I am running rails 3 version and using attr_encrypted gem version '1.2.1' . sometimes i have seen that nil entry is getting stored into column encrypted_private_key.
Below is my model
class Device < ActiveRecord::Base
attr_encrypted :private_key, :key => proc {|device| device.log }
end
Below is how i am trying to store value in column encrypted_private_key
device = Device.new
device.private_key = "XYZ"
device.save
after doing device.save if i do device.encrypted_private_key then sometimes i am getting nil value. what could be the reason for this? This issue is not coming everytime but sometime.
