Activerecord brainspec/enumerize为默认值抛出mysql错误

我正在开发Rails 4应用程序，并开始使用brainspec/enumerize gem。我在数据库的

列status

中有一个整数值，我想在我的模型中枚举它

下面您可以看到我用来设置它的代码段。不幸的是，在我的测试（之前都通过了）中，它抱怨由于无法保存行而创建了

合作伙伴。无法将默认状态分配为
NULL
。不确定从何处获取
NULL
，因为数据库本身（MySQL）设置为默认值
0
，从下面可以看到，后端指示默认值
4
或
：complete

enumerize :status, in: [
    :pending,    # 0 account has a pending billing request (but is not yet open)
    :active,     # 1 account has an active base subscription
    :suspended,  # 2 account has been suspended (e.g. after a base subscription decline)
    :expired,    # 3 base subscription has expired
    :incomplete, # 4 partner application process incomplete
    :closed,     # 5 account has been permanently closed
    :cancelled   # 6 account has been cancelled by user (but is still unexpired)
], default: :incomplete

下面是ActiveRecord/MySQL错误

PartnerTest#test_create_with_nested_attributes:
ActiveRecord::StatementInvalid: Mysql2::Error: Column 'status' cannot be null: UPDATE `partner` SET `primary_contact_id` = 3, `status` = NULL WHERE `partner`.`id` = 3
    test/models/partner_test.rb:9:in `block in <class:PartnerTest>'

根据brainspec/enumerize自述文件，您应该为每个状态提供一个整数值，如：

enumerize :status, in: {
  pending: 0,    # 0 account has a pending billing request (but is not yet open)
  active: 1,     # 1 account has an active base subscription
  suspended: 2,  # 2 account has been suspended (e.g. after a base subscription decline)
  expired: 3,    # 3 base subscription has expired
  incomplete: 4  # 4 partner application process incomplete
                 # And so on...
}, default: :incomplete

因为您只提供了键而没有提供值，所以它将其设置为nil/NULL

enumerize :status, in: {
  pending: 0,    # 0 account has a pending billing request (but is not yet open)
  active: 1,     # 1 account has an active base subscription
  suspended: 2,  # 2 account has been suspended (e.g. after a base subscription decline)
  expired: 3,    # 3 base subscription has expired
  incomplete: 4  # 4 partner application process incomplete
                 # And so on...
}, default: :incomplete
