In the “Ruby on Rails tutorial” website:
http://railstutorial.org/chapters/filling-in-the-layout#sec:rails_routes,
section 5.2.2: Rails routes, it was mentioned that:
match ‘/about’, :to => ‘pages#about’
Creates the following “named routes” for use in the controllers and
views:
about_path => ‘/about’
about_url => ‘http://localhost:3000/about’
After that, in section 5.2.3: Named routes:
“#” in: <%= link_to “About”, ‘#’ %>
Was replaced by: <%= link_to “About”, about_path %>
From this thing, why did I use “about_path” here and NOT “about_url”?
Are they differeny then?
So, does “about_path” denote the controller’s “action”?
Thanks.

As you seem to have already discovered, the _url helper contain the
domain,
while the _path helpers do not.
In this case, how do we read:
match ‘/about’, :to => ‘pages#about’
I mean, what does the preceding statement say? Where is the URL here?
Thanks.

Thanks Tim.
So, it is right that _path denotes that action?

The host and protocol bit are are about allowing the browser to talk
to the right url - once the request has made it to your server, only
the path matters (unless you’ve got some account as subdomain stuff
going on)
A lot of the time in your app you only need the _path helpers, because
you’re just linking between pages in your app (although it wouldn’t
hurt to use the _url helpers). Sometimes you need a full url (eg for
putting links in an email) and so those helpers are there too.
