Question

我正试图通过Rails中的简单搜索来搜索标题/正文。但是当我试图将匹配的字符串放在title / body中时，它无法显示期望的结果。你能帮我检查一下吗？提前谢谢你
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

显示

<%= 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>

好的，快速浏览一下GitHub上的其余代码，问题是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

在检查params[:search]后，您需要检查params[:tag]，当您从搜索表单提交时，该@articles将为空白。这意味着@articles = Article.all只会被完整的文章列表（ExpectedException）替换。
