Refinery CMS - How to resize a resource image?

I have a TestimonialResource model which has a resource field type. The backend works okay where I am able to pick a file to upload as a resource to the testimonial.

However, I am unable to generate a thumbnail of the resource(if it is an image). I know it works with an image field type and have done it in the past.

I have also looked at the available methods in the Rails console and it does list thumb as a method.

However, the following does not work in the front-end view.

<%= testimonial_resource.content.thumb('400x400#').url %>

Content is the RefineryCMS resource.

Can someone point me in the right direction?

Dragonfly stores an image once and produces image variations (thumbnails, formats and enhancements) on-the-fly.

So, all related methods are available only to the image model. That means you can't run those methods on everything, but you have a link or local address to the image. So, you can always build a thumb manually:

require "mini_magick"

image = MiniMagick::Image.open("input.jpg")
image.resize "400x400"
image.format "png"
image.write "output.png"

For the existing image object:

image.thumbnail(:geometry => '400x400#c').url
