使用FactoryGirl创建的模型在控制器中不可用
原始问题
我正在尝试用RSpec和Capybara编写一些function测试，并想知道为什么我的gon对象总是空的，尽管它是在我的控制器中设置的：
app/controllers/timetrackings_controller.rb ：
class TimetrackingsController 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 ...
现在我想知道为什么这些数据没有呈现到我的视图中（使用save_and_open_page ： // ），所以我只是试图在我的测试文件中获取gon值：
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
但输出只是：
######## {} [{"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}] ########
那是我的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' ENV['RAILS_ENV'] ||= 'test' require File.expand_path('../../config/environment', __FILE__) require 'rspec/rails' require 'shoulda-matchers' # Requires supporting ruby files with custom matchers and macros, etc, in # spec/support/ and its subdirectories.

'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
更新
好吧，我认为问题出在其他地方：
使用FactoryGirl创建模型（如FactoryGirl.create(:project) ）后，控制器中的记录不可用。 如果我写的东西像
@foo = Project.all.to_json
在我的控制器中，想要在我的视图中显示这些数据，我只是得到[] （在调用save_and_open_page ）。
我虽然FactoryGirl.create直接将数据写入数据库？ 为什么我的控制器方法中的数据不可用？
更新2
添加
config.before(:each, :js => true) do DatabaseCleaner.strategy = :truncation end
解决了这个问题，但现在我得到了：
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"
我认为每次测试后数据库都会被清理干净？
更新3
无视，最后一个问题是我的数据库设置错误。
添加
config.before(:each, :js => true) do DatabaseCleaner.strategy = :truncation end
到我的spec_helper.rb解决了问题:)
