i would like to create a Rails controller that download a serie of jpg files from the web and directly write them into database as binary (I am not trying to do an upload form)
Any clue on the way to do that ?
Thank you
Edit : Here is some code I already wrote using attachment-fu gem :
http = Net::HTTP.new('awebsite', 443) http.use_ssl = true http.verify_mode = OpenSSL::SSL::VERIFY_NONE http.start() { |http| req = Net::HTTP::Get.new("image.jpg") req.basic_auth login, password response = http.request(req) attachment = Attachment.new(:uploaded_data => response.body) attachement.save }
And I get an "undefined method `content_type' for #" error
Use open-url (in the Ruby stdlib) to grab the files, then use a gem like paperclip to store them in the db as attachments to your models.
UPDATE:
Attachment_fu does not accept the raw bytes, it needs a "file-like" object. Use this example of a LocalFile along with the code below to dump the image into a temp file then send that to your model.
http = Net::HTTP.new('www.google.com') http.start() { |http| req = Net::HTTP::Get.new("/intl/en_ALL/images/srpr/logo1w.png") response = http.request(req) tempfile = Tempfile.new('logo1w.png') File.open(tempfile.path,'w') do |f| f.write response.body end attachment = Attachment.new(:uploaded_data => LocalFile.new(tempfile.path)) attachement.save }
