Just a copy from Active Record (with tests). Each is a warpper function for
the equivalent scoped call to find eg first is a wrapper for find(:first)

Similar to Active Record - it will raise ActiveResouce::ResourceInvalid if
the resource is not valid (ie if <tt>valid?</tt> returns false)

However - does not raise ActiveResource::ResourceNotFound if the callbacks
fail (callbacks have not yet been implemented) - it will just try to save
and raise if the callbacks all fail.

This is not ideal behaviour - but will do until we decide to change the
behaviour of save_with_validations to actually raise (rather than catch) the
ResourceInvalid exception.

Active Record does not explode with RecordNotFound if you go looking for a
collection of objects - it just returns nil. Thus Active Resource should
also not explode.

After all - finding no objects that match a set of conditions is not
exceptional behaviour - unlike looking for a specific object with a given id
(which you'd expect to exist).

I've also added documentation to +find+ to reflect this.

Pulled find-based tests into their own test case. This matches Active Record, and allows us to have one places where all find-tests are located, which will help when adding dynamic finders later.

Moved all test cases into a new test/cases directory to match Active Record test directory structure.

Added validations to ActiveResource. Added a smoke test to see if we can add a validation and use it, and add a validates callback and use it.

If you're still using it, please install the plugin from git://github.com/rails/sqlite2_adapter.git

Cleanup route reloading in tests. Prefer with_routing over using ActionController::Routing::Routes directly

Adding a call to logger from params_parser to give detailed debug information when invalid xml or json is posted

  * request.formats is much simpler now
    * For XHRs or Accept headers with a single item, we use the Accept header
    * For other requests, we use params[:format] or fallback to HTML
    * This is primarily to work around the fact that browsers provide completely
      broken Accept headers, so we have to whitelist the few cases we can
      specifically isolate and treat other requests as coming from the browser
    * For APIs, we can support single-item Accept headers, which disambiguates
      from the browsers
  * Requests to an action that only has an XML template from the browser will
    no longer find the template. This worked previously because most browsers
    provide a catch-all */*, but this was mostly accidental behavior. If you
    want to serve XML, either use the :xml format in links, or explicitly
    specify the XML template: render "template.xml".

Caches and cache clearing seems to actually work, but the actual architecture is kind of messy. Next: CLEAN UP.

  * only one of partial_name or :as will be available as a local
  * `object` is removed
  * Simplify _layout_for in most cases.
    * Remove <% render :partial do |args| %>
    * <% render :partial do %> still works fine

  * Call _evaluate_assigns_and_ivars at the two entry points so we don't have to
    do a check at every render.
  * Make template.render viable without having to go through a wrapper method
  * Remove old TemplateHandler#render(template, local_assigns) path so we don't have
    to set self.template every time we render a template.
  * Move Template rescuing code to Template#render so it gets caught every time.
  * Pull in some tests from Pratik that test render @object in ActionView
