In a Rails app, which statement can be used to send the user to a different page?

a. route_to

b. redirect_to

c. continue_to

d. send_to

The correct answer and explanation is:

Correct Answer: b. redirect_to

In a Ruby on Rails application, the correct method to send the user to a different page is redirect_to. This method is used in controllers to perform an HTTP redirect, which tells the browser to make a new request to a different URL. It is a common part of the Post/Redirect/Get pattern, which is used to avoid duplicate form submissions and to improve user experience.

For example, after a user successfully submits a form to create a new resource, you might want to redirect them to the show page of that resource:

redirect_to @article

This line sends the browser to the page that displays the newly created article. Alternatively, you can redirect to a specific URL or named route:

redirect_to "/welcome"
redirect_to articles_path

The redirect_to method works by returning a 302 Found HTTP status code by default, unless otherwise specified. This tells the client’s browser to initiate a second request to the new location.

The other options in the question are incorrect:

• route_to is not a valid Rails method. Routes are defined in the routes.rb file, but they are not used this way in controllers.
• continue_to does not exist in Rails. It is not part of the framework’s redirection or routing system.
• send_to is also not valid in Rails for redirection. While send is a Ruby method used to call methods dynamically, it is unrelated to routing or HTTP behavior.

Thus, redirect_to is the correct and widely used method to navigate users between different pages in a Rails app.
