wtf? self != self

console.rb

>> self
=> #<Activity id: 7126, user_id: 58, start_at: "2016-08-02 03:15:00", end_at: "2016-08-02 10:30:00", worked_hours: #<BigDecimal:7fda363efae0,'0.675E1',18(27)>, vacation_hours: #<BigDecimal:7fda363ef950,'0.51975E0',9(18)>, date: "2016-08-02", information: "othertest">

=> #<Activity id: 7126, user_id: 58, start_at: "2016-07-28 02:45:00", end_at: "2016-07-28 10:15:00", worked_hours: #<BigDecimal:7fda369f7bb8,'0.7E1',9(18)>, vacation_hours: #<BigDecimal:7fda369f7a50,'0.539E0',9(18)>, date: "2016-07-28", information: "test2">

Only clues:
@changed_attributes	=> {"id"=>7135}

@original_raw_attributes	=> {"id"=>7126}

#WTF?

controller.rb

User.current_user.activities.order(date: :desc).group_by{|a| [a.date.beginning_of_month, a.status]}

model.rb

class Activity < ActiveRecord::Base
   def status
     
     byebug 
     #see console.rb
     #random code
     #self.something = xyz #not working :)
