Initializing list with account creation

rubyonrails-talk
1

I have a model for users and a model for lists and a model for the items.

I have a one-to-one relationship with the user and the list so only one list may be created.

I'm having problems when I try to create the list at the same time I create the user so they are related by the foreign key on the list. How would I go about doing this.

right now I'm trying

def new   @user = User.new   @user.list.build end

But I get an error message saying that list is nil. I know the problem must be with passing the user_id to the list model, but I have no idea how to do this.

Try @user.build_list.

If a user could have many lists, you'd use @user.lists.build.

Thanks Jeremy. I ended up using your solution in the create method after initializing the object in the new method.

def new @user = User.new @list = List.new end

def create   @user = User.new(params[:user])   @user.build_list end
