rails tasks and generators are failing

I have a quite fresh Rails 6 installation, where I removed MySQL and replaced it with Mongoid.

When I try to run: rails g devise:install

As you can see something is using still active_record but I removed it everywhere in my code This is my stacktrace:

/Users/jan/.rbenv/versions/2.6.3/lib/ruby/gems/2.6.0/gems/railties-6.0.0/lib/rails/application/configuration.rb:240:in `database_configuration': Cannot load database configuration:

How can I overcome this issue?

(I also deleted everything in /tmp/cache)

This is the beginning of my application.rb:

require_relative 'boot'

require "rails"
# Pick the frameworks you want:
require "active_model/railtie"
require "active_job/railtie"
require "active_storage/engine"
require "action_controller/railtie"
require "action_mailer/railtie"
require "action_mailbox/engine"
require "action_text/engine"
# require "action_view/railtie"
# require "action_cable/engine"
# require "sprockets/railtie"
# require "rails/test_unit/railtie"
require "sprockets/railtie"

This is a bug in Spring/Rails 6. See https://github.com/rails/spring/issues/601.

Workarounds are:

  1. removing Spring from your application;
  2. providing a full ActiveRecord configuration, for example using sqlite.

This issue only happens in development - you don't need a production AR configuration because spring shouldn't be loaded in production.

You need to configure devise to work with mongoid instead of ActiveRecord.

Add this

require 'devise/orm/mongoid'

to devise.rb initializer.

For more info check this and this
