I have a problem with the path. In my model I have following setup:
class Pdffiles < ActiveRecord::Base
belongs_to :user
has_attached_file :invoice_file,
:path => ":rails_root/public/pdffiles/:user_id/:style/:basename.:extension",
:url => "/pdffiles/:user_id/:style/:basename.:extension",
:storage => :s3,
:bucket => '...',
:s3_credentials => {
:access_key_id => '...',
:secret_access_key => '...'
}
end
and in a controller looks my action this:
pdf = Prawn::Document.new
pdf.move_down 70
pdf.text("Prawn Rocks")
pdf.render_file('prawn.pdf')
pdf_file = File.open('prawn.pdf')
pdff = Pdffile.new()
pdff.pdffile_file = pdf_file
pdff.user_id = todays_user.id
pdff.save
And my problem is, that this PDF file is stored to the S3 server, but on the bad place. Instead the directory app/public/pdff/id_of_a_user/file_name_of_pdf_file is the file saved to
Users/my_name/my_ruby_root_directory/name_of_my_project/public/pdffiles/id_of_a_user/file_name_of_pdf_file.
I am not totally sure, if I use the prawn for saving PDF files right, but I think the problem could be in the controller, where I have set up the place, where the created file have to be saved...
I would like to ask you, what I should change for saving PDF files into the right directory in S3... All helps will be appreciated!
Manny thanks, Sep
You could use something like CarrierWave ( https://github.com/jnicklas/carrierwave ) -- it makes uploading to S3 extremely easy with the FOG library https://github.com/jnicklas/carrierwave
The Users/my_name/my_ruby_root_directory/name_of_my_project/public portion of the path came from :rails_root/public portion of the path you configured in paperclip. So if you really want the s3 "directory" to be app/public/pdff/id_of_a_user/file_name_of_pdf_file you need to give paperclip the following path: app/public/pdffiles/:user_id/:style/:basename.:extension
Also, according to your model, you should use pdff.invoice_file = pdf_file instead of pdff.pdffile_file = pdf_file
I hope this helps.

I have a set of images on Amazon S3, and I'd like to automatically generate thumbnails for them to serve on my site.
I've considered Cloudinary, but it seems that I'd have to copy over all my images to Cloudinary servers first. I want to keep them on S3.
I've considered Dragonfly, but it seems that Dragonfly only works with files I'd upload after installing Dragonfly. I already have uploaded all my files.
What's a good solution for me? I'm in a Rails environment (rails 3.2).
Thanks!
If it's just a 'set of images' it's not really that well structured. You're better off reorganizing the way you store and manage images.
Try Paperclip.
class ModelName < ActiveRecord::Base
attr_accessible :image #more here
has_attached_file :image, :styles => { :large => "450x450>", :medium => "300x300>", :thumb => "150x150>" },
:storage => :s3,
:s3_credentials => "#{Rails.root}/config/s3.yml",
:path => "people/:style/:id/:filename",
:s3_protocol => "https"
def original_image_url
image.url
end
def large_image_url
image.url(:large)
end
def medium_image_url
image.url(:medium)
end
def small_image_url
image.url(:thumb)
end
#etc
end
Then simply do this to assign an existing image to an existing instance through the console:
require 'uri'
#instance.image = open(URI::encode(url))
#instance.save
# s3 will now contain the images in the appropriate sizes in the format specified above.
Since the original will also be saved, I'd advise to then delete the 'set of images' on s3 you started with, otherwise you'll be duplicating them.
I was wrong about Dragonfly. You can use Dragonfly on already-uploaded files. I'm using it on my project and it's working out great.
I have a model called Picture with an attached file on it.
the software I am using:
*Rails 3
*Ruby 1.9.3
*Paperclip
*ImageMagick
My model is:
class Picture < ActiveRecord::Base
attr_accessible :picturefile,:picturefile_file_name,:picturefile_content_type,:picturefile_file_size,:picturefile_updated_at
has_attached_file :picturefile,
:styles => {
:thumb=> "100x100#"},
:storage => :s3,
:s3_credentials => Rails.root.join('config','s3.yml'),
:path => "/travels/:style/:id/:basename.:extension"
end
And in my controller I have this:
StringIO.open(Base64.decode64(params[:Route][:CoverPicture][:File][:EncodedContent])) do |data|
fotocov_t=Picture.create({
:picturefile=>data
})
travel.pictures = [fotocov_t] #this assigns the new picture to a travel i created before the picture
end
As it can be seen i am uploading a string, but what I want to upload is an image that is made by the encoded string in
params[:Route][:CoverPicture][:File][:EncodedContent]
I have tried with multiple aproaches but keeps saving a text file.
