rendering form, and display the input on the same page - ruby-on-rails

Question

so I'm trying to create a videogame review website for practice. each game would have it's own page, and on each page, i'd like to have a form where you can input reviews, and have it show up on the same page when submitted.
I'm not sure how to handle this. but I managed to create two controllers -- one for creating games, and one for creating reviews.
I use devise for user logins/registration
I'll post the codes below: please let me know if you need to see other files.
routes.rb
Rails.application.routes.draw do
devise_for :users
resources :games
resources :reviews
root "games#index"
end
games_controller.rb -- to create new games
class GamesController < ApplicationController
before_action :set_game, only: [:show, :edit, :update, :destroy]
def index
#games = Game.all
end
def new
#game = Game.new
end
def create
#game = Game.create(game_params)
redirect_to #game
end
def edit
end
def update
#game.update(game_params)
redirect_to #game
end
def destroy
end
private
def game_params
params.require(:game).permit(:title, :image, :developer, :genre, :release_date, :platform)
end
def set_game
#game = Game.find(params[:id])
end
end
reviews_controller.rb -- to create reviews
class ReviewsController < ApplicationController
before_action :set_review, only: [:show, :edit, :update, :destroy]
def index
end
def show
end
def new
#review = Review.new
end
def create
#review = Review.create(review_params)
redirect_to #review
end
private
def review_params
params.require(:review).permit(:review)
end
def set_review
#review = Review.find(params[:id])
end
end
show.html.erb for games
<% if user_signed_in? %>
<p class=""><%= link_to "Update Details", edit_game_path %></p>
<p class=""><%= link_to "Update News", new_game_path %></p>
<% end %>
<%= flash[:notice] = "Successfully updated." %>
<hr>
<div class="game_summary">
<%= image_tag #game.image %>
<div class="game_details">
<h3 class="game_title"><%= #game.title %></h3>
<ul class="game_info">
<li>Developer: <%= #game.developer %></li>
<li>Release Date: <%= #game.release_date %></li>
<li>Genre: <%= #game.genre %></li>
<li>Platform(s): <%= #game.platform %></li>
</ul>
<button class="buttons" id="buy">Buy</button>
<button class="buttons" id="rent">Rent</button>
</div>
</div>
<div class="game_news">
<h2 class="game_news_title">News & Articles</h2>
</div>
<div class="game_reviews">
<%= link_to "Add Review", new_review_path %>
<h2>Reviews</h2>
<ul>
<li><%= %></li>
<li><%= %></li>
<li><%= %></li>
<li><%= %></li>
</ul>
</div>

Answer 1

In your games_controller.rb, you'd need a show method (which is created by default when you use scaffolding, but which you somehow missed). This show method would gather all the reviews pertaining to the game in question, assuming your Review model has a reference to its corresponding Game model (both as a foreign key specified in schema.rb and via belongs_to and has_many in their respective models).
The show method would look like this:
def show
#reviews = Review.where("game_id = ?", #game.id)
end
Then in your view, you'd have something like this:
<% #reviews.each do | review | %>
<%= review.title %>
<%= review.content %>
<% end %>
I have no idea what fields are contained in your Review object, but you can extrapolate from this example to get what you want.
