does not<\/strong> work, and it’s also a Controller.<\/p>\n
Where is the posts_path<\/code> defined?<\/p>\n
    \n
  1. \n
    posts_path<\/code> is a named route you get for free from the route that was added by script\/generate scaffold<\/code>. See routes.rb<\/code> you should see something like this:<\/p>\n
    map.resources :posts\n<\/code><\/pre>\n
    See the API docs for information on what other named routes you get for free.<\/p>\n
    Also you can run rake routes<\/code> and see what all your routes.rb<\/code> is giving you.<\/p>\n
    If you want a home_path named route add a line like this to your routes.rb<\/code>:<\/p>\n
    map.home '\/home', :controller => \"home\", :action => \"index\"\n<\/code><\/pre>\n<\/li>\n
  2. \n
    I believe that “posts_path” is created dynamically by Rails at runtime. Look at your routes.rb file – Home is probably not defined the same way as Posts. It has nothing to do with you controllers, it’s dependent on the route definition.<\/p>\n<\/li>\n
  3. \n
    map.root :controller => \"home\"<\/code> would be a shorter way of writing the path to your home directory. This will use \/ has the home, and not \/home. If you still want to use \/home (and home_path), map.home 'home', :controller => \"home\"<\/code> will do the same thing.<\/p>\n
    There’s a great guide written by Mike Gunderloy about everything there is to know about routing.<\/p>\n<\/li>\n<\/ol>\n
