#extension_white_list ⇒ Object

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



80
81
82
 
# File 'app/uploaders/crimagify/image_uploader.rb', line 80

def extension_white_list
  %w(jpg jpeg gif png)
end

#store_dir ⇒ Object

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



18
19
20
 
# File 'app/uploaders/crimagify/image_uploader.rb', line 18

def store_dir
  "uploads/#{model.class.to_s.underscore}/#{mounted_as}/#{model.id}"      
end
