I'm trying to work through this guide to Rails routing, but I got stuck in section 3.3:

Creating a RESTful route will also make available a pile of helpers within your application

and then they list some helpers like photos_url, photos_path, etc.

My questions:

Where can I find the complete list of helpers that is "made available?"

Is there a way to call the helpers in the console? I created an app, then opened up the console with script/console. I tried to call one of the helpers on the console like this:

>> entries_url

But got:

NameError: undefined local variable or method `entries_url' for #<Object:0x349a4>
