我有一个错误的问题：
ActiveRecord::RecordInvalid
由此引起的：
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,因为类似的让我们在另一个测试中工作.我尝试使用tap方法调试但它没有显示错误消息(在另一种情况下很好的礼物).
如果我应该添加一些额外的数据(我的模型看起来如何等),请写信.
我看到如果我评论第一个让或第二个,测试通过.它看起来像两个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？
更新：
完整的错误消息：
Failure/Error: let(:ind2){ build(:ind2).tap {|e| p e.valid?; p e.errors} }

更新2：
当我在工厂中设置date_of_training Date.today时,错误消失.我也尝试手动设置日期,如2016-08-23,但它仍然是InvalidRecord.也是Date.today 1.day不工作.知道什么可能是错的吗？也许date_of_training不是直接问题.
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？

belongs_to :trainer, class_name: 'Person', foreign_key: 'trainer_id'
belongs_to :client, class_name: 'Person', foreign_key: 'client_id'

hiredate { Faker::Time.between('2016-01-01', '2016-04-30') }
end
end
更新6：
在另一个背景下,我有这个让：
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
最佳答案 这可能是“无效记录错误”背后的原因 –
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,并请检查与其相关的验证.您的验证有问题.
