Rails: How to get URL params without routing parameters (or vice versa)

Posted . Visible to the public.

Rails' params hash contains any request parameters (URL parameters or request payload) as well as routing parameters like :controller, :action, or :id.

To access only URL parameters, use request.query_parameters. Routing params are available through request.path_parameters.

# On /users?query=Bob&page=2

>> request.params
=> {"page"=>"2", "query"=>"Bob", "controller"=>"users", "action"=>"index"}

>> request.query_parameters
=> {"page"=>"2", "query"=>"Bob"}

>> request.path_parameters
=> {:controller=>"users", :action=>"index"}

Note that path_parameters is a Hash with Symbol keys, not a HashWithIndifferentAccess like the other.
