ActiveRecord::AssociationTypeMismatch after migrate from Jets 3 to 5

Hello there!

After upgrading my Jets application from version 3 to 5, I encountered some flaky specs. When running the entire spec suite, numerous errors are raised, with most of them being ActiveRecord::AssociationTypeMismatch errors. However, when I isolate and run one of these failing specs, it works perfectly fine.

Upon analysis, it seems that the failed specs might be related to a database problem.

Here’s how my spec_helper.rb file looks:

ENV['JETS_TEST'] = '1'
ENV['JETS_ENV'] ||= 'test'

require 'simplecov'
SimpleCov.start do
  add_group 'Models', 'app/models'
  add_group 'Controllers', 'app/controllers'
  add_group 'Jobs', 'app/jobs'
  add_group 'Services', 'app/services'
  add_group 'lib', 'lib'

  changed_files = `git diff --name-only origin/master`.split("\n")
  add_group 'Changed' do |source_file|
    changed_files.detect do |filename|
      source_file.filename.ends_with?(filename)
    end
  end

  add_filter '/spec/'
  add_filter '/config/'
  add_filter 'lib/helper.rb'
end

# Ensure AWS API is never called. Fixture home folder does not contain ~/.aws/credentials
ENV['HOME'] = 'spec/fixtures/home'

require 'byebug'
require 'fileutils'
require 'jets'

abort('The Jets environment is running in production mode!') if Jets.env == 'production'
Jets.boot

require 'jets/spec_helpers'

require 'vcr'
require 'webmock/rspec'
WebMock.disable_net_connect!(allow_localhost: true)

module Helpers
  def payload(name)
    JSON.parse(File.read("spec/fixtures/payloads/#{name}.json"))
  end
end

VCR.configure do |config|
  config.allow_http_connections_when_no_cassette = false
  config.default_cassette_options = { record: :none, erb: true, match_requests_on: [:uri] }
  config.cassette_library_dir = 'spec/fixtures/vcr_cassettes'
  # config.debug_logger = $stderr
  config.hook_into :webmock
  config.ignore_localhost = true
  config.configure_rspec_metadata!
end

RSpec::Matchers.define_negated_matcher :not_change, :change

RSpec.configure do |config|
  config.example_status_persistence_file_path = 'spec/failures.txt'
  
  config.include Helpers

  config.include FactoryBot::Syntax::Methods

  config.before do
    FactoryBot.find_definitions if FactoryBot.factories.count == 0
  end

  config.before(:suite) do
    DatabaseCleaner.clean_with(:truncation)
    FactoryBot.find_definitions
  end

  config.before(:each) do
    DatabaseCleaner.strategy = :transaction
  end

  config.before(:each) do
    DatabaseCleaner.start
  end

  config.after(:each) do
    DatabaseCleaner.clean
  end

  config.before :all, rotate_seeding: true do
    Faker::Config.random = Random.new(rand(3))
  end

  config.after :all, perform_enqueued: true do
    Faker::Config.random = nil
  end
end

By the way, I noticed that if I remove the line require ‘jets/spec_helpers’ , the specs run successfully, except for the Controller Specs.

The solution was to migrate to Jets 4.0.10 and ignore Jets 5.

Same here. Jets 5 worked great for a new app but I’ve had too many issues for an older app and downgraded to 4.0.10

In my case, it’s resolved by setting config.cache_classes = true in test.rb.

There is a related issue.
