Controllers can redirect requests to a different action. This can happen at any point in the handling of the requests. A redirect is actual a brief response to the web browser asking the browser to issue a new request to a different URL. That URL can be local or remote. Even though the redirect takes place very quickly, it is is important to realize that it is actually a new request to the Rails application.
- [Instructor] In this movie, we'll learn how to…redirect actions from the controller.…Controllers can respond to requests by rendering a view…back to the browser.…But the diagram that we've been looking at is deceptive…because it appears that the controller's final step…must be to render a view.…But it can also make a different choice,…and that is to perform a redirect instead.…Redirects send a request to a different…controller and action.…Imagine this scenario; a user requests a page…which is inside a password protected area,…so the first thing the controller's gotta do…is check to see if the user is logged in or not.…
If the user is logged in, then it will let them have…the page that they wanted, but if not,…then the controller wants them to log in first,…and so it redirects them to a login page instead.…We could use render to render that login page,…but that would just be rendering the login template.…What we really want is to send the user…to the new URL for the login page…and run any controller action code that's associated with it…
