如何迭代 rails activeadmin CSV 中的数组？

Question

I was trying to create a custom CSV in active admin for Saloon model and I have one column with an array of OperationalHours.

Here is my Object:

[20] pry(main)> Saloon.first
=> #<Saloon:0x00007fa773496cf0
 id: 1,
 address_1: "1313 2nd St South",
 city: "Battlefield",
 state: "Missouri",
 zip: "63303",
 operational_hours:
  [#<OperationalHours:0x00007fa77aa72848 @closing_time="5:00 PM", @notes="", @opening_time="9:00 AM">,
   #<OperationalHours:0x00007fa77aa725f0 @closing_time="5:00 PM", @notes="", @opening_time="9:00 AM">,
   #<OperationalHours:0x00007fa77aa723c0 @closing_time="5:00 PM", @notes="", @opening_time="9:00 AM">,
   #<OperationalHours:0x00007fa77aa72190 @closing_time="Closed", @notes="", @opening_time="Closed">,
   #<OperationalHours:0x00007fa77aa71f10 @closing_time="Closed", @notes="", @opening_time="Closed">,
   #<OperationalHours:0x00007fa77aa71ce0 @closing_time="Closed", @notes="", @opening_time="Closed">,
   #<OperationalHours:0x00007fa77aa71ab0 @closing_time="Closed", @notes="", @opening_time="Closed">],
 name: "Clear Cut",
 trial_period: 30,
 time_zone: "Central Time (US & Canada)">

And in my active admin file I have:

ActiveAdmin.register Saloon do
  csv do 
    column :name 
    column "Operation Hours" do |sal|
     sal.operational_hours.each do |hour|
      "#{hour.opening_time}-#{hour.closing_time}"
     end
    end
  end
end

But operational hours on CVS has:

[#<OperationalHours:0x00007fcf295e2a90 @opening_time="9:00 AM", @closing_time="5:00 PM", @notes="">,
 #<OperationalHours:0x00007fcf295e2798 @opening_time="9:00 AM", @closing_time="5:00 PM", @notes="">,
 #<OperationalHours:0x00007fcf295e2428 @opening_time="9:00 AM", @closing_time="5:00 PM", @notes="">,
 #<OperationalHours:0x00007fcf295e2158 @opening_time="9:00 AM", @closing_time="5:00 PM", @notes="">,
 #<OperationalHours:0x00007fcf295e1eb0 @opening_time="9:00 AM", @closing_time="5:00 PM", @notes="">,
 #<OperationalHours:0x00007fcf295e1910 @opening_time="9:00 AM", @closing_time="5:00 PM", @notes="">,
 #<OperationalHours:0x00007fcf295e1690 @opening_time="9:00 AM", @closing_time="5:00 PM", @notes="">]

Is there a way to iterate over operational hours and show each as "9:00 AM-5:00 PM"format?

Answer 1

I was thinking wrong all along. For solution, I made a method on the Saloon model to send formatted operational hours.

  def sanitized_operational_hours
    hours = ""
    self.operational_hours.each_with_index do |v, i|
      if i==6
        hours += "#{Date::DAYNAMES[0]} #{v.opening_time} - #{v.closing_time} "
      else 
        hours += "#{Date::DAYNAMES[i+1]} #{v.opening_time} - #{v.closing_time} "
      end
    end
    hours
  end

And on my active admin I called this method

  column "Operational Hours" do |t|
      t.sanitized_operational_hours
  end
