这是我当前的类定义和规范:
class Event < ActiveRecord::Base
# ...
state_machine :initial => :not_started do
event :game_started do
transition :not_started => :in_progress
end
event :game_ended do
transition :in_progress => :final
end
event :game_postponed do
transition [:not_started, :in_progress] => :postponed
end
state :not_started, :in_progress, :postponed do
validate :end_time_before_final
end
end
def end_time_before_final
return if end_time.blank?
errors.add :end_time, "must be nil until event is final" if end_time.present?
end
end
describe Event do
context 'not started, in progress or postponed' do
describe '.end_time_before_final' do
['not_started', 'in_progress', 'postponed'].each do |state|
it 'should not allow end_time to be present' do
event = Event.new(state: state, end_time: Time.now.utc)
event.valid?
event.errors[:end_time].size.should == 1
event.errors[:end_time].should == ['must be nil until event is final']
end
end
end
end
end
当我运行规范时,我得到了两次失败和一次成功。我不知道为什么。对于其中两种状态,方法中的return if end_time.blank?
语句在end_time_before_final
每次都应该为假时评估为真。“推迟”是唯一似乎通过的状态。关于这里可能发生什么的任何想法?
