Saving attribute
Something is getting lost here.
def create
@home = Team.find_by_user_id(current_user.id)
for player in @home.players
player.update_attribute(:game_id, @game.id)
end
end
def show
@players = Player.find_all_by_game_id(params[:id])
end
view
<%= @players.size %> # mistakenly equals zero
Played with the console and everything should be working fine...

Has_Many - Saving Child Rows
I have read extensively on has_many but cannot find an explicit example
on how to do what I need. I am a newbie, but can grasp it if I see it in
a working example. Here is my scenario...
I have a form which I can add a TODO item (patterned after
http://darkhost.mine.nu:81/~vince/rails/tutorial.html). I have the form
working perfectly so I decided to modify it a bit to add more
functionality.

DoubleRenderError exception
The DoubleRenderError exception recently introduced is forcing me to go back and rewrite my apps authentication handler. Before I could do a redirect right in the middle of a request. Whatever was happening after that went unnoticed, I assumed it was simply ending the request after the redirect was called, but apparently it was going on and rendering the page.

Generic ''save'' function for multiple objects?
I''ve been working with developing a few rails/mysql applications to
replace some rather shoddy access databases that are currently in use
here.
It''s going well but I ran into one area that I''m curious if there is a
way to improve. Basically the database has several instances of
Many-to-Many relationships to handle different things.
At present each of these has a

Save only inserts null instead of actual values
Hi,
whenever I try to save my form, rails only enters null values in my
database. I''m using sqlite, I thought that sqlite might be the problem,
but the problem remains when I switched to mysql. Here is my code:
controller:
class CollectionController < ApplicationController
def new
@collection = Collection.new

observer
on city doesn''t populate Locality. Now sure whats wrong with my code.
