Question

我正在开发一个Rails 4应用程序，我已经开始使用brainspec / enumerize gem了。我在数据库中有一个整数值，列status，并希望在我的模型中枚举它。

下面你可以看到我用来设置它的代码片段。不幸的是，在我的测试中（之前都已通过），由于无法保存行，因此抱怨创建Partner。无法指定默认状态NULL。不知道它来自NULL的位置，因为数据库本身（MySQL）设置为默认值0，从下面可以看出，后端端指示默认值为{ {1}}或4。

:incomplete

这是ActiveRecord / MySQL错误。

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

此外，我知道Enumerize正在接收默认值（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>'）。如果我把乱码扔进默认值（:incomplete），它就会被打包。

我正在使用master / branch，因此它适用于Rails 4。

的Gemfile

default: :asdoiasoas

根据brainspec / enumerize README，您应该为每个状态提供一个整数值，例如：

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

由于您只提供了键而不是值，因此将其设置为nil / NULL。

brainspec / enumerize抛出mysql错误的默认值
