Question

I’m trying to make a sql with grails, and I couldn’t make it so far…

I have 3 domain classes:

class Device {
  String imei   
  List nodes
  static hasMany = [nodes:Node]
}

class Node {
  Integer signal
  static belongsTo = [network : Network]
}

class Network {
  String ssid
  static hasMany = [nodes: Node]
}

So, it’s kind of a many to many relation with 3 tables (I need this third table, because I need to have some vars in it)

I need to find all the Networks of one device(by imei). Any ideas..?

Thanks!

Answer 1

Doesn’t:

def networks = Device.findByImei( 'whatever' ).nodes*.network?.unique( false )

do it?
