before_validation on create not working

Question

在我的模特中我有

class Test < ActiveRecord::Base
  before_validation :set_pending, on: :create
  validates :status, presence: true, inclusion: { in: %w(passed failed pending) }
  .
  .
  .
  private

  def set_pending
    status = 'pending'
  end
end

在我的rails控制台中，我正在尝试创建一个新的测试

Test.create!(user_id: 9, runnable: true) 

但我收到错误

ActiveRecord::RecordInvalid: Validation failed: Status can't be blank

我做错了什么？我在ruby 2.1.8和rails 4.0.13上。感谢

我个人的偏好是在设置变量时非常明确，实际上你错过了self

def set_pending self.status = 'pending' end
