Rails - Votes not saving, and creating button that does not submit? - ruby-on-rails

Question

so I'm trying to create a video game review website for practice.
A game has many reviews, and votes. The idea is, in order to post a review, you must vote "Good" or "Bad" first, THEN submit a review. You can't post a text review without voting.
I'm trying to do this without the acts_as_voteable gem...
The data format for votes is boolean. "Good" is true, "Bad" is false.
How do I get the votes to save? below are my routes.rb, _review partial, reviews controller, and show page.
many thanks guys :)
edit****: also I'm trying to only one vote per user. I was thinking of using a token variable which equals to 1, and when a vote is cast, the token is -1. Is that a good approach? But the data type for vote is boolean, so how would that work -- or should I change the data type for vote from boolean to integer?
edit#2 -- so I added :vote into my params.
routes.rb
upvote_game_review_path
POST /games/:game_id/reviews/:id/upvote(.:format) reviews#upvote
downvote_game_review_path
POST /games/:game_id/reviews/:id/downvote(.:format) reviews#downvote
Rails.application.routes.draw do
devise_for :users
root "games#index"
resources :games do
resources :news
resources :reviews, except: [:show, :index] do
member do
post "upvote"
post "downvote"
end
end
end
resources :platforms
resources :genres
end
reviews_controller.rb
class ReviewsController < ApplicationController
before_action :set_review, only: [:show, :update, :edit, :destroy]
before_action :set_game
before_action :authenticate_user!
def new
#review = Review.new
end
def create
#review = Review.new(review_params)
#review.user_id = current_user.id
#review.game_id = #game.id
if #review.save
redirect_to #game
else
render "review"
end
end
def upvote
#review.vote.create = true
redirect_to #game
end
def downvote
#review.vote.create
#review.vote = false
redirect_to #game
end
def edit
#review.update(review.params)
end
def destroy
#review.destroy
redirect_to #game
end
private
def set_review
#review = Review.find(params[:id])
end
def set_game
#game = Game.find(params[:game_id])
end
def review_params
params.require(:review).permit(:comment, :vote)
end
end
_review partial <-- to create a new review
<%= form_for [#game, #reviews.new] do |r| %>
<h3 class="post_review">Review this game</h3>
<p>
<%= r.text_area :comment %>
</p>
<p>
<%= button_to "Good", upvote_game_review_path(#game.id, r) %>
</p>
<p>
<%= button_to "Bad", downvote_game_review_path(#game.id, r) %>
</p>
<p>
<%= r.hidden_field :game_id, value: #game.id %>
<p>
<%= r.submit %>
<% end %>
show.html.erb
<p><%= link_to "<< Home", games_path %></p>
<span><%= link_to "Edit", edit_game_path(#game) %></span>
<span><%= link_to "Delete", game_path(#game), method: :delete %></span>
<div class="game_summary">
<h2><%= #game.title %></h2>
<%= image_tag #game.image %>
<p>Release Date: <%= #game.release_date %> </p>
<p>Genre: <%= #game.genre_id %> </p>
<p>Platforms: <%= #game.platform_id %></p>
</div>
<%= link_to "Add News", new_game_news_path(#game) %>
<h2>News & Articles</h2>
<%= link_to "view all", game_news_index_path(#game) %>
<% #news.each do |n| %>
<ol>
<li><%= link_to n.title, game_news_path(#game.id, n.id) %></li>
</ol>
<% end %>
<div class="game_review submit">
<%= render "review" %>
</div>
<% #reviews.each do |review| %>
<p><%= review.comment %></p>
<p><%= link_to "delete", game_review_path(#game.id, review.id), method: :delete %></p>
<% end %>

Answer 1

You don't specify which review you're loading in. The reason is here:
before_action :set_review, only: [:show, :update, :edit, :destroy]
You don't pull in the request's review instance when you go to either of those actions. Further, it doesn't look like you're actually saving them.
So, two things I'd recommend:
Add those methods to your before_action:
before_action :set_review, only: [:show, :update, :edit,
:destroy, :upvote, :downvote]
(May not be necessary, write tests to confirm this!) Actually save the entity after you've changed its value.
def upvote
#review.vote.create = true
#review.save
redirect_to #game
end
def downvote
#review.vote.create unless #review.vote
#review.vote = false
#review.save
redirect_to #game
end
