# Simple Constraints

Routing constraints are automatically included in the Rails router.

## Installation

Add this line to your application's Gemfile:

gem 'simple-constraints'

And then execute:

$ bundle

### Subdomain

The `subdomain` constraint allow you to specify routes that should only
be applied for certain subdomains. The `:only` option will only match
the subdomains given, the `:except` option won't match the given
subdomains. There is also a `:tld_length` (should be `1` for `.com`, `2`
for `.co.uk` etc) which defaults to 1.

```ruby
My::Application.routes.draw do
subdomain only: 'blog' do
resources :posts
end

subdomain except: ['www', 'mail'] do
resources :spaces
root to: 'spaces#index'
end

root to: 'pages#home'
end
```
