Rails - 播种HABTM协会

Question

Equipment.create(name: "Room to run")
Equipment.create(name: "Pull-up bar")
Workout.create(
  description: "Do 100 pull-ups then run 5km",
  :equipment => Equipment.where(:name => 'Pull-up bar'))

设备和锻炼有HABTM关系.上面的种子代码有效,但我怎么能同时分配第二个设备协会？

Answer 1

在where条件中,您可以使用数组:

Equipment.create(name: "Room to run")
Equipment.create(name: "Pull-up bar")
Workout.create(
  description: "Do 100 pull-ups then run 5km",
  :equipment => Equipment.where(:name => ['Pull-up bar', 'Room to run']))
