Handling Parameters in Rails

How to validate parameter passed to the controller from view. The following is my view file.

index.html.erb:

<html>
<body>
    <center> <h1> Login form </h1> </center>
    <form action='/login/auth' method='GET'>
        Name: <input type="text" name="username" width=20>
        Password: <input type="password" name="password" width=20>
        <input type="submit" value="login">
    </form>
</body>
</html>

The above is the view file rendered in client side when the client calls '/login' controller. So, once the value is filled and press the submit button, the datas are passed to '/login/auth' action. With in auth method how to handle the data which is passed from client side. My controller file is,

login_controller.rb:

ass LoginController < ApplicationController
  def auth

  end
end

You can get the "username" and "password" parameters from params[:username] and params[:password].

For easy and secure authentication process you can use "devise" gem which is widely used for authentication. It's easy to configure and provides the login and signup view pages by default.

something like this:

if params[:username].present? && params[:password].present? 
  #do something
end
