在我的应用程序中,我已经有上传图片的回形针,但需要更改以接受图像和视频.图像已经在具有belongs_to关系的模型中定义,称为Attachment.由于视频也将是相同父模型的附件(在我的案例中,文章),我想Attachment为图像和视频重用相同的模型.这是一个好主意吗？

我的代码 attachment.rb是:

class Attachment < ActiveRecord::Base

  belongs_to :article 

  has_attached_file :url, :s3_protocol => :https , 
    styles: { 
      medium: "300x300>", thumb: "100x100>", big: "1200x1200>", normal: "600x600>" 
    }

  validates_attachment_content_type :url, content_type: /\Aimage|\Avideo\/.*\Z/

  validates_attachment :url, content_type: { content_type: ["image/jpeg", "image/gif", "image/png", "video/mp4"] }

end

但事实并非如此,它并没有在S3上存储视频.我在终端上得到以下内容

Command :: file -b --mime '/var/folders/v_/pf2bsxnj1y37ccd2pjksv7z80000gn/T/f3e2afc957bb9fb2aa3e77e69359c48920160131-13311-pyeez1.mp4'

如果这已经得到回答并且我找不到它,请道歉.任何方向将不胜感激.

使用Rails 4.1.4,Paperclip 4.2.0和Simple Form 3.0.2.

之后Submit,我has an extension that does not match its contents在表单错误消息中得到输出.

检查是否存在回形针附件：我正在尝试查看附件是否选择了一个文件/图像，然后会出现类似这个新视图的情况。所以在我点击浏览后，选择一个我想要发生的事情！！谢谢！

当我执行此代码时没有任何反应！

家庭视图：

<% if @post.image.present? %>
            <%= render 'posts' %>
            <% end %>

所以我有这个Dockerfile尝试以下列方式安装ImageMagick:

FROM ruby:2.4-alpine

...

RUN apk --update add imagemagick

...

关键是容器无法识别file实用程序(用于内容类型检测).

本地环境(Mac OSX上,安装imagemagick有brew):

> file --version
file-5.25
magic file from /usr/share/file/magic

> convert --version

在Google Cloud上部署应用程序时出现问题

所含内容与所报告的内容不符

在本地工作正常！我已经尝试使用command_path。所以我真的不知道下一步该怎么做...

这是我的模特

  validates_attachment_content_type :image, :content_type => ["image/jpg", "image/jpeg", "image/png", "image/gif"]

感谢你付出的努力。我希望你们能帮助我
