NULL', Date.today - 60, Date.today)
