Record Association Type Mismatch

I have nested results after matches like this

/ matches / 16 / results / 13 / change

If I have the following select box, this shows the correct information (team.name and her team.id)

<%= f.collection_select :winner, @select_winner_loser, :id, :name %>

      

        
        
        
      

    

Now when I try to change my result and pick a winner, I get this:

ActiveRecord :: TeamTypeMismatch Team (# 10504340) expected, received string (# 6163240)

"Hoisted when the object assigned to the association is of the wrong type." http://api.rubyonrails.org/classes/ActiveRecord/AssociationTypeMismatch.html

The winner is the team , result.rb looks like this

class Result < ActiveRecord::Base
    has_one :match
    belongs_to  :winner, class_name: "Team"
    belongs_to  :loser, class_name: "Team"
end

      

        
        
        
      

    

@select_winner_loser comes from my results_controller method

  def edit
    @select_winner_loser = []
    @select_winner_loser << @match.top
    @select_winner_loser << @match.bottom
  end

      

        
        
        
      

    

Match.top and bottom are also commands

class Match < ActiveRecord::Base
    belongs_to  :top, class_name: "Team"
    belongs_to  :bottom, class_name: "Team"
    ...
    belongs_to  :result
end

      

        
        
        
      

    

I don't understand why I would get this because I have the correct objects in my select box, any ideas?

thank
