Question

im working in a project writen in ruby on rails and im currently using the active admin gem for its content manager system of my site im just wondering how active admin is using the delete action im trying to overide it but i my code doesent work, i think we are having a problem in how to get the specific line to be destroy

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   

Answer 1

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])’?
