ruby on rails - Voting for nested objects using the Acts As Votable gem -


i have restaurant model has_many :dishes, through: dish_categories. found post shows how write view code necessary things going acts votable gem. situation differs being dish model nested resource that's being voted upon.

i tried translating provided code no avail. @ point should create new controller dishes , place votable actions there? if how setup route can accomplish on restaurant's show page?

models

class restaurant < activerecord::base   has_many :dish_categories, dependent: :destroy   has_many :dishes, through: :dish_categories end  class dishcategory < activerecord::base   belongs_to :restaurant    has_many :dishes, dependent: :destroy    delegate :name, to: :dish_category, prefix: "category"   delegate :restaurant, to: :dish_category end  class dish < activerecord::base   belongs_to :dish_category end

restaurants controller

... def upvote   @restaurant = restaurant.find(params[:id])   @dish = dish.find(params[:id])   @dish.liked_by current_user   redirect_to @restaurant end  def downvote   @restaurant = restaurant.find(params[:id])   @dish = dish.find(params[:id])   @dish.disliked_by current_user   redirect_to @restaurant end ...

routes

resources :restaurants   member     put "upvote", to: "restaurants#upvote"     put "downvote", to: "restaurants#downvote"   end end

restaurants - show view

... <% @restaurant.dishes.each |dish| %>     <div>         <h2><%= dish.category_name %></h2>          <b><%= dish.name %></b>          <%= link_to "upvote", like_restaurant_path(dish), method: :put %>          <%= link_to "downvote", dislike_restaurant_path(dish), method: :put %>     </div> <% end %>

a number of things needed done work. first order of business moving controller action dishes controller. added 2 more actions: unlike , undislike toggle functionailty.

note: logic authenticating non-registered users liking/disliking dishes still need written should started.

dishes controller

class dishescontroller < applicationcontroller   before_action :load_restaurant_and_dish, only: [:like, :unlike, :dislike, :undislike]    def     @dish.liked_by current_user     redirect_to @restaurant   end    def unlike     @dish.unliked_by current_user     redirect_to @restaurant   end    def dislike     @dish.disliked_by current_user     redirect_to @restaurant   end    def undislike     @dish.undisliked_by current_user     redirect_to @restaurant   end    private     def load_restaurant_and_dish       @dish       = dish.find(params[:id])       @restaurant = @dish.restaurant     end end

next configuring routes correspond restaurant , dish models:

routes

resources :restaurants   resources :dishes, only: [:like, :unlike, :dislike, :undislike]     member       put "like",      to: "dishes#like"       put "unlike",    to: "dishes#unlike"       put "dislike",   to: "dishes#dislike"       put "undislike", to: "dishes#undislike"     end   end end

i ended refactoring show view , created few partials reduce clutter there's little bit of logic involved:

restaurants - show view

... <%= render "restaurants/dish_partials/dishes" %> ...

dishes partial

<% @dishes.each |dish| %>   <div>     <h2><%= dish.category_name %></h2>      <span><b><%= dish.name %></b></span>      <%= render "restaurants/dish_partials/like_toggle", dish: dish %>   </div> <% end %>

like toggle partial

<% if current_user.liked? dish %>     <%= link_to "unlike", unlike_restaurant_dish_path(@restaurant, dish), method: :put %> <% else %>     <%= link_to "like", like_restaurant_dish_path(@restaurant, dish), method: :put %> <% end %>     <% if current_user.disliked? dish %>     <%= link_to "undislike", undislike_restaurant_dish_path(@restaurant, dish), method: :put %> <% else %>     <%= link_to "dislike", dislike_restaurant_dish_path(@restaurant, dish), method: :put %> <% end %>
