Question

我在Rails应用程序中使用Paperclip gem进行图像上传。但在观点中，没有图像。缺失图像的路径为http://localhost:3000/assets/。这是代码：

<div class="advert_images">
  Фото: <br>
  <% if @advertising.image.url %>
    <%= image_tag(@advertising.image) %>    
  <% end %>
  <br>
  Розташування на карті: <br>
  <% if @advertising.map.url(:normal) %>
    <%= image_tag(@advertising.map.url(:normal)) %>
  <% end %>
</div>

奇怪的是，在代码<%= @advertising.image.url %>中添加了一个显示现有图像的正确路径（例如/system/adverts/images/000/001/408/original/luxot.gif?1355951576）。

模特：

# -*- encoding : utf-8 -*-
class Advert < ActiveRecord::Base
attr_accessible :adress, :category, :city, :desc, :map_path, :name, :image_path, :map,        :image
has_attached_file :map, :styles => {:normal => "350x265", :thumb => "250x165"}
has_attached_file :image, :styles => {:normal => "350x265", :thumb => "250x165"}

  validates :name,  :length => {:in => 2..20}, :presence => true
  validates :category,                         :presence => true
  validates :city,                             :presence => true
  validates :adress,                           :presence => true


scope :by_city, lambda {|city| where("city = ?", city)}
scope :by_category, lambda {|category| where("category = ?", category)}

end

Answer 1

找到解决方案。我更改了默认路径，其中回形针存储图像。

  has_attached_file :image,
                :url => "/assets/:id/:style/:basename.:extension",
                :path =>  
                ":rails_root/app/assets/images/:id/:style/:basename.:extension"

来自image_tag的错误网址和Rails中的回形针
