我对 Ruby on Rails 相当陌生，将目录类型的网站作为个人项目来学习。

在我的应用程序中，我实现了地理编码器搜索，因此用户可以搜索他们附近的地点/位置，搜索效果很好。但是当我添加选项卡式菜单来分类可用的地方类型时，它破坏了搜索。

我想我知道它为什么坏了，但不知道如何修复它。选项卡显示@schools、@restaurants 和@businesses 变量，我怎样才能让选项卡显示搜索结果而不是那些变量？这些变量应该只在没有执行搜索时显示，但它们也会在搜索执行时显示。

这是我的代码：

地方控制器：

    class PlacesController < ApplicationController
    before_filter :authenticate_user!, except: [:index]

    def index
    if params[:search].present?
     @places = Place.near(params[:search], 50, :order => :distance)
    else
     @places = Place.all
    end

    @schools = Place.where("category = ?", "School")
    @restaurants = Place.where("category = ?", "Restaurant")
    @businesses = Place.where("category = ?", "Business")

    end

地方索引.html.erb：

        <% if user_signed_in? %>

 <div class="row">
    <h2>Newly Added Places</h2>

        <%= form_tag places_path, :method => :get do %>
                <%= text_field_tag :search, params[:search], placeholder: "Enter your zipcode or city", class: "search-query"  %>
                <%= submit_tag "Search Nearby", :name => nil, class: "btn"%>
        <% end %>

            <ul class="nav nav-tabs">
                    <li><a href="#tab1" data-toggle="tab">Schools</a></li>
                    <li><a href="#tab2" data-toggle="tab">Restaurants</a></li>      
                    <li><a href="#tab3" data-toggle="tab">Businesses</a></li>
                </ul>

            <div class="tab-content">
                <div class="tab-pane active" id="tab1">
                    <%= render :partial => "places", :locals => {:places_container => @schools} %>
                </div>
                <div class="tab-pane" id="tab2">
                    <%= render :partial => "places", :locals => {:places_container => @restaurants} %>
                </div>
                <div class="tab-pane" id="tab3">
                    <%= render :partial => "places", :locals => {:places_container => @businesses} %>
                </div>
            </div>
</div>

<br />

<% else %>

<%= render 'static_pages/home' %>

<% end %>

地方部分（_places.html.erb）：

     <table class="table table-hover table-condensed">
<thead>
        <tr>            
         <th>Image</th>
       <th>Name</th>
       <th>Address</th>
         <th>State</th>
         <th>City</th>
         <th>Type</th>
       <th>Website</th>
     </tr>
</thead>
<% places_container.each do |place| %>
    <tr>
        <th><%= image_tag place.image(:medium)%></th>
        <th><%= link_to place.name, place %></th>
      <td><%= place.address %></td>
      <td><%= place.state %></td>
      <td><%= place.city %></td>
        <td><%= place.category %></td>
      <td><%= place.website %></td>

        <% if current_user.admin? %>
          <td><%= link_to 'Edit', edit_place_path(place) %></td>
          <td><%= link_to 'Destroy', place, method: :delete, data: { confirm: 'Are you sure?' } %></td>
        <% end %>
        </tr>
<% end %>
</table>

您的选项卡式结果忽略了搜索参数，因为您没有使用@places从搜索参数构建的关系。要修复，请更改此代码：

def index
  if params[:search].present?
   @places = Place.near(params[:search], 50, :order => :distance)
  else
   @places = Place.all
  end

  @schools = Place.where("category = ?", "School")
  @restaurants = Place.where("category = ?", "Restaurant")
  @businesses = Place.where("category = ?", "Business")
end

到：

def index
  if params[:search].present?
   @places = Place.near(params[:search], 50, :order => :distance)
  else
   @places = Place.scoped  # use 'scoped', not 'all', to avoid triggering the query immediately
  end

  @schools = @places.where("category = ?", "School")
  @restaurants = @places.where("category = ?", "Restaurant")
  @businesses = @places.where("category = ?", "Business")
end
