Question

这是我的模特 -

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

当我尝试运行验证时，即使我将选择更改为“1”，它也只会检查第一个“0”。任何帮助，将不胜感激！感谢

在if条件下更改为==。

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