我的太阳黑子搜索功能（sunspot_rails gem）在我的索引视图中工作得很好，但是当我将它复制到我的显示视图时，我的搜索中断了......

意见/供应商产品/show.html.erb

<%= form_tag supplierproducts_path, :method => :get, :id => "supplierproducts_search" do %>
  <p>
    <%= text_field_tag :search, params[:search], placeholder: "Search by SKU, product name & EAN number..." %>
  </p>
  <div id="supplierproducts"><%= render 'supplierproducts' %></div>
<% end %>

资产/javascripts/application.js

$(function () {
  $('#supplierproducts th a').live('click',
    function () {
      $.getScript(this.href);
      return false;
    }
  );

  $('#supplierproducts_search input').keyup(function () {
    $.get($("#supplierproducts_search").attr("action"), $("#supplierproducts_search").serialize(), null, 'script');
    return false;
  });
});

意见/供应商产品/show.js.erb

$('#supplierproducts').html('<%= escape_javascript(render("supplierproducts")) %>');

意见/supplierproducts/_supplierproducts.hmtl.erb

<%= hidden_field_tag :direction, params[:direction] %>
<%= hidden_field_tag :sort, params[:sort] %>
<table class="table table-bordered">
  <thead>
    <tr>
      <th><%= sortable "sku", "SKU" %></th>
      <th><%= sortable "name", "Product name" %></th>
      <th><%= sortable "stock", "Stock" %></th>
      <th><%= sortable "price", "Price" %></th>
      <th><%= sortable "ean", "EAN number" %></th>
    </tr>
  </thead>
    <% for supplierproduct in @supplier.supplierproducts %>
  <tbody>
    <tr>
      <td><%= supplierproduct.sku %></td>
      <td><%= supplierproduct.name %></td>
      <td><%= supplierproduct.stock %></td>
      <td><%= supplierproduct.price %></td>
      <td><%= supplierproduct.ean %></td>
    </tr>
  </tbody>
  <% end %>
</table>

控制器/supplierproducts_controller.rb

class SupplierproductsController < ApplicationController

helper_method :sort_column, :sort_direction

  def show
    @supplier = Supplier.find(params[:id])
    @search = @supplier.supplierproducts.search do
      fulltext params[:search]
    end
    @supplierproducts = @search.results
  end
end

private

  def sort_column
    Supplierproduct.column_names.include?(params[:sort]) ? params[:sort] : "name"
  end

  def sort_direction
    %w[asc desc].include?(params[:direction]) ?  params[:direction] : "asc"
  end

模型/供应商产品.rb

class Supplierproduct < ActiveRecord::Base
  attr_accessible :ean, :name, :price, :sku, :stock, :supplier_id
  belongs_to :supplier

  validates :supplier_id, presence: true

  searchable do
    text :ean, :name, :sku
  end
end

访问 show.html.erb 工作得很好。日志显示：

从您粘贴的日志中，搜索表单看起来正在点击index，而不是show，并且该操作未设置@supplier。
