回形针 2.7 Ruby 1.8.7 企业版导轨 3.1.0 Imagemagick 6.6

当我在我的应用程序中上传图像时，它们会被 imagemagick 正确处理，并且它们存储在正确的路径中。但是，当我需要拿这个文件来显示时，却找不到。

保存图片：

当我需要文件时...

Started GET "/photos/original/missing.png" for 177.16.57.105 at Sun Sep 23 23:39:17 -0300 2012

ActionController::RoutingError (No route matches [GET] "/photos/original/missing.png"):

我的模型

class Product < ActiveRecord::Base
  attr_accessible :name, :description, :price, :photo, :product_type, :featured
  attr_accessor :photo_file_name
  has_attached_file :photo, :styles => { :thumb => "50x50>", :medium => "280x180>", :large => "585x400>", :short => "120x80>", :original => "200,200>" }

  TYPES = ["Belga", "Normal"]
end

表单视图

= form_for @product, :html => {:multipart => true} do |f|
  = f.file_field :photo

显示视图

= image_tag @product.photo.url(:original)

【解决方案1】：

处理图像的输出是否完整？在您的输出回形针中，仅将大小重新调整为短（120x80>）

您的 get 请求正在尝试加载 missing.jpg，如果无法找到请求，这是图像的默认设置。查看 /home/brigaderiagourmand/apps_rails/site/public/system/photos/24/ 看看是否有其他调整大小的照片。
