活动管理员输入两个日期验证

Question

When I'm creating new object model in ActiveAdmin for bonus table I would like to be able to validate if start_date is lower than end_date. I tried using

def create
  if params[:current_period_start] > params[:current_period_end]
    return redirect...
  end
  super 
end

but it fails because my request data looks like this:

"bonus"=>{"current_period_start(1i)"=>"2018", "current_period_start(2i)"=>"3",
"current_period_start(3i)"=>"2", "current_period_start(4i)"=>"02", 
"current_period_start(5i)"=>"03", "current_period_end(1i)"=>"2022", 
"current_period_end(2i)"=>"3", "current_period_end(3i)"=>"5", 
"current_period_end(4i)"=>"04", "current_period_end(5i)"=>"05"}, "id"=>"14"}

Can someone suggest me how to transform this into whole date? Or another simpler solution

Do you need to redefine the create method in the ActiveAdmin controller? I would remove the whole create method and add a custom validation in the Bonus model (which I assume is located at app/models/bonus.rb )

class Bonus < ApplicationRecord
  validates :current_period_start_should_be_before_current_period_end
  def current_period_start_should_be_before_current_period_end
    if current_period_end < current_period_start
      errors.add(:current_period_start, "Should be before current period end")
    end
  end
end
