SubdomainFu
===========
SubdomainFu provides a modern implementation of subdomain handling in Rails.
It takes aspects from account_location, request_routing, and other snippets
found around the web and combines them to provide a single, simple solution
for subdomain-based route and url management.
Installation
============
SubdomainFu is available both as a traditional plugin and a GemPlugin. To
install it as a traditional plugin (Rails 2.1 or later):
script/plugin install git://github.com/mbleigh/subdomain-fu.git
To use it as a GemPlugin, add it to your environment.rb:
config.gem 'mbleigh-subdomain-fu', :source => "http://gems.github.com", :lib => "subdomain-fu"
Examples
========
SubdomainFu works inside of Rails's URL Writing mechanisms to provide an easy and seamless
way to link and otherwise understand cross-subdomain routing. You can use the :subdomain
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
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
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
In this way you can rest assured that you will never misdirect your links to the
same subdomain when you meant to change it.
Configuration
=============
You may need to configure SubdomainFu based on your development setup. The
configuration required is:
tld_size
--------
A hash for each environment of the size of the top-level domain name.
(something.com = 1, localhost = 0, etc.)
SubdomainFu.tld_size = 1 # sets for current environment
SubdomainFu.tld_sizes = {:development => 0,
:test => 0,
:production => 1} # set all at once (also the defaults)
mirrors
-------
Mirrors are the subdomains that are equivalent to no subdomain (i.e. they 'mirror')
the usage of the root domain.
SubdomainFu.mirrors = %w(www site we) # Defaults to %w(www)
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"
Now when you create a link to a false subdomain
Known Issues / Future Work
==========================
SubdomainFu will eventually integrate with Rails' routing internals to provide
the ability to specify routes based on the condition of a specific subdomain or
simply whether a subdomain is present (or a mirror).
