运行我的 rake 任务时收到以下错误：
Validation failed: Account can't be blank
这是引发错误的代码位：
test.entries.create!({
:account_id => account.id,
:date => date
})
我对两者的验证test仅entries验证:account_id. 我知道错误信息是人性化的删除.id，但很明显:account_id存在。我在这里想念什么？我正在使用导轨 3.1.14。
编辑：
完整的跟踪错误如下 -
rake aborted!
Validation failed: Account can't be blank
