Just trying a simple example to try to get nested to work... but can't
get it! Been 2 days! Please help. VERY SIMPLE controller, view,
models... listed below.

----------------------ERROR
MESSAGE----------------------------------------------------------------------

ActiveRecord::AssociationTypeMismatch in UserController#update_player

Racquet(#38866740) expected, got Array(#20762670)

-------------------------------------------------------------------------------------------------------------------------

-----------------MODELS-------------------------------------

class Player < ActiveRecord::Base

has_many :racquets, :dependent => :destroy

accepts_nested_attributes_for :racquets

end


class Racquet < ActiveRecord::Base

belongs_to :player

end

--------------CONTROLLER-----------------------------

class UserController < ApplicationController

def index
@player = Player.new
@player.racquets.build
end


def update_player
@player = Player.new(params[:player])
@player.save
redirect_to :action => :index
end

end

----------------------- VIEW
-------------------------------------------

<div>
<% form_for :player, :url => { :action => :update_player, :id =>
@player.id } do |f| %>

Name: <%= f.text_field :name %> <br>
Rank: <%= f.text_field :rank %> <br>

<% f.fields_for :racquets do |racquets_form| %>

Racquet Name: <%= racquets_form.text_field :typ %> <br>
<% end %>

<%= f.submit "Submit" %>
<% end %>
</div>

--------------------------------------------------------------------------------

This was supposed to be quick practice form to make use of nested
models.... and has turned into a nightmare. Can anyone tell my why it
is not working???

Thanks so much,

Shawn
