I have a project I'm trying to use ruby 3 (previously running with 2.7.2), but couldn't accomplish it.

I'm trying to revive an old Rails application I worked on several years ago. I'm using ruby 2.3.3 and rails 3.2.15 on the Heroku-16 stack with ClearDB for my MySQL database with the mysql2 adapter. When deploying to Heroku it succeeds on the deploy but crashes when it tries to start the app.

Full stack trace from the Heroku log (updated after fixing activerecord-import gem version per suggestion in first answer):

I am trying to run a single test file: bundle exec rspec spec/models/user_spec.rb

I am trying to create a simple Rock, Paper, Scissors game to practice some basic Python skills. I created the code below to take user input and create a simple point-based game. However, when I ran the code, the loop ran infinitely, printing the output message until I force stopped it. How can I alter my code so the while-loop only runs once per user input?

Hi guys Can I please get some help to figure out what is going wrong with my RSpec test. I been looking all over the internet and haven't found anything that would point to reason why i'm getting this error.

What i'm trying to do is test that an instance variable has some data from the DB. The error is happening when the test reaches the Fabricator that creates the active record and also the ActiveStorage Blob. I have added the database-cleaner gem but not sure of something is messing up with that or i'm missing something when using RSpec, active storage, and DBcleaner.

What is strange is that I have another test that also creates the same Fabricated Object and I dont get the error you will see below. If I comment out the test below the other test runs just fine. Any help would be really appreciated. Been stuck on this for hours :$

UPDATE: I tried to look into what was happening after the graphic fabricator ran and when I looked into the attachments using the attached? methods each of the files were actually attached. All four files came back as attached true. I thought there would be something going on with the cleaner so I added to the rails_helper to purge all the files after each test is done.

I got NameError: uninitialized constant Capistrano::Puma with this Gemfile:
