Password reset email using Rails devise is not changed

Question

Assumption

I am sending an email to reset my password using devise token auth . I was able to send the email, but I am unable to change the email template. I have tried everything but could not solve the problem, so I am asking this question.

What we want to solve

I want to change the email template to allow access to the link.

Code

routes

  namespace :api do
    namespace :v1 do
      ・
　　　　　　　　　　　　・
　　　　　　　　　　　　・
      namespace :auth do
        resource :passwords, only: [:create, :update]
      end

/models/user.rb

# frozen_string_literal: true
class User < ActiveRecord::Base
  # Include default devise modules. Others available are:
  # :confirmable, :lockable, :timeoutable, :trackable and :omniauthable
  has_many :posts, dependent: :destroy
  has_many :schedules, dependent: :destroy
  devise :database_authenticatable, :registerable,
         :recoverable, :rememberable, :validatable
  include DeviseTokenAuth::Concerns::User

controllers/api/v1/auth/passwords_controller.rb

class Api::V1::Auth::PasswordsController < ApplicationController
  skip_before_action :authenticate_api_v1_user_from_token!, only: [:create], raise: false
  def create
    user = User.find_by(email: create_params[:email])
    user&.send_reset_password_instructions
    render json: {}
  end

  def update
    user = User.reset_password_by_token(update_params)
    render json: user, status: :ok
  end

  private
    def create_params
      params.require(:user).permit(:email)
    end

    def update_params
      params.require(:user).permit(:password, :password_confirmation)
    end
end

/views/devise/mailers/reset_password_instructions.html.erb

<p>Hello <%= @resource.email %>!</p>

<p>
test
</p>

<p>
  <%= link_to 'Change my password', "http://localhost:8080/user/edit/newPassword?token=#{@token}"%>
</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>

If you don't remember this content, please ignore this email.

Your current password will not change until you access the link above to create a new password.

What we have tried

I added a setting and changed the template used, but it did not change

/app/mailrs/devise_my_mailer.rb

class DeviseMyMailer < Devise::Mailer
  default template_path: 'devise/mailers'
end

/config/initializers/devise.rb

・

・ 
config.mailer = 'DeviseMyMailer'  

Answer 1

Follow the steps below to override Devise views. I would also recommend checking their documentation about overriding too.

Step 1

rails generate devise:views

Step 2 Add the following line under config/initializers/devise.rb

config.scoped_views = true

Step 3

Find the Devise views under devise/sessions/new and override them.
