Join Kevin Skoglund for an in-depth discussion in this video Redirecting actions, part of Ruby on Rails 4 Essential Training.
…In this movie, we are going to learn how to redirect actions from the controller.…Controllers can respond to request by rendering a view back to the browser.…The diagram that we have been looking at is deceptive, because it…is the controller's final step must always be to render a view.…But the controller can make a different choice.…They can also perform a redirect instead.…So what is a redirect?…A redirect sends a request to a different controller an action.…Imagine this scenario.…A user requests a page which is in a password protected area.…
The controller checks to see if they are logged in.…And if they are, then they get the page that they wanted.…But if they're not, then they get redirected to a log in page instead.…Then you may be thinking well why not just use render and render the log in page?…But rendering is just rendering the template.…If there's any other code that the log in action needs to perform, any…other housekeeping that it needs to take care of before it can display the form.…Maybe it looks in their cookies to find their user name.…
