amazon-web-services - 如何在 heroku 上正确配置 Rails 5、paperclip 5、aws-sdk 2？

Question

我在本地部署了带有回形针附件的 Rails 5 应用程序:一切正常。仅在 heroku 上我需要 AWS s3，它不适用于 Rails 5.0.1/paperclip 5.1.0/aws-sdk 2.7.3。

有人有在 s3 上存储附件的有效配置吗？

这是我的模型/article.rb:

class Article < ApplicationRecord
  has_many :comments, dependent: :destroy
  validates :title, presence: true,
                length: { minimum: 5 }
  has_attached_file :attachment,
            :url => ":s3_domain_url",
            #:path => ':filename',
            :storage => :s3,
            :bucket => ENV['AWS_BUCKET'],
            :s3_bucket => ENV['AWS_BUCKET'],
            :s3_permissions => :private,
            :s3_protocol => 'http',
            :s3_host_name => 's3.amazonaws.com',
            #:s3_host_alias => 's3.amazonaws.com',
            :s3_region => ENV['AWS_REGION'],
            #:region => ENV['AWS_REGION'],
            :s3_credentials => { :access_key_id => ENV['AWS_ACCESS_KEY_ID'],
                                 :secret_access_key => ENV['AWS_SECRET_KEY_ID'],
                                 :endpoint => 's3.amazonaws.com' }

  # Explicitly do not validate
  do_not_validate_attachment_file_type :attachment
  #validates_attachment :attachment, content_type: { content_type: 'application/x-java-archive'}, size: { in: 0..10.megabytes }
end

环境变量设置为:

AWS_ACCESS_KEY_ID=....
AWS_BUCKET=....
AWS_REGION=us-east-1
AWS_SECRET_KEY_ID=....

articles_controller 是:

class ArticlesController < ApplicationController

  http_basic_authenticate_with name: "gerrit", password: "_tVo1I44iyLe", except: [:index, :show]

  def index
    @articles = Article.all
  end

  def show
    @article = Article.find(params[:id])
  end



def new
  @article = Article.new
end

def edit
  @article = Article.find(params[:id])
end

def create
  @article = Article.new(article_params)

  if @article.save
    redirect_to @article
  else
    render 'new'
  end
end

def update
  @article = Article.find(params[:id])

  if @article.update(article_params)
    redirect_to @article
  else
    render 'edit'
  end
end

def destroy
  @article = Article.find(params[:id])
  @article.destroy

  redirect_to articles_path
end

private
  def article_params
    #article_params =
    params.require(:article).permit(:title, :text, :attachment)
    #@article.update_attributes( article_params )
  end
end

这是我现在在本地和 heroku 上遇到的错误，之前还有很多其他错误:

未初始化常量 Paperclip::Storage::S3::AWS提取的源代码(大约第 26 行):

  @article = Article.new(article_params)

  if @article.save #line 26
    redirect_to @article
  else
    render 'new'

参数:

{"utf8"=>"✓", "authenticity_token"=>"snGgVwA5tqQTPHXwXW1Fx/lmLMS1bL+94jF68KQh031gpX2N78gOK45hCP8w71ObFo6moHQuJXxNnUW0bCUeVw==",
 "article"=>
  {"title"=>"test1",
   "text"=>"",
   "attachment"=>
    #<ActionDispatch::Http::UploadedFile:0x007f46c00881e0
     @content_type="application/x-desktop",
     @headers="Content-Disposition: form-data; name=\"article[attachment]\"; filename=\"Antichamber.desktop\"\r\n" + "Content-Type: application/x-desktop\r\n",
     @original_filename="Antichamber.desktop",
     @tempfile=#<File:/tmp/RackMultipart20170306-5350-esbhtd.desktop>>},
 "commit"=>"Create Article"}

为了方便，我在此处添加了损坏的 Rails 5 应用程序的 URL:

gmr-heroku

现在一切正常!

注意:您希望我提出不同的问题，而不是添加到原始问题中。现在您不想要重复的答案。

Answer 1

:url => :s3_domain_url 应该是 :url => ":s3_domain_url"
