我不明白爲什麼會發生這種情況，似乎即使找到了friendly.id文章的id也被查詢。即使在與評論關聯時找到正確的article_id（59），我發現的任何文章的ID都爲「0」。Ruby on Rails文章加載回滾在show.html.erb

Processing by ArticlesController#show as HTML 
    Parameters: {"id"=>"javascript-8"} 
    User Load (0.6ms) SELECT "users".* FROM "users" WHERE "users"."id" = $1 ORDER BY "users"."id" ASC LIMIT $2 [["id", 1], ["LIMIT", 1]] 
    Article Load (0.7ms) SELECT "articles".* FROM "articles" WHERE "articles"."slug" = $1 LIMIT $2 [["slug", "javascript-8"], ["LIMIT", 1]] 
    (1.9ms) BEGIN 
    Article Load (0.3ms) SELECT "articles".* FROM "articles" WHERE "articles"."id" = $1 LIMIT $2 [["id", 0], ["LIMIT", 1]] 
    (1.1ms) ROLLBACK

    Comment Load (0.7ms) SELECT "comments".* FROM "comments" WHERE "comments"."article_id" = 59 ORDER BY created_at DESC 
    Rendered comments/_comment.html.erb (25.2ms)

編輯：文章控制器

class ArticlesController < ApplicationController 
    before_action :authenticate_user! 
    before_action :set_article, only: [:show, :edit, :update, :destroy, :toggle_vote] 
    impressionist :actions=>[:show] 

    def show 
    @article_categories = @article.categories 
    @comments = Comment.where(article_id: @article).order("created_at DESC") 

    if @article.status == "draft" && @article.user != current_user 
     redirect_to root_path 
    end 
    end 

    private 

    def set_article 
     @article = Article.friendly.find(params[:id]) 
    end 

end

發佈您的過濾器或操作之前 - 其中「@ article」本身是否正在加載？ –

可否請您將代碼呈現給文章鏈接。謝謝 – Hirurg103

@CodyCaughlan使用之前的過濾器編輯 – doyz

friendly_id：FOO，使用：猛擊＃你必須做 MyClass.friendly.find（ '巴'）

或...

friendly_id：foo，使用方法：[：猛擊，：發現者]＃你現在可以做 MyClass.find（ '巴'）

在你的情況

def set_article 
    @article = Article.friendly.find(params[:id]) 
end

這是因爲我用印象派的寶石。

我應該在控制器的頂部除去

impressionist :actions=>[:show]

，而是在表演中添加此F你使用friendly_id

def show 
    impressionist(@article) 
end

寫在印象派寶石使用指南（https://github.com/charlotte-ruby/impressionist#usage），」請確保以這種方式記錄印象派，因爲params [：id]將返回一個字符串（url slug），而impressionable_id是數據庫中的整數列。「
