#default_url(*args) ⇒ Object

Provide a default URL as a default if there hasn’t been a file uploaded: def default_url

# For Rails 3.1+ asset pipeline compatibility:
# asset_path("fallback/" + [version_name, "default.png"].compact.join('_'))

"/images/fallback/" + [version_name, "default.png"].compact.join('_')

end

#filename ⇒ Object

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

#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: def store_dir

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