option both in named and non-named routes as well as in generated resources routes.
Let's say my domain is 'intridea.com'. Here are some examples of the use of the :subdomain
option:
-url_for(:controller => "my_controller",
- :action => "my_action",
- :subdomain => "awesome") # => http://awesome.intridea.com/my_controller/my_action
+ url_for(:controller => "my_controller",
+ :action => "my_action",
+ :subdomain => "awesome") # => http://awesome.intridea.com/my_controller/my_action
Now let's say I'm at http://awesome.intridea.com/ and I want back to the root.
Specifying "false" will remove any current subdomain:
-users_url(:subdomain => false) # => http://intridea.com/users
+ users_url(:subdomain => false) # => http://intridea.com/users
Note that this plugin does not honor the :only_path notion of routing when doing
so would go against the intent of the command. For example, if I were at http://intridea.com
again:
-users_path(:subdomain => "fun") # => http://fun.intridea.com/users
-users_path(:subdomain => false) # => /users
+ users_path(:subdomain => "fun") # => http://fun.intridea.com/users
+ users_path(:subdomain => false) # => /users
In this way you can rest assured that you will never misdirect your links to the
same subdomain when you meant to change it.
== Use in controllers and views
You have access to current_subdomain and current_domain methods.
-current_subdomain - returns all subdomains.
- Example for the URL http://awesome.website.stuff.example.com current_subdomain will return "awesome.website.stuff"
+[current_subdomain] returns all subdomains. For the URL http://awesome.website.stuff.example.com, it will return "awesome.website.stuff"
-current_domain - returns all subdomains except for the subdomain, including the TLD.

+[current_domain] returns all subdomains except for the subdomain, including the TLD. For the URL http://awesome.website.stuff.example.com, it will return "website.stuff.example.com"
If what you really want is the entire domain, then use <tt>request.domain</tt> in
your controllers. The purpose of current_domain is to only strip off the first
subdomain, if any, and return what's left.

=== TLD Size

=== Preferred Mirror
SubdomainFu also understands the notion of a 'preferred mirror', that is, if you
always want your links going to 'www.yourdomain.com' instead of 'yourdomain.com',
you can set the preferred mirror like so:
-SubdomainFu.preferred_mirror = "www"
+ SubdomainFu.preferred_mirror = "www"

== Routing
