我想使用普通文件存储适配器存储我的图像。

这是我的PAPERCLIP_STORAGE_OPTS:

PAPERCLIP_STORAGE_OPTS = {
    :styles => { :thumb => '170x170!#', :medium => '450x300!>', :large => '600x400!>',:desktop => '750x300!>'},
    :convert_options => { :all => '-quality 100' },
    :processor       => [ :papercrop ],
    :path => "/opt/www/myapp/images/:class/:attachment/:id_partition/:style/:filename"
  }

这是我的模特:

class User < ActiveRecord::Base

  attr_accessor :PAPERCLIP_STORAGE_OPTS

  has_attached_file :user_photo, PAPERCLIP_STORAGE_OPTS_THUMB

当用户上传照片时 - 它实际上会将图像存储在我的系统上的正确位置:

/opt/www/myapp/images/users/user_photos/000/000/050/original/picture

然而,当我去展示图像时,就像这样:

<%=image_tag current_user.user_photo.url(:thumb), :height=> "30", :width=> "30" %>

找不到图像,在我的日志中,我看到此网址上的图片请求:

ActionController::RoutingError (No route matches [GET] "/system/users/user_photos/000/000/050/thumb/picture"):

创建的完整网址是:

https://www.myapp.com/system/users/user_photos/000/000/050/thumb/picture?1460285803 - 无法解决。

如何配置回形针以允许我的图像存储在此特定网址/ opt / www / myapp / images /中,并且仍可通过我的rails应用程序中的Paperclip正确访问和链接?

您必须设置网址选项:

对我来说是:

  has_attached_file :avatar, :styles => { :medium => "300x300>", :thumb => "100x100>", :small=>"60x60>" },
                         :path => ':rails_root/public/system/:class/:id/:style/:filename',
                         :url => '/system/:class/:id/:style/:filename'

您不确定是否直接在app文件夹中存储图像,因此您可以尝试(从控制台测试并修改它):

:path => "/opt/www/myapp/images/:class/:attachment/:id_partition/:style/:filename",
:url => '/images/:class/:attachment/:id_partition/:style/:filename'