Does anyone know how I can upload the file as an image instead of uploading a textfile?
Thank you :)
Found it :)
bytes = Base64.decode64(params[:Route][:CoverPicture][:File][:EncodedContent])
img = Magick::Image.from_blob(bytes).first
On record creation:
:picturefile=>img
Needed rmagick.
Now I have another trouble with No handler for...
But will be searching and uploading info :)
I have application which is deployed to heroku using amazon s3 posting images to buckets.This works perfectly fine. But when fetching same image it gives error:
Errno::ENOENT (No such file or directory showing path s3.amazonaws.com/bucket_name/app/public/messages/images/000/000/061/thumb/images.jpeg?1362410115)
Same path copying and pasting in browser's url doesn't work. If I am using bucket name as end point it works ie, with following path
/bucket_name.s3.amazonaws.com/app/public/messages/images/000/000/061/thumb/images.jpeg?1362410115.
But I dont know how to configure this url in my model. I am following heroku's way to configure aws-sdk.
https://devcenter.heroku.com/articles/paperclip-s3
Model has_attached_file seems like i am missing something here.For rest of configuration you can check above link.
has_attached_file :image, :styles => { :medium => "100x100>", :thumb => "100x100>" }
Thanks
Including given code in config/initializers/paper_clip.rb resolved my problem.
Paperclip::Attachment.default_options.merge!(
:url => ':s3_domain_url',
:path => 'app/public/:class/:attachment/:id_partition/:style/:filename'
)
I've just upgraded from Rails 3.1 to Rails 3.2.6 and my paperclip photo paths are now broken on production.
photo.rb
if Rails.env == "production"
has_attached_file :image,
:storage => :s3,
:s3_credentials => S3_CREDENTIALS,
:url => "/app/public/system/images/:id/:style/:basename.:extension",
I need the resulting path to be like so: http://s3.amazonaws.com/photoramblr/app/public/system/images/5/thumb_large/image.jpg
but instead the above url settings result in: http://s3.amazonaws.com/photoramblr/app/public/app/public/system/images/5/thumb_large/image.jpg
I've also tried setting the paperclip url to :url => "/system/images/:id/:style/:basename.:extension" but that resulted in this url: http://s3.amazonaws.com/photoramblr/images/5/thumb_large/image.jpg
Any thoughts on how I can set this properly?
UPDATE: Well, I still don't understand how it's working, but I 'fixed' this by just moving the files to the location it was looking in.
Try adding a path parameter replacing the url parameter and specifying the path under the bucket name where your file will be stored and the URL will be constructed from the bucket and the path supplied. Here is a link to paperclip s3 docs for further details. If you supply a url parameter, it is treated relative to your "app/public". That explains why you're resulting image path doubles "app/public". Ryan Bate's paperclip tutorial also explains this behaviour.
In your case your code will be as shown below;
if Rails.env.production?
has_attached_file :image,
:storage => :s3,
:s3_credentials => S3_CREDENTIALS,
:path => "app/public/system/images/:id/:style/:basename.:extension",
Your resulting link will be (I'm assuming your bucket name is photorambler from your link); s3.amazonaws.com/photorambler/app/public/system/images/5/thumb_large/image.jpg
I am new to rails and paperclip plugin - so I apologize if this is as a silly question.
I am trying to upload a file and later access the url for the file url. In dev, the file gets stored locally while in prod, the file is pushed to s3.
Once the model is stored in the db, how to I get the url later on to display the link?
When you specify a paperclip association in a model you do :
class ModelName < ActiveRecord::Base
has_attached_file :thumbnail, :styles => { :medium => "300x300#", :thumb => "100x100#"} , :default_url => '/images/default/missing.png'
end
To get the url, you have to do :
#model.thumbnail.url(:original)
Where :original is the file format, it can be :medium, :thumb...
