Ruby on Rails - Render JSON for multiple models -

i trying render results more 1 model in json. following code in controller renders first result set:

  def calculate_quote     @moulding = moulding.find(params[:id])     @material_costs = materialcost.all      respond_to |format|       format.json  { render :json => @moulding }       format.json  { render :json => @material_costs }     end   end 

any appreciated, thanks.

one way create hash objects want render, , pass render method. so:

respond_to |format|   format.json  { render :json => {:moulding => @moulding,                                    :material_costs => @material_costs }} end 

if models aren't associated through active record, that's best solution.

if association exist, can pass :include argument render call, so:

respond_to |format|   format.json  { render :json => @moulding.to_json(:include => [:material_costs])} end 

note wouldn't have retrieve @material_costs variable in section above if take approach, rails automatically load @moulding variable.
