Rails和Paperclip在特定路径中存储图像会设置错误的URL

[英]Rails and Paperclip storing images in a specific path sets wrong URL

我想使用普通的文件存储适配器存储图像。

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"
  }

这是我的模型:

class User < ActiveRecord::Base

  attr_accessor :PAPERCLIP_STORAGE_OPTS

  has_attached_file :user_photo, PAPERCLIP_STORAGE_OPTS_THUMB

用户上传照片时-实际上确实将图像存储在系统上的正确位置:

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

但是,当我去显示图像时,像这样:

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

找不到图片,在我的日志中,我在以下URL上看到图片请求:

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

创建的完整URL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,以允许将图像存储在此特定的url / opt / www / myapp / images /中,并且仍然可以通过Rails应用程序中的回形针对其进行访问和正确链接?

您将必须设置URL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'

由于您直接将图像存储在app文件夹中不确定情况,因此可以尝试(从控制台对其进行测试并进行修改):

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