回形针，S3，Heroku：缺少图像 [英] Paperclip, S3, Heroku: Missing Image

问题描述

长时间的观众，第一次提问。我搜索了这个主题，但不相信我找到了答案。

我有一个Post模型，它有一个图像。我使用Paperclip gem，保存到Amazon S3，并在Heroku上托管。

文件上传表单工作正常，因为我可以看到图像发送给我S3桶。

问题在于，图片实际上并未显示在制作中。

这是我的模型：

  class Post< ActiveRecord :: Base 
 attr_accessor：image_file_name，：image_content_type，：image_file_size，：image_updated_at 
 belongs_to：用户
 has_many：评论
 
 has_attached_file：图片，样式：{中等：700x500＃，小：350x250> } 
 validates_attachment_content_type：image，content_type：/\Aimage\/.*\/ 
  

 ＃Paperclip / AWS需要
 config.paperclip_defaults = {
：storage => ：s3，
：s3_credentials => {
：bucket => ENV ['S3_BUCKET_NAME']，
：access_key_id => ENV ['AWS_ACCESS_KEY_ID']，
：secret_access_key => ENV ['AWS_SECRET_ACCESS_KEY'] 
} 
} 
  

这里是我的节目。 html.haml文件：

  .clearfix 
 .post_image_description 
 = image_tag @ post.image.url（ ：中）
 .description = simple_format（@ post.address）
 .description = simple_format（@ post.description）
  

不应该 @ post.image.url 足够吗？我可能错过了什么可以正确路由到图像？

这是我看到当我拉 Heroku Logs ：

  2015-06-23T15：38：26.181383 + 00：00 app [web.1]：ActionController :: RoutingError（没有路线匹配[GET]/images/medium/missing.png）：
  

这里是我的项目存储库： https://github.com/lucasvocos/pitstop

请让我知道是否还有其他问题需要提供。因为这是我第一次问。谢谢大家。

解决方案

我有一个类似的问题，上传工作正常，但显示屏显示链接已断开。我检查了链接的源代码，它没有指向S3上显示的图像的URL。我不得不将主机名添加到我的回形针配置中。

  config.paperclip_defaults = {
：storage => ：s3，
：s3_host_name => 's3-us-west-2.amazonaws.com'，
：s3_credentials => {
：bucket => ENV ['S3_BUCKET_NAME']，
：access_key_id => ENV ['AWS_ACCESS_KEY_ID']，
：secret_access_key => ENV ['AWS_SECRET_ACCESS_KEY'] 
} 
} 
  

Long time viewer, first time asker. I've searched for this topic but don't believe I've found the answer.

I have a Post model that has an image. I'm using the Paperclip gem, saving to Amazon S3, and hosting on Heroku.

The file upload form works fine, because I can see that images are sent to my S3 bucket.

The issue is that, the images don't actually show in production.

Here's my model:

class Post < ActiveRecord::Base
    attr_accessor :image_file_name, :image_content_type, :image_file_size, :image_updated_at
    belongs_to :user
    has_many :reviews

    has_attached_file :image, styles: { medium: "700x500#", small: "350x250>" }
    validates_attachment_content_type :image, content_type: /\Aimage\/.*\Z/

And here's my config/production.rb:

# Required for Paperclip / AWS
config.paperclip_defaults = {
:storage => :s3,
:s3_credentials => {
    :bucket => ENV['S3_BUCKET_NAME'],
    :access_key_id => ENV['AWS_ACCESS_KEY_ID'],
    :secret_access_key => ENV['AWS_SECRET_ACCESS_KEY']
    }
}

And here's my show.html.haml file:

.clearfix
    .post_image_description
        = image_tag @post.image.url(:medium)
        .description= simple_format(@post.address)
        .description= simple_format(@post.description)

Shouldn't the @post.image.url be enough? What may I be missing to properly route to the image?

This is what I see when I pull Heroku Logs:

2015-06-23T15:38:26.181383+00:00 app[web.1]: ActionController::RoutingError (No route matches [GET] "/images/medium/missing.png"):

For reference, here's my repository for the project: https://github.com/lucasvocos/pitstop

Please let me know if there is anything else to provide in the question, too. As this is my first time asking. Thanks everyone.

解决方案

I had a similar problem that the upload was working but the display was showing a broken link. I checked the source for the link and it was not pointing to the url shown for the image on S3. I had to add the host name to my paperclip config

  config.paperclip_defaults = {
  :storage => :s3,
  :s3_host_name => 's3-us-west-2.amazonaws.com',
  :s3_credentials => {
    :bucket => ENV['S3_BUCKET_NAME'],
    :access_key_id => ENV['AWS_ACCESS_KEY_ID'],
    :secret_access_key => ENV['AWS_SECRET_ACCESS_KEY']
  }
  }
