[ANN] Rails 0.9.2: End of requiring models, models in sessions, fixes

Thanks to the powers of const_missing, you no longer need to explicitly 
require models that reside in their own files. They値l spring to life 
automatically, which is very helpful for inheritance where you池e 
documenting the dependency using subclassing already and for instant 
use of models in script/console. It痴 now also safe to place models in 
sessions without worrying about stale association caches葉hey池e 
cleared at the end of each request. In addition, there are about 33 
other fixes, changes, and features in this release.

Update your Rails through gems with "gem install rails"


Rails 0.9.2
===========

* Fixed CTRL-C exists from the Breakpointer to be a clean affair 
without error dumping [Kent Sibilev]

* Fixed "rake stats" to work with sub-directories in models and 
controllers and to report the code to test ration [Scott Baron]

* Added that Active Record associations are now reloaded instead of 
cleared to work with the new const_missing hook in Active Record.

* Added graceful handling of an inaccessible log file by redirecting 
output to STDERR with a warning #330 [rainmkr]

* Added support for a -h/--help parameter in the generator #331 
[Ulysses]

* Fixed that File.expand_path in config/environment.rb would fail when 
dealing with symlinked public directories [mjobin]

* Upgraded to Action Pack 1.1.0 and Active Record 1.3.0


Active Record 1.3.0
===================

* Added a require_association hook on const_missing that makes it 
possible to use any model class without requiring it first. This makes 
STI look like:

     before:
       require_association 'person'
       class Employee < Person
       end

     after:
       class Employee < Person
       end

   This also reduces the usefulness of Controller.model in Action Pack 
to currently only being for documentation purposes.

* Added that Base.update_all and Base.delete_all return an integer of 
the number of affected rows #341

* Added scope option to validation_uniqueness #349 [Kent Sibilev]

* Added respondence to *_before_type_cast for all attributes to return 
their string-state before they were type casted by the column type. 
This is helpful for getting "100,000" back on a integer-based 
validation where the value would normally be "100".

* Added allow_nil options to validates_inclusion_of so that validation 
is only triggered if the attribute is not nil [what-a-day]

* Added work-around for PostgreSQL and the problem of getting fixtures 
to be created from id 1 on each test case. This only works for 
auto-incrementing primary keys called "id" for now #359 [Scott Baron]

* Added Base#clear_association_cache to empty all the cached 
associations #347 [Tobias Luetke]

* Added more informative exceptions in establish_connection #356 
[bitsweat]

* Added Base#update_attributes that'll accept a hash of attributes and 
save the record (returning true if it passed validation, false 
otherwise).

     Before:
       person.attributes = @params["person"]
       person.save

     Now:
       person.update_attributes(@params["person"])

* Added Base.destroy and Base.delete to remove records without holding 
a reference to them first.

* Added that query benchmarking will only happen if its going to be 
logged anyway #344

* Added higher_item and lower_item as public methods for acts_as_list 
#342 [Tobias Luetke]

* Fixed that options[:counter_sql] was overwritten with interpolated 
sql rather than original sql #355 [bitsweat]

* Fixed that overriding an attribute's accessor would be disregarded by 
add_on_empty and add_on_boundary_breaking because they simply used the 
attributes[] hash instead of checking for @base.respond_to?(attr.to_s). 
[Marten]

* Fixed that Base.table_name would expect a parameter when used in 
has_and_belongs_to_many joins [Anna Lissa Cruz]

* Fixed that nested transactions now work by letting the outer most 
transaction have the responsibilty of starting and rolling back the 
transaction. If any of the inner transactions swallow the exception 
raised, though, the transaction will not be rolled back. So always let 
the transaction bubble up even when you've dealt with local issues. 
Closes #231 and #340.

* Fixed validates_{confirmation,acceptance}_of to only happen when the 
virtual attributes are not nil #348 [[e-mail]]

* Changed the interface on AbstractAdapter to require that adapters 
return the number of affected rows on delete and update operations.

* Fixed the automated timestamping feature when running under Rails' 
development environment that resets the inheritable attributes on each 
request.


Action Pack 1.1.0
=================

* Added search through session to clear out association caches at the 
end of each request. This makes it possible to place Active Record 
objects in the session without worrying about stale data in the 
associations (the main object is still subject to caching, naturally) 
#347 [Tobias Luetke]

* Added more informative exception when using helper :some_helper and 
the helper requires another file that fails, you'll get an error 
message tells you what file actually failed to load, rather than 
falling back on assuming it was the helper file itself #346 [dblack]

* Added use of *_before_type_cast for all input and text fields. This 
is helpful for getting "100,000" back on a integer-based validation 
where the value would normally be "100".

* Added Request#port_string to get something like ":8080" back on 8080 
and "" on 80 (or 443 with https).

* Added Request#domain (returns string) and Request#subdomains (returns 
array).

* Added POST support for the breakpoint retries, so form processing 
that raises an exception can be retried with the original request 
[Florian Gross]

* Fixed regression with Base#reset_session that wouldn't use the the 
DEFAULT_SESSION_OPTIONS [[e-mail]]

* Fixed error rendering of rxml documents to not just swallow the 
exception and return 0 (still not guessing the right line, but hey)

* Fixed that textilize and markdown would instantiate their engines 
even on empty strings. This also fixes #333 [Ulysses]

* Fixed UrlHelper#link_to_unless so it doesn't care if the id is a 
string or fixnum [zenspider]
