title: Rails -- routing: using a sub-directory before controller/action
body: <p>Say I have an application called employeesmanager, and it has an <code>employees</code> resource, so <code>/employees/new</code> is a new employee etc.  I want to have the name of the company preceding this action, so for example, <code>ford/employees/new</code> should create a new employee at ford, while <code>exxon/employees/new</code> should create a new employee at exxon.  What is the best way to do this?</p>
  
  <p>Ideally I don't want to have to use nested controllers with <code>/company/exxon/employees/new</code> because that seems like extra wasted words in the URL that can be annoying to type in.</p>
