Unable to display image using variant with ActiveStorage image_processing gem

Currently I'm working on a Rails 5.2 application. When I try to display a profile's avatar in a show.html.erb template using variant it doesn't work

<%= image_tag @profile.avatar.variant(resize_to_fit: [100, 100]) %>

I get the followingenter image description here

I'm unable to see the image.

I installed gem 'image_processing', '~> 1.2' in my Gemfile.

Also on application.rb I added config.active_storage.variant_processor = :vips

But still, on the backend I get a 500 error:

Started GET "/rails/active_storage/representations/xxxx/steven.jpeg" for 127.0.0.1 at 2018-09-26 16:33:21 -0400

Completed 500 Internal Server Error in 3ms (ActiveRecord: 0.3ms)

If I edit to <%= image_tag @profile.avatar %> I'm able to see the original image.

here is the Photo model:

 class Profile < ApplicationRecord
  belongs_to :user
  has_one_attached :avatar
 end

Any suggestions?

The image_processing gem relies on ImageMagick to do the actual image transformation. ImageMagick isn’t a Ruby gem; it’s distributed as a binary that’s specific to your operating system. You’ll need to install it separately for your operating system: For Linux use apt-get:

sudo apt-get install imagemagick

Then once you have ImageMagick installed, you’ll need to restart your Rails app.

The version of Rails you are using is 5.2, ActiveStorage of the version has no variant_processor option.

resize_to_fit is the option belongs to image_processing. You install the gem, but the processor is fixed to mini_magick. see: https://github.com/rails/rails/blob/v5.2.3/activestorage/app/models/active_storage/variant.rb#L117

If you want to keep the version of 5.2, you should follow options provided by mini_magick. see: https://api.rubyonrails.org/classes/ActiveStorage/Variation.html

If you prefer to use image_processing to enjoy convenient options, you should upgrade your Rails version to >= 6.

try this:

<%= image_tag @profile.avatar.variant(resize: "100x100") %>
