Question

Hi I have collection in my controller for ex say

def devices=[ [id:PPL000000011906, firstName:Adam, lastName:Baines], [id:PPL000000010836, firstName:Adam, lastName:Baines], [id:PPL000000015137, firstName:Adan, lastName:Saenz], [id:PPL000000015136, firstName:Adan, lastName:Saenz]]

I will be getting the id from my view. How can I get firstname and lastname values from my Map based on the ID.

Thanks,
Siva

Basically, you can use find to locate the list entry with the given id. Here’s an example

def devices = [ [id:'PPL000000011906', firstName:'Adam', lastName:'Baines'],
                [id:'PPL000000010836', firstName:'Adam', lastName:'Baines'],
                [id:'PPL000000015137', firstName:'Adan', lastName:'Saenz'],
                [id:'PPL000000015136', firstName:'Adan', lastName:'Saenz'] ]

Closure<String> nameForId = { String id ->
  devices.find { it.id == id }?.with { map ->
    "$map.firstName $map.lastName"
  }
}

assert nameForId( 'PPL000000015136' ) == 'Adan Saenz'
