無法在rails中搜索鏈接

Question

我試圖通過從Rails進行簡單搜索來搜索標題/正文。但是當我試圖把匹配的字符串放在標題/正文中時，它不能顯示期望的結果。你能幫我檢查一下嗎？謝謝你在前進

article.rb

def self.search(query) 
    # where(:title, query) -> This would return an exact match of the query 
    where("title LIKE ? or body LIKE ?", "%#{query}%", "%#{query}%") 
    end 

控制器

if params[:search] 
     @articles = Article.search(params[:search]) 
    #@articles = Article.where(["title || body like ?","%#{params[:search]}%"]) 
    else 
     @articles = Article.all 
    end 

顯示

<%= form_tag(articles_path, :method => "get", id: "search-form") do %> 
<%= text_field_tag :search, params[:search], placeholder: "Title or body" %> 
<button class="btn btn-success-outline" type="submit">Search</button>

OK，簡單瀏覽了一下在GitHub上的代碼的其餘部分，問題是here：

def index 
    #@articles = Article.all 
    if params[:search] 
    @articles = Article.search(params[:search]) 
    #@articles = Article.where(["title || body like ?","%#{params[:search]}%"]) 
    else 
    @articles = Article.all 
    end 
    @markdown = Redcarpet::Markdown.new(Redcarpet::Render::HTML) 
    if params[:tag] 
    @articles = Article.tagged_with(params[:tag]) 
    else 
    @articles = Article.all 
    end 
end 

檢查params[:search]你之後檢查params[:tag]從您的搜索表單提交時，它將爲空白。這意味着@articles只是被文章的完整列表（@articles = Article.all）所取代。
