How to save a raw_data photo using paperclip

Question

I\'m using jpegcam to allow a user to take a webcam photo to set as their profile photo. This library ends up posting the raw data to the sever which I get in my rails contr

The problem with my previous solution was that the temp file was already closed and therefore could not be used by Paperclip anymore. The solution below works for me. It's IMO the cleanest way and (as per documentation) ensures your tempfiles are deleted after use.

Add the following method to your User model:

def set_picture(data)
  temp_file = Tempfile.new(['temp', '.jpg'], :encoding => 'ascii-8bit')

  begin
    temp_file.write(data)
    self.picture = temp_file # assumes has_attached_file :picture
  ensure
    temp_file.close
    temp_file.unlink
  end
end

Controller:

current_user.set_picture(request.raw_post)
current_user.save

Don't forget to add require 'tempfile' at the top of your User model file.
