Re: [Rails] Rails 5.2 Active storage Unable to autoload constant ActiveStorage::Blob::Analyzable

Ruby on Rails Tuesday, June 12, 2018

Hi Frantz

I have an issue similar to Mattia's, so I tried your suggestion.
Thanks for the advice, although installing mini_magick (v4.8) didn't solve the issue for me.

For context, I'm on ruby 2.4.2 / rails 5.2 / active storage 5.2
I followed this tutorial for the active storage setup

I tried to upload via a form and to directly attach a local file to an existing object in the rails console.
Strangely enough I have a first `NoMethodError: undefined method `[]' for nil:NilClass` when trying the first time, 
and the `Unable to autoload constant ActiveStorage::Blob::Analyzable` error the second time.

The full session log if it helps:

I've updated rails from 5.1.4 to 5.2 and remove Papaerclip to use Active Storage. I'm using digitalocean spaces. In my development env I've setted credentials in storage.yml to save images to digitalocean.

I've added aws gem in gemfile. I run db:migrate for active storage.

But when I'm going to submit the form with an image upload html tag, i receive this error: Unable to autoload constant ActiveStorage::Blob::Analyzable.

Anyone can help me?

Thanks in advance.
