尝试获取特定游戏的评论

Question

我正在尝试查看对我创建的特定游戏的评论。现在我的 reviews/index 展示了所有游戏，而不仅仅是我正在寻找的特定游戏。我假设它只是我的参数中缺少的东西但不确定...

这些是我的控制器...

class ReviewsController < ApplicationController
  before_action :set_review, only: [:show, :edit, :update, :destroy]
  before_action :authenticate_user!, except:[:index, :show]
  before_action :correct_user, only: [:edit, :update, :destroy]

  def index
    @reviews = Review.all
  end

  def show
    @review = Review.find(params[:id])
  end 
...
class GamesController < ApplicationController
  before_action :set_game, only: [:show, :edit, :update, :destroy]
 
  def index
    @games = Game.all
  end


  def show
  end

我的路线...

reviews#index
                                      POST   /games/:game_id/reviews(.:format)                                                        reviews#create
                      new_game_review GET    /games/:game_id/reviews/new(.:format)                                                    reviews#new
                     edit_game_review GET    /games/:game_id/reviews/:id/edit(.:format)                                               reviews#edit
                          game_review GET    /games/:game_id/reviews/:id(.:format)                                                    reviews#show
                                      PATCH  /games/:game_id/reviews/:id(.:format)                                                    reviews#update
                                      PUT    /games/:game_id/reviews/:id(.:format)                                                    reviews#update
                                      DELETE /games/:game_id/reviews/:id(.:format)                                                    reviews#destroy
                                games GET    /games(.:format)                                                                         games#index
                                      POST   /games(.:format)                                                                         games#create
                             new_game GET    /games/new(.:format)                                                                     games#new
                            edit_game GET    /games/:id/edit(.:format)                                                                games#edit
                                 game GET    /games/:id(.:format)                                                                     games#show
                                      PATCH  /games/:id(.:format)                                                                     games#update
                                      PUT    /games/:id(.:format)                                                                     games#update
                                      DELETE /games/:id(.:format)                                                                     games#destroy
                                 root GET    /                                                                                        games#index

这就是我尝试做我的 link_to 的方式，但它显示了我的种子中的所有游戏评论，而不仅仅是单个游戏及其所有评论...

<%= link_to 'reviews', game_reviews_path(game_id: @game.id), @reviews %>

我自己的第一个 RoR prj，任何帮助都会很棒！！

谢谢！

Answer 1

不起作用的原因是您没有使用传递给 ReviewsController 的 game_id。您需要查询属于特定游戏的评论。

def index
  @reviews = Review.where(game_id: params[:game_id]).all
end
