Are observers still in Ruby?

[jailalawat]

Hi,

First comment the observer line into the file redmine/plugins/systango_hrm/init.rb on line number 13 comment this line

ActiveRecord::Base.observers += [:systango_hrm_compoff_observer, :systango_hrm_designation_history_observer, :systango_hrm_leave_account_observer, :systango_hrm_teamleads_subordinates_observer, :systango_hrm_employee_leave_observer]

because it is not necessary to load in to rails4

and second things to change the line number 21, code in to the file redmine/plugins/systango_hrm/lib/systango_hrm/user_patch.rb

remove -> has_many :self_employee_leaves, :class_name => "SystangoHrmEmployeeLeave", :foreign_key => 'user_id',:conditions => {:referral_id =>nil}, dependent: :destroy

to replace this one

has_many :self_employee_leaves, -> { where(:referral_id =>nil) }, :class_name => "SystangoHrmEmployeeLeave", :foreign_key => 'user_id', dependent: :destroy
