链接到不同的搜索结果视图

我有一个页面显示3个搜索结果列表:插图,小说和标签。我想允许用户单击每个列表的链接以查看缩略图网格。我不能为我的生活弄清楚如何将搜索结果对象传递给新的页面。我只是得到插图ID的字符串。

main_controller的搜索方法,以及我要对show_illustrations做的事情:

def search
    @search_criteria = params[:search]
    @novels = Novel.search(params[:search])
    @illustrations = Illustration.search(params[:search])
    @tags = Tag.search(params[:search])

    respond_to do |format|
      format.html #search_results.html.erb
    end
  end

 def show_illustrations
    @illustrations = params[:illustrations]
 end

显示搜索结果中插图列表的部分。应用程序坚持调用main的show方法,即使我将link_to语句中的操作分配给'show_illustrations':

<% if @illustrations.size() > 0 %>
        <div class="row-fluid">
        <div class="span8">
        <h3>Illustrations</h3>
        </div>
        <div class="span4">
        <%= link_to "View", {:controller => "main", :action => "show_illustrations", :illustrations => @illustrations}, :class => "btn btn-mini"%>
        </div></div>    
            <div class="search_results well-search-results">
                <table class="table table-striped table-condensed">
                    <% @illustrations.each do |illustration| %>
                        <tr>
                            <td><%= illustration.name %></td>
                            <td><%= link_to "Show", illustration, :class => "btn btn-primary btn-mini", :style => "float:right;" %></td>
                        </tr> 
                    <% end %>
                </table>
            </div>
        <% else %>
            <h3>No Matching Illustrations</h3>
        <% end %>

应显示插图网格的页面,标题为searching_illustrations.html.erb:

<div class="container">
    <div class="well padding:0px;">
    <% @illustrations.each_slice(4) do |set| %>
      <div class="row-fluid">
        <% set.each do |illustration| %>
          <div class="span3">
            <div style="text-align:center"><%= link_to image_tag(illustration.image_thumbnail_url), illustration %>
              <br />
              <%= illustration.name %><br />
              <%= link_to illustration.novel.name, illustration.novel %> - 
              <%= illustration.novel.edition %>
              <% if ! illustration.tags.empty? %>
                <br />
                <% illustration.tags.each do |tag| %>
                  <%= tag %>
                <% end %>
              <% end %>
            </div>
           <br />
          </div>
      <% end %>
      </div>
      <br \>
    <% end %>
  </div>
</div>

routes.rb中:

match 'main/show_illustrations' => 'main#show_illustrations', as: :show_illustrations

如果您更具体地了解您正在使用哪种搜索gem,那么它会有很大帮助,但让我们假设您使用meta_searchmeta_search,我相信其他一些搜索宝石,会返回类Search的对象,您需要调用.results方法来获取搜索结果。

就像你如何打电话@users = User一样,你必须致电@users = User.all。在这种情况下,它是@listings = Listing.search(params[:search]).results.all

这很糟糕,但这是一个解决方案:

在搜索控制器中:

def show_illustrations
    @arr = params[:illustrations]
    @illustrations = Array.new

    @arr.each do |id|
        illustration = Illustration.find(id)
        @illustrations << illustration
    end

    @illustrations = Kaminari.paginate_array(@illustrations).page(params[:page]).per(20)
 end
