paperclip

has_attached_file :image, :storage => :s3, :s3_credentials => "#{RAILS_ROOT}/config/s3.yml", :path => "/:style/:filename" I'm not sure what :path => "/:style/:filename" is. I also want to to include the style for this attached image, is that what the :path is? the style I want is this: :styles => { :medium => "275x275>", :thumb => "175x155>" } Basically what's going on here is that I'm setting up on heroku and I'm having to use S3 which seems straightforward just not used to this attachment convention stuff. Also, I just signed up for an S3 account... but heroku was spouting that its free or

I'm using: Paperclip 2.3.16 Rails 3.0.9 Ruby 1.9.2 AWS - S3 0.6.2 I'm trying to use paperclip the upload to the EU (Ireland) based bucket. I have the following in my model: has_attached_file :image, :styles => { :grid => '90x128#', :list => '140x200#', :original => '400x548'}, :storage => :s3, :s3_credentials => "#{RAILS_ROOT}/config/s3.yml", :url => 'flyers/:id/:style/:basename.:extension', :path => 'flyers/:id/:style/:basename.:extension', :bucket => 'fsight' In my environment.rb I have set the write to use the AWS/s3 Default Host to the relevant EU one by using: require "aws/s3" AWS::S3:

Is it possible to get the absolute URI for a Paperclip attachment? Right now, the problem is that the production environment is deployed in a sub-URI (on Passenger: RackBaseURI ), but <paperclip attachment>.url returns the Rails-app relative URI ( /system/images/... ). Is there a way to get the absolute URI for Paperclip attachments? I'm using Paperclip v2.7 and Rails 3.2.8. kuboon try URI.join(request.url, @model.attachment_name.url) or URI(request.url) + @model.attachment_name.url It's safe if you use S3 or absolute url.

I use this method for renaming the image before the saving: def rename_avatar self.avatar.instance_write :file_name, Time.now.to_i.to_s end before_post_process :rename_avatar The image is renamed by the current time, but there's not added the file type, instead of 1334487964.jpg is saved only 1334487964. . What I missing there? I thought :file_name contains only the file name - without the file type This is the way how I fix my issue: def rename_avatar #avatar_file_name - important is the first word - avatar - depends on your column in DB table extension = File.extname(avatar_file_name)

Trying to get the width and height of the uploaded image while still in the model on the initial save. Any way to do this? Here's the snippet of code I've been testing with from my model. Of course it fails on "instance.photo_width". has_attached_file :photo, :styles => { :original => "634x471>", :thumb => Proc.new { |instance| ratio = instance.photo_width/instance.photo_height min_width = 142 min_height = 119 if ratio > 1 final_height = min_height final_width = final_height * ratio else final_width = min_width final_height = final_width * ratio end "#{final_width}x#{final_height}" } },

So, I want to resize images to a FIXED width, but proportional height. I have been trying a wide range of operators: 380x242# 380x242> 380!x242 380x242< none of them have the desired effect. Any help? I want it to fill or resize to the 380 width, then resize / shrink the height by the same factor it used to shrink or resize the image to 380 wide. Try using 380x This should resize width to 380px and keep original aspect ratio.
