请多多包涵，因为我是 Rails 和一般编程新手。我对模型、视图、控制器的功能了解非常有限，但我一直在尽可能快地学习。

我无法根据已有的数据生成半静态中间页面。现在它只是一个邮政编码搜索，一个带有结果列表的页面和一个商店页面。我希望它由 State-city-list-shop 构成

在我的数据库中，商店位置已经过地理编码，并且可以通过邮政编码搜索在客户端访问。因此，我正在处理具有通常脚手架类型设置的 Shops 控制器，因此显示视图的 url 看起来像 /shops/1。我想要的是带有面包屑的商店/阿拉斯加/安克雷奇/商店名称。

我没有“州”或“城市”控制器，我认为您必须这样做才能构建路线。

我制作了静态的 State 模板页面，对于每个 State，我都列出了带有类似City链接的城市。我在每个 State 文件夹中都有一个 index.html 文件，但 /shop/state/city 中没有任何内容

我这样做是因为我可以从中得到结果：

/shops/find_shops?=zip=City&Distance=5
如果我能得到/state/city/shops的相同结果，我会很高兴。

因为那时我可以单击该列表中的一家商店，它会将我带到/shops/7499 (:id) 的商店页面，最好有/state/city/shop-name

这是商店控制器- 管理员只是保护公众免于编辑商店地址信息。正如您将看到的，它正在获取一个 csv 文件，解析并保存到数据库中。

    def admin_index
    #@shops = Shop.find(:all)

    @shops = Shop.paginate( :per_page => 35, 
                   :page => params[:page])

    @shops_to_geocode = Shop.fetch_not_geocoded
  end

  def geocode_shops
    @shops_to_geocode = Shop.fetch_not_geocoded
    cnt = 0
    for shop in @shops_to_geocode
      shop.geocode_raw_address
      shop.save!
    end
    redirect_to :action => 'admin_index'
  end

  def upload_file
    file_path = params[:file_path]
    if file_path
      Shop.import( file_path )
    end
    redirect_to :action => 'admin_index' 
  end

  # GET /shops
  # GET /shops.xml
  def index
    @zip = params[:zip]
    @distance = params[:distance]

    if @zip && @distance 
      @shops = Shop.find(:all, :origin => @zip, :conditions => ["distance < ?", @distance])
      logger.debug( "found #{@shops.length} shops" )

      if @shops.length == 0
        geo = GeoKit::Geocoders::MultiGeocoder.geocode( @zip )
        errors.add(:address, "Could not Geocode address") if !geo.success
        @centerLat, @centerLng = geo.lat,geo.lng if geo.success
      else
        @centerLat = @shops[0].lat
        @centerLng = @shops[0].lng
      end
    else
      @shops = []

      geo = GeoKit::Geocoders::IpGeocoder.geocode(request.remote_ip)
      if geo.success
        @centerLat, @centerLng = geo.lat,geo.lng 
      else
        logger.debug( "unable to geocode remote ip" )
        @centerLat = 42 
        @centerLng = -120 
      end
    end

    if @distance.nil?
      @distance = 5
    end

这里是Shop.rb

require 'net/http'

class Shop < ActiveRecord::Base

  acts_as_mappable

  DATA_FILE_COLS =
    [
      "---",
      "Site",
      "Zip Search",
      "Shop",
      "Address",
      "Phone",
      "Make",
      "Affiliations",
      "Specialties",
      "Amenities",
      "Timestap",
    ]

  FIELDS = 
    {
      "---" => "-1",
      "Site" => "-1",
      "Zip Search" => "-1",
      "Shop" => "name",
      "Address" => "raw_address",
      "Phone" => "phone_number",
      "Make" => "make",
      "Affiliations" => "affiliations",
      "Specialties" => "specialties",
      "Amenities" => "amenities",
      "Timestap" => "-1"
    }


  def full_address
    "#{address_1} #{city} #{state} #{postal_code}"
  end

  def valid_for_geocoding?
    rtn = true 
    if self.full_address.nil? || self.full_address.to_s.empty? 
       rtn = false 
    end

    return rtn 
  end

  def geocode_address
    geo = GeoKit::Geocoders::MultiGeocoder.geocode( full_address )
    errors.add(:address, "Could not Geocode address") if !geo.success
    self.lat, self.lng = geo.lat,geo.lng if geo.success
  end

  def geocode_raw_address
        geo = GeoKit::Geocoders::MultiGeocoder.geocode(self.raw_address)
        if ( geo.success )
          self.address_1 = geo.street_address
          self.city = geo.city
          self.state = geo.state
          self.postal_code = geo.zip
          self.lat = geo.lat
          self.lng = geo.lng
        end
  end

  def self.import( file_path )
    url = 'http://example.com'
    #file = '/filename.txt'
    file = file_path


    response = Net::HTTP.get_response(URI.parse(url + file))
    body = response.body
    lines = body.split("\r\n")

    line_cnt = 0

    lines.each { |line| 
      if line_cnt > 1
        words = line.split("\"")
        cnt = 0
        shop_atrbs = Hash.new
        words.each { |word|
          if word != ","
            #puts "#{fields[cnt]} : #{word.strip}"
            field = FIELDS[DATA_FILE_COLS[cnt]]
            if field != "-1"
              shop_atrbs[field] = word.strip
            end
            cnt = cnt + 1
          end
        }
        shop = Shop.new
        shop.update_attributes(shop_atrbs)
        geo = GeoKit::Geocoders::MultiGeocoder.geocode(shop.raw_address)
        shop.address_1 = geo.street_address
        shop.city = geo.city
        shop.state = geo.state
        shop.postal_code = geo.zip
        shop.lat = geo.lat
        shop.lng = geo.lng
        shop.save

      end
      line_cnt = line_cnt + 1
    }    #f.each{ |line| puts '#{f.lineno}: #{line}' }
  end

  def self.fetch_not_geocoded
    find( :all,
    :conditions => ['lat IS NULL || lng IS NULL || lat = ? || lng = ?', "", ""],
    :limit => 10000)
  end

  def self.find_for_sitemap(offset, limit)
    find( :all, 
          :select => 'id, name, updated_at',
          :order => 'updated_at DESC',
          :offset => offset,
          :limit => limit )
  end

end

所以，我想要的工作是 - /Alaska/Anchorage/Shops-List/（干净的 URL）

我现在能做的是 - /find_shops?zip=anchorage&distance=5

最后，这是 rails 2.3.2，我花了很多时间试图将其转换为 rails 3.0，但还没有成功。

您是否阅读过 Rails 路由指南“从外到内的 Rails 路由”？特别是第 4 节介绍了如何实现这一点。
