otp_secret is not being saved for preexisting data

[yininge]

I have a User table that has preexisting data, and I start using otp-jwt recently.
It is not working at the beginning because otp_secret column is always empty for preexisting User record

The active record does give the User record a default otp_secret

otp-jwt/lib/otp/active_record.rb

Lines 79 to 81 in 37ca55c

	def setup_otp
	self.otp_secret ||= ROTP::Base32.random_base32
	self.otp_counter ||= 0

My workaround is to go through each user record and save the default otp_secret

User.all.each do |u|
  u.save()
end

Not sure whether we can make it better by updating the documentation, or always save the default secret if there are otp_secret column is empty

@yininge, thanks for reporting this, you're right, the otp_secret values need to be stored first.

I like the documentation suggestion. If you have time, I'll be happy to merge an update for the readme, if not, I'll try to do it in the next days.

🙇‍♂️
