我遇到错误问题：
ActiveRecord::RecordInvalid
由此引起：
let(:ind2){ build(:ind2) }
Rspec测试：
describe '#client_free_time_validation' do
let(:ind) { build(:ind).tap {|e| p e.valid?; p e.errors}}
let(:ind2){ build(:ind2).tap {|e| p e.valid?; p e.errors} }
context 'when training is during another training' do
it 'raises an error' do
expect(ind.valid?).to be_truthy
expect(ind2.valid?).to be_falsey
# expect(ind2.errors.count).to eq 1
# expect(ind2.errors[:base]).to eq(['Masz w tym czasie inny trening.'])
end
end
厂：
FactoryGirl.define do
factory :individual_training do
date_of_training { Date.today.next_week.advance(days: 1) }
association :client, factory: :client
association :trainer, factory: :trainer
start_on Time.parse('12:30')
end_on Time.parse('13:30')
association :training_cost, factory: :tc2
factory :ind do
start_on Time.parse('11:00')
end_on Time.parse('12:00')
end
factory :ind2 do
start_on Time.parse('10:30')
end_on Time.parse('11:30')
end
end
end
我很困惑，因为类似的let在另一个测试中工作。我尝试使用tap方法进行调试，但它没有显示错误消息（在另一种情况下是很好的礼物）。
如果我应该提供一些额外的数据（我的模型看起来如何等），请写一下。
我看到如果我评论第一个let或第二个，那么测试就会通过。它会查看两个let（ind和ind2）无法一起工作的情况。
通过test生成的属性的示例值：
#<ActiveModel::Errors:0x00000001f4ade8 @base=#<IndividualTraining id: nil, date_of_training: "2016-08-23", client_id: 28, trainer_id: 29, start_on: "2016-08-20 11:00:00", end_on: "2016-08-20 12:00:00", training_cost_id: 4>, @messages={}>
您是否有建议如何调试哪些记录无效？

完整的错误消息：

更新2：
我在工厂设置date_of_training Date.today时错误消失了。我也尝试手动设置日期，如2016-08-23，但它仍然是InvalidRecord。 Date.today + 1.day也无法正常工作。知道什么可能是错的吗？也许date_of_training不是一个直接的问题。
更新3： IndividualTraining模型验证：
private
def date_and_start_on_validation
unless start_on.blank?
if date_of_training < Date.today
errors.add(:base, 'You cannot set individual training before today.')
elsif date_of_training == Date.today
if start_on <= Time.now
errors.add(:base, 'Time of today training is before current time.')
end
end
end
end
# check if trainer work while will be individual_training
def date_of_training_validation
unless start_on.blank?
trainer.work_schedules.each_with_index do |ti, ind|
if ti.day_of_week == BackendController.helpers.translate_date(date_of_training)
if (start_on.strftime('%H:%M')..end_on.strftime('%H:%M'))
.overlaps?(ti.start_time.strftime('%H:%M')..ti.end_time.strftime('%H:%M'))
break
else
errors.add(:base, 'Training is outside of trainer work schedule.')
end
elsif ind == trainer.work_schedules.size - 1
errors.add(:base, 'In this day trainer doesn't work.')
end
end
end
end
# check if client doesn't have another training or activity
def client_free_time_validation
unless start_on.blank?
client.individual_trainings_as_client.where(date_of_training: date_of_training)
.where('id != ?', id).each do |ci|
if (start_on...end_on).overlaps?(ci.start_on...ci.end_on)
errors.add(:base, 'You have another training.')
end
end
client.activities.where(day_of_week: BackendController.helpers.translate_date(date_of_training))
.each do |ca|
if (start_on...end_on).overlaps?(ca.start_on...end_on)
errors.add(:base, 'You have another activity.')
end
end
end
end
更新4： 我注意到如果我第一次执行ind.valid？ - 它将是真的，ind2将是RecordInvalid。但是当我重新加载并检查ind2.valid？ - 现在这是真的而且是假的。
更新5： 我使用相同的let但在不同的上下文中分别使用，并且传递了rspec。可能是什么原因，我不能在相同的上下文中使用两个let？
个人培训协会
belongs_to :trainer, class_name: 'Person', foreign_key: 'trainer_id'
belongs_to :client, class_name: 'Person', foreign_key: 'client_id'
belongs_to :training_cost

FactoryGirl.define do
factory :person do

end
factory :client, parent: :person, class: 'Client' do

type 'Trainer'
salary { Faker::Number.decimal(4, 2) }
hiredate { Faker::Time.between('2016-01-01', '2016-04-30') }
end
end
更新6： 在另一个背景下，我有这个：
let(:individual_training) { build :individual_training, trainer_id: work_schedule[:person_id] }
let(:ind2) do
build :individual_training,
trainer_id: work_schedule[:person_id],
date_of_training: Date.today.next_week.advance(days: 0),
start_on: Time.now - 1.hour,
end_on: Time.now
end
这很好用。没有错误：RecordInvalid
答案 0 :(得分：2)
这可能是背后的原因＆＃34;无效的记录错误＆＃34; -
Reason - It usually happens when you use "create" and "build" together.
create method persists the instance while the build method keeps it only in memory.
首先，我建议您使用构建方法，并请检查与之相关的验证。您的验证有问题。
