Railsの4 - カスタム検証エラー

Question

これは私のモデルである -

class Leave < ActiveRecord::Base 
belongs_to :staff 
validates :staff, :leave_type, :start_date, :end_date, :number_of_days, :approved_by, presence: true 
enum leave_type: {Medical: 0, Annual: 1, Urgent: 3, "Birth Leave": 4} 
validate :check_leave, :if => "self.number_of_days.present?" 




protected 

def check_leave 
    if self.leave_type = 0 
    if (self.number_of_days + LeaveAllocation.last.medical_leave_counter) > LeaveAllocation.last.medical_leave 
     self.errors.add(:number_of_days, "Days exceeded the limit") 
    end 
    end 
    if self.leave_type = 1 
    if (self.number_of_days + LeaveAllocation.last.annual_leave_counter) > LeaveAllocation.last.annual_leave 
     self.errors.add(:number_of_days, "Days exceeded the limit") 
    end 
    end 

end 

end 

私は検証を実行しようとすると、それだけで私は選択を「1」に変更しても小切手に「0」最初のものと思われます。どんな助けもありがとう！ありがとう

Answer 1

if条件で==に変更してください。

self.leave_type == 0 and 
self.leave_type == 1
