FotoUploader

Add a white list of extensions which are allowed to be uploaded. For images you might use something like this:

# File app/uploaders/foto_uploader.rb, line 57
def extension_white_list
  %(jpg jpeg gif png)
end

Override the directory where uploaded files will be stored. This is a sensible default for uploaders that are meant to be mounted:

# File app/uploaders/foto_uploader.rb, line 14
def store_dir
  "uploads/#{model.class.to_s.underscore}/#{mounted_as}/#{model.id}"
end

Override the filename of the uploaded files: Avoid using model.id or version_name here, see uploader/store.rb for details. def filename

"something.jpg" if original_filename

end

# File app/uploaders/foto_uploader.rb, line 67
def store_exif
  img = Magick::Image.read(current_path)
  model.exif=img.first.get_exif_by_entry().to_json
  
end
