我已经在轨道中实现了回形针,正如各种教程所推荐的那样.在尝试上传照片时,我始终如一地获得以下内容:

这是我的模型声明:

attr_accessor :image_file_name
  has_attached_file :image, 
    :styles …

Rails 3 app with paperclip.

给定Paperclip文件模型,如何将该回形针文件移动到不同的回形针,比如图库？哪个会有不同的处理规则等？

有任何想法吗？

我正在寻找使用rails_admin进行多文件上传的快速解决方案.

有什么想法或解决方案吗？

我在S3上使用paperclip生成过期的签名URI.但是,在每个请求中,我生成一个不理想的新URI,它会强制浏览器在每次刷新页面时从S3下载一组新图像.

我想要做的是将生成的URI缓存的时间少于它们在S3上过期的时间.有没有人之前做过这样的事情,可以建议一个解决方案.

如果这表明解决方案(或不是),我正在heroku上部署

我正在使用CKEditor并且我已将其配置为与Paperclip一起使用但我不能告诉它在S3中存储文件,因此它使用Paperclip存储它们但在本地文件系统上.

所以我想知道是否有某种方法告诉Paperclip每次使用时都明确使用S3.

我知道如何在某些模型上配置带有S3的Paperclip(非常简单,在paperclip github wiki上有描述).我正在Heroku上部署,这就是我无法写入本地文件系统的原因.

出于某种原因,每当我将所有图像从所有用户中删除时,Capistrano都会删除我数据库中的所有图像.通常,我所做的是必须使用capistrano删除的相同图像重新填充数据库.我已经附上了我的deploy.rb文件,有人可以给我一些见解.

require "bundler/capistrano"
set :rvm_ruby_string, '1.9.3p429'
set :rvm_type, :user
set :user, ""
set :password, ""
set :domain, ""
set :applicationdir, ""

set :scm, :git
set :repository,  ""
set :git_enable_submodules, 1 # if you have vendored rails
set :branch, "release"
set :rails_env, 'production'

#set :git_shallow_clone, 1
set :scm_verbose, true

# roles (servers)
role :web, domain
role :app, domain
role :db,  domain, :primary => true
set :port, 22


# deploy config
set :deploy_to, applicationdir
set :deploy_via, :remote_cache

# additional settings
default_run_options[:pty] = …

我正在使用带有 Rails4 的 Paperclip。我有以下图片

现在我想调整大小和裁剪图像，但它被裁剪并且图像的方向被移位，如下所示

:photo,
    :path => ":rails_root/public/system/:attachment/:id/:style/:filename",
    :url => "/system/:attachment/:id/:style/:filename",
    :styles => {
        :small => { :geometry => "100x100!" },
        :medium => { :geometry => "500x500!"}
}

我使用rails 4 nested_form为我的模型创建一个表单.模型相册有很多图像.上传图片的部分表格如下:

<div class="field">
    <%= f.fields_for :images do |image_form| %>
        <div>
          <%= image_form.file_field(:image_file) %>
          <%= image_form.link_to_remove "Remove this image" %>
        </div>
    <% end %>
</div>

如何在编辑表单上为每个图像显示一个拇指？目前只有编辑时出现浏览按钮.

无论如何在Ruby on Rails中转换图像URL(https://meo-fb-natal-dev.s3.amazonaws.com/participations/cropped/56658c5de2fc7116340000c0/635769180217506883-GD5A9264.jpg?1449495643)中托管的图像Base64编码？

我已经尝试了很多东西,但它们似乎都没有用.

我想创建一个小票系统:http ://ticketsystemkm.herokuapp.com/
我有电影海报在主站点上显示它们.
当我制作新电影时,一切都很好,但几个小时后图像消失了.也许有人有类似的问题,知道如何解决它.
