Instance Method Details

#extension_whitelist ⇒ Object

Override this method in your uploader to provide a white list of extensions which are allowed to be uploaded. Compares the file's extension case insensitive. Furthermore, not only strings but Regexp are allowed as well.

When using a Regexp in the white list, \A and \z are automatically added to the Regexp expression, also case insensitive.

=== Returns

[NilClass, String, Regexp, Array[String, Regexp]] a white list of extensions which are allowed to be uploaded

=== Examples

def extension_whitelist
  %w(jpg jpeg gif png)
end

Basically the same, but using a Regexp:

def extension_whitelist
  [/jpe?g/, 'gif', 'png']
end
