I want to list all defined helper path functions (that are created from routes) in my rails 3 application, if that is possible.
Thanks,

Solution 1 - Ruby on-Rails
rake routes
or
bundle exec rake routes
Solution 2 - Ruby on-Rails
##Update
I later found that, there is an official way to see all the routes, by going to http://localhost:3000/rails/info/routes. Official docs: https://guides.rubyonrails.org/routing.html#listing-existing-routes
Though, it may be late, But I love the error page which displays all the routes. I usually try to go at /routes (or some bogus) path directly from the browser. Rails server automatically gives me a routing error page as well as all the routes and paths defined. That was very helpful :)
So, Just go to http://localhost:3000/routes

One more solution is
Rails.application.routes.routes

Solution 4 - Ruby on-Rails
Trying http://0.0.0.0:3000/routes on a Rails 5 API app (i.e.: JSON-only oriented) will (as of Rails beta 3) return
{"status":404,"error":"Not Found","exception":"#>
<ActionController::RoutingError:...
However, http://0.0.0.0:3000/rails/info/routes will render a nice, simple HTML page with routes.
Solution 5 - Ruby on-Rails
rake routes | grep <specific resource name>
displays resource specific routes, if it is a pretty long list of routes.
Solution 6 - Ruby on-Rails
CLI
updated for version 6
To list all existing routes you'll want to run the command:
bundle exec rails routes
bundle exec will
> Execute a command in the context of the bundle
and rails routes will
> list all of your defined routes
Example
If you have your resource route declared like so:
resource :credential, only: [:new, :create, :destroy]
Then it's helpful to pipe the output so you can grep for your specific resource.
For example:
