module Shrine::Plugins::DefaultUrl

  1. lib/shrine/plugins/default_url.rb

The default_url plugin allows setting the URL which will be returned when the attachment is missing.

plugin :default_url

Attacher.default_url do |options|

Attacher#url returns the default URL when attachment is missing. Any passed in URL options will be present in the options hash.

attacher.url #=> "/avatar/missing.jpg"
# or
user.avatar_url #=> "/avatar/missing.jpg"

The default URL block is evaluated in the context of an instance of Shrine::Attacher.

Attacher.default_url do |options|
  self #=> #<Shrine::Attacher>

  name   #=> :avatar
  record #=> #<User>
