FactoryGirl记录未保存

Question

I'm trying to write tests, on which company objects are saved. But, company objects are not saved, and there is no company record on the table. Why and how can I fix the problem?

db/schema.rb

ActiveRecord::Schema.define(version: 20140626075006) do
  create_table "companies", force: true do |t|
    t.string   "name"
    t.datetime "created_at"
    t.datetime "updated_at"
  end
end

app/models/company.rb

class Company < ActiveRecord::Base
end

spec/factories/companies.rb

FactoryGirl.define do
  factory :company do
    name "MyString"
  end
end

spec/models/company_spec.rb

require 'spec_helper'

describe Company do
  let(:company) { FactoryGirl.create(:company) }
  context "test context"do
    it "test" do
      Company.first.name
    end
  end
end

spec/spec_helper.rb

ENV["RAILS_ENV"] ||= 'test'
require File.expand_path("../../config/environment", __FILE__)
require 'rspec/rails'
require 'rspec/autorun'
Dir[Rails.root.join("spec/support/**/*.rb")].each { |f| require f }
RSpec.configure do |config|
  config.fixture_path = "#{::Rails.root}/spec/fixtures"
  config.use_transactional_fixtures = true
  config.infer_base_class_for_anonymous_controllers = false
  config.order = "random"
end

result

Ah, got burnt by this a couple of times.

let expressions are lazily evaluated. You didn't reference that one, so the company never got created. You can use let! , for example.

  let!(:company) { FactoryGirl.create(:company) }

Or reference that company

let(:company) { FactoryGirl.create(:company) }
context "test context"do
  it "test" do
    expect(company).to_not be_nil
    expect(Company.count).to eq 1
  end
end
