paperclip

问题 I'm able to upload my images however, when I try to upload videos it posts as a black screen with a play button that does not work. I'm not sure where I went wrong. Do I need a video player in order for this to work? This may be an easy solution however, I'm new to Rails. Any help is greatly appreciated. Thank you. Post Model class Post < ActiveRecord::Base belongs_to :user has_attached_file :image, :styles => { :medium => "300x300>", :thumb => "100x100>" } has_attached_file :video, :styles =

问题 I am very new to Rails, I am running Rails 3 I recently installed ImageMagick via Homebrew and then ran 'sudo plugin install git://github.com/thoughtbot/paperclip.git' I added "gem 'rmagick'" to my root Gemfile. Immediately after doing so I found that no rails commands worked anymore (error below). I tried adding "config.gem "rmagick", :lib => "RMagick"" to my environment.rb as some other threads suggested, but this returns a different error (undefined local variable or method `config' for

问题 I'm working on a rails web application. Just created and prepared some models and stuff. The application is very simple. But now I have a problem by setting up the gem paperclip to add attachments to a model. Almost everything works fine, like attaching images/jpg or even pdf. But I can't upload zip files. I tried different zip files, but I'm always getting: "Attachment Paperclip::Errors::NotIdentifiedByImageMagickError" This is my model: class Order < ActiveRecord::Base has_attached_file

问题 I'm trying to use Amazon S3 for Paperclip attachments. First, I'm trying to get it to work in development environment on my iMac. I have created the Amazon buckets = ndeavor-dev and ndeavor-pro. In the code below, I have substituted the bucket name and keys. I have the gem's paperclip and aws-sdk . The error I get is: ArgumentError at /attachments missing required :bucket option I have tried this in my config/environments/development.rb: config.paperclip_defaults = { :storage => :s3, :s3

问题 I have a model with paperclip ruby gem. I defined an attached file with 2 processors ( thumbnail and watermark ). The question is if exist the way to apply the watermark processor if condition is true . (the idea it's not define new attached_files without watermark processor) Thanks in advance. I try using this code, but dosen't works. If the field eid exist process with watermark else if null process only thumbnail :processors => lambda { |a| if a.eid.nil? [:thumbnail,:watermark] else [

问题 I'm trying to save images via a form that populates a "Select" field with a number of options. The select form uses Image Picker to change the options when an user clicks on a selected image. When the form is submitted, the selected image should be saved with the Paperclip gem. I think I just need to point the image url from the selected option to a method that will open it in Paperclip, but I'm not quite sure how to do that. I'm new to Rails, and humbly appreciate anything that will point me

问题 I have tried many different ways to set up S3 using ENV variables for image uploads and cannot get it to work. I know my keys and bucket name work, because when I put them straight into the code, my images upload correctly. However, when I try to switch to ENV variables, things do not work. I used the figaro gem, which created application.yml. In that file, I have: S3_BUCKET_NAME "xxxxx" AWS_ACCESS_KEY_ID: "AAAAAAAAA" AWS_SECRET_ACCESS_KEY: "BBBbbbBBBB" Not sure if there should be any

问题 I have my app running on heroku and have configured to save all assets uploaded to a bucket using Amazon s3.That all works fine. So when i tried to upload an image locally (development) i get the following error AWS::S3::Errors::PermanentRedirect in RecipesController#update The bucket you are attempting to access must be addressed using the specified endpoint. Please send all future requests to this endpoint. My update action def update @recipe = Recipe.find(params[:id]) if @recipe.update

问题 I'm trying to upload a file to s3 using paperclip and get this error when making a new object and referencing the variable: the aws-s3 gem is installed the s3.yml file has the correct credentials ie: a = Attachment.new a.file NameError: uninitialized constant AWS::S3::Connection from /Library/Ruby/Gems/1.8/gems/aws-s3-0.6.2/lib/aws/s3/extensions.rb:206:in `const_missing' from /Library/Ruby/Gems/1.8/gems/aws-s3-0.6.2/lib/aws/s3.rb:32 from /Library/Ruby/Gems/1.8/gems/aws-s3-0.6.2/lib/aws/s3.rb

问题 Paperclip has validator methods for validating the presence, size, and content-type of files. But is there a way to validate the contents of the file before the record is saved? I tried doing validate :my_method and opening the file from [attachment].path in my_method , but of course that fails because the attachment hasn't been moved to its final resting place in the file system before the record is saved. Writing a custom Paperclip post-processor seemed like an option because it has access
