ruby on rails - No route matches {:action=>"up_vote", :controller=>"votes", :post_id=>"1"} -

i've been receiving following error in rspec when trying upvote method pass:

failures: 1) votescontroller#up_vote adds up-vote post  failure/error: post( :up_vote, post_id: @post.id )  actioncontroller::urlgenerationerror:    no route matches {:action=>"up_vote", :controller=>"votes", :post_id=>"1"} 

now can upvote , downvote when i'm on server, it's test won't work.

here's code:

votes_controller_spec.rb

require 'rails_helper'  describe votescontroller    include testfactories   include devise::testhelpers    describe '#up_vote'     "adds up-vote post"       request.env["http_referer"] = '/'       @user = authenticated_user       @post = associated_post       sign_in @user        expect {         post(:up_vote, post_id: @post.id)       }.to change { @post.up_votes }.by 1     end   end end 

votes_controller.rb

class votescontroller < applicationcontroller   before_action :load_post_and_vote    def up_vote     update_vote!(1)     redirect_to :back   end    def down_vote     update_vote!(-1)     redirect_to :back   end    def update_vote!(new_value)      if @vote       authorize @vote, :update?       @vote.update_attribute(:value, new_value)     else       @vote = current_user.votes.build(value: new_value, post: @post)       authorize @vote, :create?       @vote.save     end   end    private    def load_post_and_vote     @post = post.find(params[:post_id])      @vote = @post.votes.where(user_id: current_user.id).first   end end 

routes.rb

rails.application.routes.draw    devise_for :users   resources :users, only: [:update]   resources :questions   resources :advertisements    resources :topics     resources :posts, except: [:index]       resources :summaries, only: [:create, :new, :show]       resources :comments, only: [:create, :destroy]        post '/up-vote', to: 'votes#up_vote', as: :up_vote       post '/down-vote', to: 'votes#down_vote', as: :down_vote     end   end    'about' => 'welcome#about'   'contact' => 'welcome#contact'    root to: 'welcome#index'  end 

module providing methods within specs:

module testfactories   def associated_post(options={})     post_options = {         title: 'post title',         body: 'post bodies must pretty long.',         topic: topic.create(name: 'topic name'),         user: authenticated_user     }.merge(options)      post.create(post_options)   end    def authenticated_user(options={})     user_options = {email: "email#{rand}@fake.com", password: 'password'}.merge(options)     user = user.new(user_options)     user.skip_confirmation!     user.save     user   end end 

relevant rake routes

topic_post_up_vote post   /topics/:topic_id/posts/:post_id/up-vote(.:format)       votes#up_vote topic_post_down_vote post   /topics/:topic_id/posts/:post_id/down-vote(.:format)     votes#down_vote 

any ideas why i'm getting url generation error?

i think need pass topic_id post method this: post( :up_vote, post_id: @post.id, topic_id: @post.topic.id )
