Models created with FactoryGirl aren't available in controller - ruby-on-rails

Question

Original question
I'm trying to write some feature tests with RSpec and Capybara and wonder, why my gon object is always empty allthough it was set in my controller:
app/controllers/timetrackings_controller.rb:
class TimetrackingsController < ApplicationController
include ApplicationHelper
before_action :authenticate_user!
before_action :set_timetracking, only: [:update, :destroy]
# GET /timetrackings
def index
projects = Project.all_cached.select('id, name, category, number, customer_id').includes(:customer).where(:archived => false).order(:number)
gon.projects = group_by_customer(projects).to_h
gon.services = Service.all_cached.select('id, name').where(:archived => false).order('LOWER(name)')
end
...
Now I've wondered why this data doesn't get rendered into my view (debugged with save_and_open_page: //<![CDATA[ window.gon={};gon.projects={};gon.services=[]; //]]>), so I just tried to get the gon values in my test file:
require 'spec_helper'
describe 'the timetracking page', :js => true do
before :each do
switch_to_subdomain('test')
#project = FactoryGirl.create(:project)
#service = FactoryGirl.create(:service)
user = FactoryGirl.create(:user)
login_as(user, :scope => :user)
visit '/timetracking'
save_and_open_page
end
it 'renders the react component' do
expect(page).to have_selector '#timetracking-form'
end
it 'allows me to create a new timetracking' do
within('#timetracking-form') do
fill_in 'duration', :with => '2'
puts '########'
puts Gon.all_variables
puts Project.all.to_json
puts Service.all.to_json
puts '########'
find_field('project_id').find("option[value='#{#project.id}']").click
end
click_button '.ei-icon-check'
end
end
But the output is just:
########
{}
[{"id":2,"number":"2","name":"project2","description":"Some notes","archived":false,"customer_id":2,"created_at":"2015-11-30T16:05:40.160+01:00","updated_at":"2015-11-30T16:05:40.160+01:00","rate_type":null,"hourly_rate":null,"service_rates":null,"budget_type":null,"budget_rate":null,"category":"A","deadline":null}]
[{"id":2,"name":"service2","description":"Some notes","archived":false,"created_at":"2015-11-30T16:05:40.173+01:00","updated_at":"2015-11-30T16:05:40.173+01:00","billable":null,"hourly_rate":null}]

Thats my spec_helper.rb:
require 'devise'
# Setup Capybara
require 'capybara/rspec'
require 'capybara/poltergeist'
Capybara.always_include_port = true
Capybara.javascript_driver = :poltergeist
# Use SimpleCov for code coverage
require 'simplecov'
require 'simplecov-shield'
SimpleCov.start 'rails'
SimpleCov.formatters = [
SimpleCov::Formatter::HTMLFormatter,
SimpleCov::Formatter::ShieldFormatter
]
# This file is copied to spec/ when you run 'rails generate rspec:install'

require 'rspec/rails'

# Requires supporting ruby files with custom matchers and macros, etc, in

# run twice. It is recommended that you do not name files matching this glob to
# end with _spec.rb. You can configure this pattern with with the --pattern

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

ActiveRecord::Migration.check_pending! if defined?(ActiveRecord::Migration)
module ControllerMacros
def attributes_with_foreign_keys(*args)
FactoryGirl.build(*args).attributes.delete_if do |k, v|
['id', 'type', 'foreign_id', 'foreign_type', 'created_at', 'updated_at'].member?(k)
end
end
end
RSpec.configure do |config|
config.use_transactional_fixtures = false
config.use_instantiated_fixtures = false
config.mock_with :rspec
# Use FactoryGirl for fixtures
config.include FactoryGirl::Syntax::Methods
# Auto-detect spec types
config.infer_spec_type_from_file_location!
# Insert devise helpers in controller specs
config.include Devise::TestHelpers, type: :controller

config.before(:suite) do
Warden.test_mode!

DatabaseCleaner.strategy = :transaction

Account.create!(name: 'Test', domain: 'test', email: 'info#example.com')
end
config.before(:each) do
# Start transaction for this test
DatabaseCleaner.start
# Switch into the default tenant
Apartment::Tenant.switch! 'test'
# Use Timecop to freeze times on time-critical tests
Timecop.return
end
config.after(:each) do
# Reset tentant back to `public`
Apartment::Tenant.reset
# Rollback transaction
DatabaseCleaner.clean
end
end
Update
OK, I think the problem lies elsewhere:
After creating models with FactoryGirl (like FactoryGirl.create(:project)), the records aren't available in the controller. If I write something like
#foo = Project.all.to_json
in my controller and want to display this data in my view, I just get [] (after calling save_and_open_page).
I though FactoryGirl.create writes data directly to the DB? Why isn't the data available in my controller methods?
Update 2
Adding
config.before(:each, :js => true) do
DatabaseCleaner.strategy = :truncation
end
solves this problem, but now I get:
Failure/Error: user = FactoryGirl.create(:user)
ActiveRecord::RecordNotUnique:
PG::UniqueViolation: ERROR: duplicate key value violates unique constraint "index_users_on_lastname"
DETAIL: Key (lastname)=(Kautzer) already exists.
: INSERT INTO "users" ("email", "initial", "firstname", "lastname", "encrypted_password", "archived", "created_at", "updated_at") VALUES ($1, $2, $3, $4, $5, $6, $7, $8) RETURNING "id"
I thought the database gets cleaned after each test?
Update 3
Disregard, the last problem was a mistake in my database setup.

Answer 1

Adding
config.before(:each, :js => true) do
DatabaseCleaner.strategy = :truncation
end
to my spec_helper.rb solves the problem :)
