我正在创建一个Rails应用程序,用户使用Paperclip将文件上传到S3,然后一个单独的组可以下载上传的文件。我需要这些文件是私有的并且一直在尝试使用:permissions => :私有没有任何运气,但可以在关闭时上传和下载文件。
我一直在关注github问题:https://github.com/thoughtbot/paperclip/wiki/Restricting-Access-to-Objects-Stored-on-Amazon-S3和Rails 3, paperclip + S3 - Howto Store for an Instance and Protect Access但我仍然感到困惑并希望得到一些帮助。以下是我到目前为止的情况:
模型/ user.rb
class User < ActiveRecord::Base
has_many :parts
...
if Rails.env.development?
has_attached_file :model
else
has_attached_file :model,
:storage => :s3,
:path => "files/:id/:basename.:extension",
:default_url => '/images/missing_:style.jpg',
:bucket => ENV['AWS_BUCKET'],
:s3_permissions => :private,
:s3_host_name => 's3-us-west-1.amazonaws.com',
:s3_credentials => {
:access_key_id => ENV['AWS_ACCESS_KEY_ID'],
:secret_access_key => ENV['AWS_SECRET_ACCESS_KEY']
}
end
user_controller.rb
def create
@user = User.new(params[:user])
@part = Part.new
if @user.save
...
end
end
def download
@user = User.find(params[:id])
redirect_to(@user.model.expiring_url(10))
end
part_controller.rb
class PartsController < ApplicationController
def index
@parts = Part.all
@users = User.all
end
end
的routes.rb
match 'users/download' => 'users#download', :as => 'download_model'
份/ index.html.erb
<p>
<% @parts.each do |part| %>
<p><%= part.model_name %></p>
<% end %>
<% @users.each do |user| %>
<p><%= link_to "Download", download_model_path(user) %></p>
<% end %>
</p>
