回形针工作在发展但不在生产中工作？

问题描述

我对轨道很陌生，似乎对回形针宝石有问题。我安装了gem，它在开发（localhost：3000）中运行良好，但是当我在heroku服务器上运行它时，出于某种原因它不想附加文件，并且应用程序中断（错误500页）。

以下是我跑过的过程...我将文件推送到heroku，heroku运行rake db：migrate（添加回形针迁移），然后运行heroku restart （通过新的迁移重新启动应用程序）。这似乎没有帮助。

这是我用于回形针的代码：

user.rb模型：

  has_attached_file：avatar，
：styles => {：small => 70x70>}，
：url => /users/:attachment/:id/:style/:basename.:extension，
：path => ：rails_root / public / users /：attachment /：id /：style /：basename。：extension
 validates_attachment_size：avatar，：less_than => 500.kilobytes 
 validates_attachment_content_type：avatar，：content_type => ['image / jpeg'，'image / png'] 
  

edit_form.html.haml view：

  = form_for（@user || User.new），：html => {：multipart => true} do | f | 
 ... 
 .profile_picture.text_field 
 = image_tag current_profile.avatar.url（：small）
％br 
 = f.file_field：avatar 
  

同样，由于某种原因，它在开发中运行良好，但在生产中出现故障。任何指针将不胜感激......我似乎不能解决这个问题，这是非常令人沮丧的。非常感谢您的时间和任何帮助！

解决方案

在您的模型中。

  has_attached_file：picture，
：styles => {：大=> 275x450>}，
：storage => ：s3，
：s3_credentials => ＃{RAILS_ROOT} /config/s3.yml，
：path => appname /：attachment /：style /：id。：extension
  

配置目录：

 开发：
 bucket：bucketname 
 access_key_id：key 
 secret_access_key：key 
 
制作：
存储桶：存储桶名称
 access_key_id：存储钥匙
 secret_access_key：钥匙
  

然后注册Amazon S3中的存储桶：

I'm pretty new to rails and seem to be having an issue with the paperclip gem. I installed the gem and it works well in development (localhost:3000) but when I'm running it on the heroku server, for some reason it does not want to attach files, and the app breaks (error 500 page).

Here is the process i ran... I pushed my file to heroku, heroku ran rake db:migrate (to add paperclip migrations), and then I ran heroku restart (to restart the app with new migrations). This did not seem to help.

Here is the code that I have for paperclip:

user.rb model:

  has_attached_file :avatar,
                    :styles => {:small => "70x70>"},
                    :url  => "/users/:attachment/:id/:style/:basename.:extension",
                    :path => ":rails_root/public/users/:attachment/:id/:style/:basename.:extension"
  validates_attachment_size :avatar, :less_than => 500.kilobytes
  validates_attachment_content_type :avatar, :content_type => ['image/jpeg', 'image/png']

edit_form.html.haml view:

  = form_for (@user || User.new), :html => { :multipart => true } do |f|
  ...
  .profile_picture.text_field
    = image_tag current_profile.avatar.url(:small)
    %br
    = f.file_field :avatar

Again, for some reason it runs great in development, but breaks down in production. Any pointers would be greatly appreciated... I just cant seem to figure this out and it's pretty frustrating. Thank you so much for your time and any help!

解决方案

In your model.

has_attached_file :picture,
                   :styles => {:large => "275x450>"},
                   :storage => :s3,
                   :s3_credentials => "#{RAILS_ROOT}/config/s3.yml",
                   :path => "appname/:attachment/:style/:id.:extension"

In s3.yml in your config dir:

    development:
      bucket: bucketname
      access_key_id: key
      secret_access_key: key

    production:
      bucket: bucketname
      access_key_id: key
      secret_access_key: key

Then go signup for a bucket at Amazon S3: http://aws.amazon.com/s3/
