ruby on rails 4 - devise - send_reset_password_ins

问题:

I am using ruby on rails version '4.2.4' and devise 4.0.0

gem 'rails', '4.2.4'
devise (4.0.0)
  bcrypt (~> 3.0)
  orm_adapter (~> 0.1)
  railties (>= 4.1.0, < 5.1)
  responders
  warden (~> 1.2.3)

Taking over some code made from someone, they have implemented reset password but didnt quite work. I am trying to solve it.

from the console, I tried to use this:

> u = User.first
> u.send_reset_password_instructions

this is console output:

[15] pry(main)> u.send_reset_password_instructions

    <p>Hello [e-mail]!</p>

    <p>Someone has requested a link to change your password. You can do this through the link below.</p>

    <p><a href="http://localhost:3000/users/password/edit?reset_password_token=qpkCBYwZzmqprudst1oq">Change my password</a></p>

    <p>If you didn't request this, please ignore this email.</p>
    <p>Your password won't change until you access the link above and create a new one.</p>

    => "qpkCBYwZzmqprudst1oq"

the email is received, however navigating to the page (http://localhost:3000/users/password/edit?reset_password_token=qpkCBYwZzmqprudst1oq) and inserting the new password has this error

1 error prohibited this user from being saved:
Reset password token is invalid

I checked there is some token generated in the User record:

 reset_password_token: "23837a8b05a8249ac4edf5e3e6b6e8f922277ef409e693cd802bc1707b0838b7",
 reset_password_sent_at: Sun, 20 May 2018 04:13:23 UTC +00:00,

this matches the debug output below:

What is the problem, how to debug (like how do i know if the token is correct) and solve this ?

I manage to override Devise::PasswordsController to change the password devise in controller/users/password_controller. However, I want to debug this now, recoverable.rb ? How can I override recoverable.rb ? I want to see how it works in this method:

 def reset_password_by_token(attributes={})
