* Added record identification with polymorphic routes for ActionController::Base#url_for and ActionView::Base#url_for [DHH]. Examples:
|
||||
|
||||
redirect_to(post) # => redirect_to(posts_url(post)) => Location: http://example.com/posts/1
|
||||
link_to(post.title, post) # => link_to(post.title, posts_url(post)) => <a href="/posts/1">Hello world</a>
|
||||
|
||||
Any method that calls url_for on its parameters will automatically benefit from this.

* Removed deprecated parameters_for_method_reference concept (legacy from before named routes) [DHH]
|
||||
|
||||
* Add ActionController::Routing::Helpers, a module to contain common URL helpers such as polymorphic_url. [Nicholas Seckar]
|
||||
|

* Included the HttpAuthentication plugin as part of core (ActionController::HttpAuthentication::Basic) [DHH]
