I’m a newbie in rails and working on my first project with it. I have a
database that uses a self reference through a join model to add
favorite players. In the join model I have an additional attribute for
players to make notes of each favorite player.
My problem is I’m having difficulty editing the note attribute. All the
favorite players are displayed all at once along with their notes. I do
this by using fields_for, but I can only capture the first note of the
page when I post.
##view
< fields_for “favorite_user”, @favs[index] do |favorite_note| %>
<= favorite_note.text_area :note, “rows” => 5 %>
< end %>
##controler
def favorites
if request.get?
@players = Player.find(params[:id]).favorites
@favs = FavoriteUser.find_all_by_player_id(params[:id])
elsif request.post?
self_player = Player.find(params[:id])
p @params ##check to see if I got all the notes?
end
end
model
class Player < ActiveRecord::Base
has_many :favorite_users
has_many :favorites, :through => :favorite_users
end
class FavoriteUser < ActiveRecord::Base
belongs_to :player
belongs_to :favorite, :foreign_key => “favorite_id”, :class_name =>
“Player”
end
database tables
CREATE TABLE players (
id int(11) NOT NULL auto_increment,
username varchar(50) NOT NULL,
PRIMARY KEY (id)
);
CREATE TABLE favorite_users (
player_id int(11) default NULL,
favorite_id int(11) default NULL,
note varchar(100) default NULL
);
