Rails Check output of path helper from console

Question

Rails defines a bunch of magic with named routes that make helpers for your routes  Sometimes  especially with nested routes  it can get a little confusing to keep track of what URL you ll get for a given route helper method call  Is it possible to  using the Ruby console  see what link a given helper function will generate  For example  given a named helper like post path post  I want to see what URL is generated
