Class Method Details

.to_detect_type_by(name, &block) ⇒ Object

Register a custom type detector.

When instantiating an attachment, Bulldog will use the configured type detector to work out which type of attachment to use. This method registers a custom type detector which may be selected in your attachment configuration by just using the name.

The given block is passed the record, the attribute name, and the value as a Bulldog::Stream. The block should return a symbol representing the attachment type.

Example:

Bulldog.to_detect_type_by :file_extension do |record, name, stream|
  case File.extname(stream.file_name).sub(/\A\./)
  when 'jpg', 'png', 'gif', 'tiff'
    :image
  when 'mpg', 'avi', 'ogv'
    :video
  when 'pdf'
    :pdf
  end
end

  Reflection.to_detect_type_by(name, &block)
end

.to_interpolate(token, &block) ⇒ Object

Define an interpolation token.

If :<token> appears in a path or URL template, the block will be called to get the value to substitute in. The block will be called with 3 arguments: the record, the attachment name, and the style.

Example:

Bulldog.to_interpolate :datestamp do |record, name, style|
  Date.today.strftime("%Y%m%d")
end
