Factory Girl creates objects, but objects not found in the database

I use a cucumber with Factory Girl and here is a mysterious problem,

at my stages of cucumber:

fact = Factory.create(:fact,
                   :factable_type => "type_#{i}",
                   :factable_id => i.to_s,
                   :factable_action => "action_#{i}",
                   :priority => "1"
    )

When I check the debug mode with ruby ​​mine, I have a fact with an identifier, but if I register my IRB test console:

ruby-1.9.2-p180 :011 > Fact.all
 => [] 

Of course, when I want to run my tests and check for objects in the database, my tests fail because of this. Do you have any ideas?

Here is my env.rb file:

# IMPORTANT: This file is generated by cucumber-rails - edit at your own peril.
# It is recommended to regenerate this file in the future when you upgrade to a 
# newer version of cucumber-rails. Consider adding your own code to a new file

# files.

require 'cucumber/rails'
require 'fakeweb'
require "factory_girl"

# Add this to load Capybara integration:
require 'capybara/rspec'
require 'capybara/rails'

require File.expand_path('../../../spec/vcr_setup.rb', __FILE__)

# Capybara defaults to XPath selectors rather than Webrat default of CSS3. In
# order to ease the transition to Capybara we set the default here. If you'd
# prefer to use XPath just remove this line and adjust any selectors in your
# steps to use the XPath syntax.
Capybara.default_selector = :css

Capybara.run_server = true #Whether start server when testing
Capybara.default_selector = :xpath #default selector , you can change to :css
Capybara.default_wait_time = 2 #When we testing AJAX, we can set a default wait time
Capybara.ignore_hidden_elements = false #Ignore hidden elements when testing, make helpful when you hide or show elements using javascript

# By default, any exception happening in your Rails application will bubble up
# to Cucumber so that your scenario will fail. This is a different from how 
# your application behaves in the production environment, where an error page will 
# be rendered instead.
#
# Sometimes we want to override this default behaviour and allow Rails to rescue
# exceptions and display an error page (just like when the app is running in production).
# Typical scenarios where you want to do this is when you test your error pages.
# There are two ways to allow Rails to rescue exceptions:
#
# 1) Tag your scenario (or feature) with @allow-rescue
#
# 2) Set the value below to true. Beware that doing this globally is not
# recommended as it will mask a lot of errors for you!
#
ActionController::Base.allow_rescue = false

# Remove/comment out the lines below if your app doesn't have a database.
# For some databases (like MongoDB and CouchDB) you may need to use :truncation instead.
#begin
#  DatabaseCleaner.strategy = :transaction
#rescue NameError
#  raise "You need to add database_cleaner to your Gemfile (in the :test group) if you wish to use it."
#end

# You may also want to configure DatabaseCleaner to use different strategies for certain features and scenarios.
# See the DatabaseCleaner documentation for details. Example:
#
#   Before('@no-txn,@selenium,@culerity,@celerity,@javascript') do
#     DatabaseCleaner.strategy = :truncation, {:except => %w[widgets]}
#   end
#
#   Before('~@no-txn', '~@selenium', '~@culerity', '~@celerity', '~@javascript') do
#     DatabaseCleaner.strategy = :transaction
#   end
#

## Sets up the Rails environment for Cucumber
ENV["RAILS_ENV"] = "test"
require File.expand_path(File.dirname(__FILE__) + '/../../config/environment')
require 'cucumber/rails/world'
Cucumber::Rails::World.use_transactional_fixtures

##Seed the DB

Before do
    Capybara.default_host = 'http://site.local'

and in factories.rb:

Factory.define :fact do |i|
  i.factable_type "Follow"
  i.factable_id   "1"
  i.factable_action     "create"
  i.is_processed  "false"
