A simple gem for helping coordinate moving a user through a set of routes. The gem uses a token to keep track of the current place in the funnel. The simplest way to use that token is by including a module into the controller and passing the token in the route. However since the token is simply a string it can easily be kept in session or any other datastore if needed.
Add this line to your application's Gemfile:
And then execute:
Or install it yourself as:
$ gem install funneler
Add the gem to your web application. The gem is not dependent upon any particular framework. It's only dependency is the [
Generate a token for a given set of routes, and route your user to the first page:
funnel = Funneler.build(routes: ['/welcome', '/setup', '/complete']) redirect_to funnel.first_page
Modify those pages to include the
Funneler::ControllerMethodshelper for reconstituting a funnel from the given token
Use the helper to determine the next page like this:
<%= link_to funnel.next_page, "Next" %>
Funneler::Funnel is the core maintaining the state of the flow of
pages and building the paths with valid tokens.
