Database cleaner with multiple DBs

Inizia con la configurazione di DatabaseCleaner[:sequel] nello spec helper fornito e con la connessione del modello Sequel per CameraActivity, quindi riproduci il problema facendo puntare entrambi gli URL del database allo stesso database. Esamina la suite di test esistente per determinare come vengono rilevati e configurati più database Sequel attivi; il lavoro è completato quando la configurazione dei test pulisce le connessioni ai database previsti senza l’errore di runtime.

I have been using DB cleaner with my only db but now I have 2 of them, and I am getting this error in testing mode as

RuntimeError:
  As you have more than one active sequel database you have to specify the one to use manually!

At first my whole sequel models were using only one db but now i have connected my one model with a separate Db as

class CameraActivity < Sequel::Model(Sequel.connect(ENV['SNAPSHOT_DATABASE_URL'])[:camera_activities])

and in spec helper I have these configurations

# This file is copied to spec/ when you run 'rails generate rspec:install'
ENV["RAILS_ENV"] = 'test'
ENV["DATABASE_URL"] = "postgres://localhost/evercam_tst"
ENV["RACK_ENV"]  = ENV["RAILS_ENV"]
require File.expand_path("../../config/environment", __FILE__)
require 'rspec/rails'
require 'webmock/rspec'
require 'factory_girl'
require 'rack_session_access/capybara'
require "simplecov"
SimpleCov.start

Dir[Rails.root.join("spec/support/**/*.rb")].each { |f| require f }

require 'database_cleaner'
require 'capybara/poltergeist'
require 'simplecov'

SimpleCov.start 'rails'

#Capybara.server_port = 3001
#Capybara.app_host = "http://local.evercam.io:3001"
Capybara.javascript_driver = :poltergeist

RSpec.configure do |config|
  config.infer_spec_type_from_file_location!

  config.filter_run :focus => true
  config.run_all_when_everything_filtered = true

  # Configure factory girl stuff.
  config.include FactoryGirl::Syntax::Methods

  # Configure database cleaner.
  config.before(:suite) do
    WebMock.allow_net_connect!
    DatabaseCleaner[:sequel].strategy = :truncation, {except: %w[spatial_ref_sys]}
    DatabaseCleaner[:sequel].clean_with(:truncation, except: %w[spatial_ref_sys])
  end

  config.before(:each) do
    DatabaseCleaner[:sequel].start
  end

  config.after(:each) do
    DatabaseCleaner[:sequel].clean
  end
end

# Load up factories.
FactoryGirl.find_definitions
```


my other DB is `ENV['SNAPSHOT_DATABASE_URL']` But for testing purposes both DB URLs are directed to one database. How is that possible to tell DB Cleaner to handle that case?
