I'm trying to get some RSpec examples working with Capybara using the javascript driver (w/ Webkit or Poltergeist) but there's a locking issue with the database when updating a table. Here's part of the example in question:

  scenario 'by changing the contract attributes', js: true do
    login_as @admin, scope: :user

    contract = Contract.create(number: '123',
                               start_at: Date.today,
                               end_at: Date.today + 1.month)

    visit "/contracts/#{contract.id}/edit"

I'm using Devise and the Warden::Test::Helpers to login.

Running RSpec takes a while and all I get:

 Failure/Error: visit "/contracts/#{contract.id}/edit"
 Capybara::Driver::Webkit::WebkitInvalidResponseError:
   Unable to load URL: http://127.0.0.1:46520/contracts/1/edit

The log is showing that there's a database locking issue:

Started GET "/contracts/1/edit" for 127.0.0.1 at 2012-06-01 12:10:26 -0400
   (0.2ms)  BEGIN
   (51083.3ms)  UPDATE `users` SET `last_sign_in_at` = '2012-06-01 16:10:26', `current_sign_in_at` = '2012-06-01 16:10:26', `last_sign_in_ip` = '127.0.0.1', `current_sign_in_ip` = '127.0.0.1', `sign_in_count` = 1, `updated_at` = '2012-06-01 16:10:26' WHERE `users`.`id` = 1
Mysql2::Error: Lock wait timeout exceeded; try restarting transaction: UPDATE `users` SET `last_sign_in_at` = '2012-06-01 16:10:26', `current_sign_in_at` = '2012-06-01 16:10:26', `last_sign_in_ip` = '127.0.0.1', `current_sign_in_ip` = '127.0.0.1', `sign_in_count` = 1, `updated_at` = '2012-06-01 16:10:26' WHERE `users`.`id` = 1
   (0.8ms)  ROLLBACK

I've tried lots of things (that question seemed to closest to an actual solution: Capybara with :js => true causes test to fail) but nothing worked, even getting rid of DatabaseCleaner. Is there anything else I could try?

Edit: Here's the spec_helper.rb file as requested:

It's almost certainly

config.use_transactional_fixtures = true

Which is trying to run your example inside of a transaction, for the purpose of having clean data. Since you're using Database Cleaner, you already have this feature, so set this to false and you should be good to go.

For me the solution was just the opposite :)

I have set it to false:

config.use_transactional_fixtures = false

And it all worked. With true it wasn't working just as before.
