How do I link to parent association in rails 5? -


i trying person did rails 5.

in app have 2 controllers , 3 models.

my 2 controllers orderscontroller , listingscontroller. , 3 models order, listing, , user.

i trying create user-associated links on sales , purchases pages within orderscontroller link #show action within listingscontroller.

the links have on sales , purchases page this:

<% @orders.each |order| %>   <tr>     <td class="center"><%= link_to 'view game sold', listing_path(@listing) %></td>   </tr> <% end %>

this order model:

belongs_to :listing belongs_to :buyer, class_name: "user" belongs_to :seller, class_name: "user"

this orderscontroller:

class orderscontroller < applicationcontroller   before_action :set_order, only: [:show, :edit, :update, :destroy]   before_action :authenticate_user!    def sales     @orders = order.all.where(seller: current_user).order("created_at desc")   end    def purchases     @orders = order.all.where(buyer: current_user).order("created_at desc")   end    # /orders/new   def new     @order = order.new     @listing = listing.find(params[:listing_id])   end end

this listing model:

belongs_to :user has_many :orders has_many :fullgames  def self.search(params)   listings = # not existing params args   listings = listings.where("name ?", "%#{params[:name]}%") if params[:name]   listings end

this listingscontroller:

class listingscontroller < applicationcontroller   before_action :set_listing, only: [:show, :edit, :update, :destroy]   before_filter :authenticate_user!, only: [:seller, :new, :create, :edit, :update, :destroy]   before_filter :check_user, only: [:edit, :update, :destroy]    def seller     @listings = listing.where(user: current_user).order("created_at desc")   end    # /listings   # /listings.json   def index     @listings = listing.all.order("created_at desc").search(params).paginate(:page => params[:page], :per_page => 2)   end    # /listings/1   # /listings/1.json   def show   end end

this user model:

has_many :listings, dependent: :destroy has_many :sales, class_name: "order", foreign_key: "seller_id" has_many :purchases, class_name: "order", foreign_key: "buyer_id" 

# order model  class order < applicationrecord    scope :recent, -> { order("created_at desc") }  end  # listingscontroller class listingscontroller < applicationcontroller   ...   before_filter :authenticate_user!, only: [:show, :seller, :new, :create, :edit, :update, :destroy]    # /listings/1   # /listings/1.json   def show     @purchases = current_user.purchases.recent     @sales = current_user.sales.recent   end end  # show.html.erb # purchases orders <% @purchases.each |purchase_order| %>   <tr>     <td class="center"><%= purchase_order %></td>   </tr> <% end %>  # sales orders <% @sales.each |sale_order| %>   <tr>     <td class="center"><%= sale_order %></td>   </tr> <% end %>

recursion - Can every recursive algorithm be improved with dynamic programming? -

i first year undergraduate csc student looking competitive programming. recursion involves defining , solving sub problems. understand, top down dynamic programming (dp) involves memoizing solutions sub problems reduce time complexity of algorithm. can top down dp used improve efficiency of every recursive algorithm overlapping sub problems? dp fail work , how can identify this? the short answer is: yes. however, there constraints. obvious 1 recursive calls must overlap. i.e. during execution of algorithm, recursive function must called multiple times same parameters. lets truncate recursion tree memoization. can use memoization reduce number of calls. however, reduction of calls comes price. need store results somewhere. next obvious constraint need have enough memory. comes not-so obvious constraint. memory access requires time. first need find result stored , maybe copy location. in cases, might faster let recursion calculate result instead of loading somewher...
