Question

Here is my user model

 class User < ApplicationRecord
 
  # Include default devise modules. Others available are:
  # :confirmable, :lockable, :timeoutable, :trackable and :omniauthable
  devise :database_authenticatable, :registerable,
         :recoverable, :rememberable, :validatable
enum role: { Buyer: 0, Seller: 0 } 
end

Here is the routes .

    Rails.application.routes.draw do
  devise_for :users
 
  root 'home#homepage'
  get 'dashboard', to: 'home#dashboard'
end

Here is my my registration form

    <h2>Sign up</h2>


<%= form_for(resource, as: resource_name, url: registration_path(resource_name)) do |f| %>
  <%= render "devise/shared/error_messages", resource: resource %>

  <div class="field">
    <%= f.label :email %><br />
    <%= f.email_field :email, autofocus: true, autocomplete: "email" %>
  </div>

  <div class="field">
    <%= f.label :password %>
    <% if @minimum_password_length %>
    <em>(<%= @minimum_password_length %> characters minimum)</em>
    <% end %><br />
    <%= f.password_field :password, autocomplete: "new-password" %>
  </div>

  <div class="field">
    <%= f.label :password_confirmation %><br />
    <%= f.password_field :password_confirmation, autocomplete: "new-password" %>
  </div>
  <%= f.label :role %>
  <%= f.select :role, User.roles.keys %>

  <div class="actions">
    <%= f.submit "Sign up", data: {turbo: false} %>
  </div>
<% end %>

<%= render "devise/shared/links" %>
