问题 I am trying to create a functional test for paperclip 3.1.2 on rails 3.2.6 using FactoryGirl 3.0 and when i pass the file attachment my controller receives a string which is the file location and not the Paperclip::Attachment object. My factory is: include ActionDispatch::TestProcess FactoryGirl.define do factory :artist do id 1 name 'MyString' photo {fixture_file_upload("#{Rails.root}/test/fixtures/files/rails.png",'image/png')} end end And my test is: test "should create artist" do assert

问题 I'm inserting a digital signature into a pdf file inside my processor, but keep getting an AWS::S3::ERRORS::Requestimeout error. What is this timeout? Is there any way i could keep the connection open until the file gets uploaded ? Your socket connection to the server was not read from or written to within the timeout period. Idle connections will be closed. Here is my code : model: ... has_attached_file :receipt_file, :storage => :s3, :s3_credentials => "#{Rails.root}/config/s3.yml", :path =

问题 I would like to use paperclip to upload files. With the basic out of the box settings, I was able to get the file uploaded to the default directory (something in public/systems...) However when I tried changing the url or path (or both): class Cvit < ActiveRecord::Base has_attached_file :fileup, :path => ":rails_root/public/data/01_fasta" end I lose permission to the 01_fasta directory, after doing a chmod 777 on it, I notice the file is there but its named something like, stream20110706

问题 We're using Paperclip with the aws-sdk gem to store and display images in our Rails app: class User < ActiveRecord::Base has_attached_file :image, storage: :s3, s3_credentials: 'config/s3.yml', s3_protocol: :https, styles: { curriculum: '120x120>', medium: '600x600>', thumb: '200x200>' }, default_url: 'missing_photo.png' end If I then use <%= image_tag current_user.image.url %> in an html.erb file, I get the following HTML: <img src="https://s3.amazonaws.com/<my_bucket>/users/images/000/000

问题 My application is using Rails 2 backend, Heroku for hosting, Paperclip for file uploads, and Amazon S3 for file storage. Right now users can upload files with paperclip + s3 - this works flawlessly. After upload, an icon appears on their dashboard, linked to the file location (in s3 bucket).
