NoMethodError - undefined method `reset_password_token' for User:Class:

问题

In my Rails application, I have a form for admin to create normal users. In create action, I am generating a reset password token, and sending a welcome mail to the user, with a link in it to reset his password. This is my code.

@user = User.new params[:user]
@user.reset_password_token = User.reset_password_token
@user.reset_password_sent_at = Time.now.utc
if @user.save
  UserMailer.welcome_email(@user).deliver
  ..

This works fine, but I have another app with the same code, but uses devise 3.2.2 in which I get the this error.

NoMethodError - undefined method `reset_password_token' for User:Class:

I see that the method has been removed. How can I generate a reset password token and send it to a user?

Note: I don't want to send the default reset password email

回答1:

After a lot of digging into devise's source code, I got it to work by doing this.

raw, enc = Devise.token_generator.generate(User, :reset_password_token)
@user.reset_password_token = enc
@user.reset_password_sent_at = Time.now.utc
if @user.save
  UserMailer.welcome_email(@user, raw).deliver
  ..

Use raw as the reset_password_token
