seeds.rb dosyasında geçersiz kayıt

Question

Seeds.rb dosyasında, oluşturma veri yöntemimle ilgili sorunu bulmakta sorun yaşıyorum. Veri oluşturmak için faker gem kullanıyorum. Kodum:

NAZWY_DNI = ['Poniedziałek', 'Wtorek', 'Środa', 'Czwartek', 'Piątek', 'Sobota', 'Niedziela'] 
60.times do 
    WorkSchedule.create!(
    start_time: Faker::Time.forward(1, :morning).strftime("%H:%M"), 
    end_time: Faker::Time.forward(1, :afternoon).strftime("%H:%M"), 
    day_of_week: NAZWY_DNI[Random.new.rand(0..6)], 
    person_id: Faker::Number.between(52, 112) 
) 
end 
    p "Created #{WorkSchedule.count} work schedules" 

WorkSchedule masa modeli:

# == Schema Information 
# 
# Table name: work_schedules 
# 
# id   :integer   not null, primary key 
# start_time :time    not null 
# end_time :time    not null 
# day_of_week :string   not null 
# created_at :datetime   not null 
# updated_at :datetime   not null 
# person_id :integer 
# 

Ben rake db:migrate çalıştığınızda bir hata var: ActiveRecord::RecordInvalid. Nerede hata yaptığımı biliyor musun? Şimdiden teşekkürler.

Tam iz: start_time/end_time sütun şema tipinde

Answer 1

Sorunun ne olduğunu keşfettim. Modelde work_schedule.rb Bu doğrulamayı yapmıştım: Bu satırı yorumladığımda, tohum yüklendi.

Answer 2

time olduğunu. Ancak, tohumlarınızda, zamanı dize dönüştüren strftime("%H:%M") aramasına sahipsiniz. Bu nedenle, strftime'u aramamalısınız.

Ayrıca, NAZWY_DNI[Random.new.rand(0..6)] yerine NAZWY_DNI.sample kullanarak rastgele bir gün seçeceksiniz. Faker::Number.between(52, 112) yerine sadece rand(52, 112) kullanın.
