devise save user causes reset_password_token to be set to nil

Question

This just started happening, I am not sure when or what caused it, but for some reason devise is clearing my reset_password_token on save.

In order to debug my problem, I implemented

  def reset_password_token=(token)
    debugger
    self[:reset_password_token] = token
  end

on my User object so I could see who was setting it.

Whenever I do user.save(), my reset_password_token gets set to nil, here is the callstack:

In devise I see this:

 if email_changed? || encrypted_password_changed?
        clear_reset_password_token
 end

If this is true, how am I supposed to set the token and create the user at the same time. The work around I found is after the save to set just the token and that seems to have worked, but not sure why this just started happening..

Answer 1

Just dealt with this and came here for advice. After some fiddling and testing, my solution was simply to perform a save on the object to clear the _changed? log. I do this in after_create for the User:

def email_credentials
    self.save
    self.send_reset_password_instructions
end

Answer 2

I meet the same issue. It seems that the only solution is to save the user before set reset_password_token

user = User.new
user.email = 'test@example.com'
user.save # save
user.reset_password_token = 'token'
user.reset_password_sent_at = Time.now.utc
user.save # save again
