Factory_bot_rails 创建带有特征的哈希值。

Question

我想用以下方法创建哈希值 factory_bot_rails

let(:expected_hash) do
  {
    'fields' => {
      'summary' => 'member added as a collaborator to repository',
      'description' => "[OutsideCollaboratorAdded]\n-----------------\nMember: member,\n Added to project: repository,\n by: sender",
      'project' => { 'id' => '22501' },
      'issuetype' => { 'id' => '11800' },
      'customfield_14400' => '2020-04-23'
    }
  }
end

这个想法就是要有这些领域。summary, description, project 和 issue_type 可通过使用 trait. 所以，我试图类似的东西。

  factory :expected_ticket_fields do
    fields {{
      summary => 'test',
      description => 'test desc',
      customfield_14400 => '2020-04-23'
      }}

    trait :member_added do
      summary { 'member added as a collaborator to repository' }
      description { '[OutsideCollaboratorAdded]\n-----------------\nMember: member,\n Added to project: repository,\n by: sender' }
      project {{ 'id' => '22501' }}
    end
  end

和规格，

  before do
    hash = create(:expected_ticket_fields)
    hash.member_added
  end

但我得到一个错误: uninitialized constant ExpectedTicketFields

FactoryBot的工作原理和你使用的不一样。

1）FactoryBot是 不 一个Hash，它是FactoryBot对象的一种类型.2)一个同名的ActiveRecord需要存在(比如 "Ticket "或 "Project")，FactoryBot才能工作。

你要创建一个特质，那么如果你想要那种Ticket，你就会这样写。

factory :ticket do
  # you can specify the default `summary`
  summary { 'This is a ticket' }
  trait :ticket_with_member_added do
    summary { 'This is a ticket with a member added' }
    description { '[OutsideCollaboratorAdded]\n-----------------\nMember: member,\n Added to project: repository,\n by: sender' }
    # If you are planning on using a Project ActiveRecord, then you must ALSO create a factory for project, then this will trigger a Project to be created.
    project
  end
end

# In your tests
ticket = create(:ticket_with_member_added)
