Get Full URL for ActiveStorage image

The following will return a URL that will work, but is there a better method that doesn't require the concatenation of strings? I do not want to expose the service_url since that URL expires. 

 root_url + url_for(object.image.variant(resize: '140x140'))

Ultimately, I would like to do something like this 

object.image.variant(resize: '140x140').absolute_url
Solution

  • I'm not sure if this is the recommended way, but you can use the polymorphic_url helper:

    polymorphic_url object.image.variant(resize: '140x140')
