Rails: how do you access RESTful helpers?

Question

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>
    from (irb):8

Solution 1

You have several questions in there, most of which have already been answered by people below.

The answer to one that wasn't fully addressed however, is: yes you can use the script/console to see where your routes go. Just type in app.[route_helper] and it will respond with the path. For example app.users_path will return /users/

So for your example type app.entries_url for the full URL - or app.entries_path for its relative path within the console.

Solution 2

rake routes at the command line should get you that list.

Solution 4

You can access other helpers in the console by prepending "helper."; ie. helper.progress_box (assuming #progress_box exists of course)

Take the first column and append _url to have the full URI or _path to have an URI not including the domain name.

Is there any way to generate a list of helpers, with _url and _path and parameters written explicitly? Would be most helpful in the case of nested resources, to see clearly what parameters each helper takes, if any.

the extra anchovies is that it does tab completion, e.g., at the console type app.edit[tab] and it lists all routing helper methods beginning with 'edit'.
