Factory_Girl Rspec 的“未初始化常量用户”答案

【问题标题】："Uninitialized constant User" for Factory_Girl RspecFactory_Girl Rspec 的“未初始化常量用户”
【发布时间】：2015-04-23 13:04:33
【问题描述】：

我正在尝试为我的用户模型设置我的 Factory Girl 工厂，但如果没有出现某种错误，我似乎无法获得它。我现在得到的错误是“未初始化的常量用户”

spec/factories.rb

factory :user do |user|

user.name "John Doe"
user.admin false
user.created_at Time.now
user.updated_at Time.now
user.password_digest nil
user.remember_token nil
user.e_admin nil
user.t_admin true
user.d_admin false
user.activated false
user.activated_at Time.now
end

spec/spec_helper.rb

require 'rails/all'
require 'rspec/rails'
require 'factory_girl_rails'

RSpec.configure do |config|

  config.expect_with :rspec do |expectations|
    expectations.include_chain_clauses_in_custom_matcher_descriptions = true
  end

  config.mock_with :rspec do |mocks|
    mocks.verify_partial_doubles = true
  end

  config.filter_run :focus
  config.run_all_when_everything_filtered = true

  config.disable_monkey_patching!
  config.warnings = true
  if config.files_to_run.one?
    config.default_formatter = 'doc'
  end

  config.profile_examples = 10

  config.order = :random
  Kernel.srand config.seed

  config.include FactoryGirl::Syntax::Methods

  FactoryGirl.definition_file_paths = [File.expand_path('../factories', __FILE__)]
  FactoryGirl.find_definitions

end

spec/user_spec.rb

require 'rspec'
require 'spec_helper'
require 'factory_girl_rails'


RSpec.describe 'Log In' do

  it 'should log user in' do

    var = create(:user)

    expect(var.valid?).to eql(true)
  end
 end

有谁知道我该如何解决这个错误？

  1) Log In should log user in
     Failure/Error: var = FactoryGirl.create(:user)
     NameError:
       uninitialized constant User

【问题讨论】：

您在 app/models 目录中确实有一个 User 类，对吧？
我认为这行不通，但试试 var = FactoryGirl.create(:user)
添加 RSpec 后是否运行rails generate rspec:install？
我不这么认为，我没有“rails_helper.rb”。我刚刚运行它，但我得到了同样的错误。我必须向 rails_helper.rb 添加任何内容吗？

【解决方案1】：

我想通了，我必须将 --require rails_helper 添加到我的 .rspec 文件中。然后我不得不取出我的“FactoryGirl.find_definitions”行，因为我收到一个错误，我有多个用户工厂。感谢大家的帮助！

【解决方案2】：

你的工厂应该是这样的

FactoryGirl.define do
  factory :user do
    name "John Doe"
    admin false
    created_at Time.now
    updated_at Time.now
    password_digest nil
    remember_token nil
    e_admin nil
    t_admin true
    d_admin false
    activated false
    activated_at Time.now
  end
end

在文件夹结构中 - spec/factories/user.rb

【讨论】：

您的模型中是否确实有一个 user.rb 文件并运行 rake db:migrate 来创建用户？不得不问:)
是的，我愿意。我再次运行迁移，但仍然没有运气。
可能包括相关错误的堆栈跟踪。可能会更深入地了解错误。
