Grails indexed parameters

Question

I have a list of Team objects that have an Integer seed property. I want to edit all the teams\' seeds at once, in a single form. I\'m sure

Answer 1

I finally figured out how to do this without any shenanigans.

Forget about the hidden parameter and just use the team ID in the seed parameter. In the GSP:

 
... 
   
     
   
 

Then, in the controller:

params.teams.seeds.each { teamId, seed ->
  def team = Team.get(teamId.toInteger())
  team.seed = seed.toInteger()
  team.save()
}
redirect(action:list)

Works like a charm.
