Hello, anyone can help me with how to build a simple user registration form using Rails from scratch, with the fields Login Name, Name, Address and Password (encrypted)? I will be using MySQL to host the database.

I've already created the new project using: rails new reg_form, now what next??

Good call getting started — a single User model plus the MySQL adapter and bcrypt will do the job. already found a solid tutorial path; 's OAuth suggestion is useful when you want social login (Google/Facebook) but is not needed for a simple local registration with encrypted passwords.

Minimal workflow (modern Rails; adapt commands for older versions):

  • Add mysql2 and bcrypt to your Gemfile and run bundle install.
  • Generate a user model with a password_digest column (required by has_secure_password) and run migrations:
rails generate model User login_name:string name:string address:text password_digest:string
rails db:create db:migrate

Model and controller basics (remember: has_secure_password needs the bcrypt gem and password_digest):

class User < ApplicationRecord
  has_secure_password
  validates :login_name, presence: true, uniqueness: true
end
class UsersController < ApplicationController
  def new
    @user = User.new
  end

  def create
    @user = User.new(user_params)
    if @user.save
      redirect_to root_path, notice: "Account created"
    else
      render :new
    end
  end

  private

  def user_params
    params.require(:user).permit(:login_name, :name, :address, :password, :password_confirmation)
  end
end

Simple form (use form_for on older Rails; form_with is preferred now):

<%= form_with(model: @user, local: true) do |f| %>
  <%= f.text_field :login_name %>
  <%= f.text_field :name %>
  <%= f.text_area :address %>
  <%= f.password_field :password %>
  <%= f.password_field :password_confirmation %>
  <%= f.submit "Register" %>
<% end %>

Troubleshooting & notes:

  • If migrations fail, check database.yml and make sure mysql2 and MySQL client libraries are installed on your system.
  • Forgetting password_digest or bcrypt produces authentication errors.
  • For full-featured auth (confirmations, reset, locking) consider Devise later; combine Devise with OAuth for social logins if needed.
