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…

You don’t seem to be setting @game in your create method.

It’d help if you told us what your error was.

def create

```
@home = Team.find_by_user_id(current_user.id)
@opponent = Team.find_by_name(params[:team][:name])

for player in @home.players
  player.update_attribute(:game_id, @game.id)
end

  if @game.save
    flash[:notice] = 'Game was successfully created.'

    redirect_to

```

edit\_school\_team\_game\_url(School.find\_by\_user\_id(current\_user.id),  
@home, @game)  
else  
render :action =\> “new”  
end

end

is my whole create method  
the error is that the game\_id is never actually changed for any of the  
players. it remains nil

i’m absolutely perplexed…  
Player Update (0.000416) UPDATE players SET “created\_at” =  
‘2008-04-07 12:35:45’, “school\_id” = 2, “team\_id” = 2, “first” = ‘w’,  
“updated\_at” = ‘2008-04-07 12:43:38’, “game\_id” = NULL, “last” = ‘o’  
WHERE “id” = 4

Why is it not setting game\_id???

The game hasn’t been saved and so it doesn’t have an id.
