これ以上の期限なしここで私がDriverLicenseモデルに大量に割り当てようとしている私のパラメータ
{"utf8"=>"✓",
"authenticity_token"=>"cKhruPzVvBK63bqCQPFY8xPZb12V5lhLPOpXgjIToJk=",
"driver_license"=>
{"license_number"=>"LICENCE-001",
"license_class"=>"A-CLASS",
"validity_start_date"=>"02/01/2011",
"validity_end_date"=>"08/24/2011",
"issuing_authority"=>"RTO",
"remarks"=>"Remarks .."},
"save_button"=>"Save",
"action"=>"create",
"controller"=>"driver_licenses",
"driver_id"=>"2"}
ここにコントローラーコード
@driver_license = @driver.driver_licenses.new(params[:driver_license])
ここで、モデルの定義は次のようになります。
class DriverLicense < ActiveRecord::Base
acts_as_tenant(:tenant)
validates :driver_id,:license_number,:validity_start_date,:validity_end_date,:presence => true
validate :date_validity ,:if => :is_date_present?
validate :overlapping_validity,:if => :validity_start_date_present?
belongs_to :driver
scope :active_licenses , where('validity_start_date <= ? and validity_end_date >= ?',Date.today,Date.today)
.... ....
.... ....
private
def is_date_present?
validity_start_date.present? and validity_end_date.present?
end
def date_validity
errors.add(:validity_start_date,"must be earlier then validity end date") if validity_start_date > validity_end_date
end
def validity_start_date_present?
validity_start_date.present?
end
def overlapping_validity
arel = self.class.where('validity_end_date >= ?',validity_start_date).where('driver_id = ?',driver_id)
arel = arel.where('id != ?',id) if id.present?
unless arel.count.zero?
errors.add(:validity_start_date,"overLapping date with other licenses")
end
end
end
マス属性は、validity_end_dateを除くすべての属性で機能します
#<DriverLicense id: nil, driver_id: 2, license_number: "LICENCE-001", license_class: "A-CLASS", issuing_authority: "RTO", validity_start_date: "2011-01-02", validity_end_date: nil, remarks: "Remarks ..", tenant_id: 2, created_at: nil, updated_at: nil>
スクリーンショットでそれを確認できます。また、 validity_end_dateを除くすべての属性に対して一括割り当てが機能する場合も確認できます。
