# Controller def create @person = Person.new(params[:person]) @address = Address.new(params[:address]) ... end If a person has an address, how can I save some data into 2 different tables? Can I do the following? @person.address = @address if @person.save render ... else render_text "Error" end Or do I have to use: if @person.save if @address.save render ... else render_text "Error" else render_text "Error" end

I found this example that it is supposed to be working def add_player case @request.method; when :get @team = Team.find(params[:id]) @player = Player.new when :post @team = Team.find(params[:id]) @player = Player.new(params[:player]) @team.players << @player if @team.save flash[:notice] = 'Player was successfully added.' redirect_to :action => 'show', :id => params[:id] else render :action => 'add_player' end end end Unfortunately the << is for arrays. Then I have tried something like: @team.player = @player if @team.save ... else ... end Now the error is "Cannot add or update a child row: a foreign key constraint fails" What does that mean? Any ideas?
