def destroy


  @menu = Menu.find(params[:menu_recipe][:menu_id])
  @menu_recipe = @menu.menu_recipes.find(params[:id])
  @menu_recipe.remove_recipe
  @menu_recipe.destroy
  redirect_to @reservation, :notice => "recipe destroyed"

      end

it comes with a error of

undefined method `[]' for nil:NilClass

Probably params[:menu_recipe] is not set. Try putting params[:menu_recipe] ||= {} at the beginning.

But why is it that you're finding through the Menu, anyway? Can't you just do 'MenuRecipe.find(params[:id])'?

still the same or i didnt code it right can you please code where to put params[:menu_recipe] ||= {} im new in ruby on rails sorry - Led 2012-04-05 15:25

First, see the edit I just made. If you do need to go through Menu, the line I put should go at the very beginning of the action. Note that you'll also have to be careful before doing Menu.find(params[:menu_recipe][:menu_id]) since if the params[:menu_recipe][:menu_id] is nil, the find will raise an exception - tsherif 2012-04-05 15:33

uhm yea i re-write my code with that and it worked thanks for the help : - Led 2012-04-05 15:59
