レビューを編集する際に以下のエラーが表示されることがありますが、レビューは更新されますが、以下のエラーが出てきます。 Ps：私はレールの初心者です。 ReviewsController＃更新中

NoMethodErrorは

私のコントローラは、以下の通りである。この

class ReviewsController < ApplicationController 
 
    before_action :authenticate_user! 
 
    before_action :set_listing 
 
    before_action :set_review, only: [:edit, :update, :destroy, :upvote, :downvote] 
 
    before_action :check_user, only: [:edit, :update, :destroy] 
 

 
    # GET /reviews

    def index 
 
    @reviews = Review.all 
 
    end 
 

 
    # GET /reviews/1

    def show 
 
    end 
 

 
    # GET /reviews/new 
 
    def new 
 
    @review = Review.new 
 
    end 
 

 
    # GET /reviews/1/edit 
 
    def edit 
 
    end 
 

 
    #Added the def upvote and downvote 
 
    def upvote 
 
    @listing = Listing.find(params[:listing_id])

    @review = Review.find(params[:id]) 
 
    @review.downvote_from current_user 
 
    redirect_to :back 
 
    end

    private 
 
    # Use callbacks to share common setup or constraints between actions. 
 
    def set_review 
 
     @review = Review.find(params[:id]) 
 
    end 
 

 
    #Check user 
 

 
    def check_user 
 
     unless (@review.user == current_user) || (current_user.admin?) 
 
     redirect_to root_url, alert: "Sorry, this review belongs to someone else, you can only edit reviews you have posted." 
 
     end 
 
    end 
 

 
    #set listing 
 

 
    def set_listing 
 
     @listing = Listing.find(params[:listing_id]) 
 
    end 
 

 
    # Never trust parameters from the scary internet, only allow the white list through. 
 
    def review_params 
 
     params.require(:review).permit(:rating, :comment, :upvote, :downvote) 
 
    end 
 
    
 
end

マイroutesファイルのように見えます

Answer 1

あなたはReviewsControllerであなたのupdate actionに@reviewにリダイレクトされていますが、それを取る、あなたのroutes.rbでそれを免除し、すべてが問題ないはずです。 except配列から:showを削除するだけです。
