Rails - Jan 2005 - Rails 0.9.4: Caching, filters, SQLite3…

Another incredibly strong release sees the light of day as we move one 
step closer to the mythical 1.0. This release tackles one of the five 
steps on the roadmap in form of caching as well as adding a bunch of 
other cool stuff.

* *Render Caching:* Added an extensive caching module that offers three 
levels of granularity (page, action, fragment) and a variety of stores 
(file, memory, DRb, MemCached).

* *Conditional filters:* It''s now possible to limit the actions that a 
given filter will apply to within a controller using either :only or 
:except. Like, <code>before_filter :authorize, :only => [ :edit, 
:delete ]</code>

* *Associating unsaved objects:* Associations between unsaved objects 
makes it much easier to build big graphs that only makes sense to be 
saved together.

* *Database compatibility:* SQLite3 is now supported by the sqlite 
adapter and MySQL 4.1.1+ is also supported by the included Ruby/MySQL 
driver.

* *Numeric bytes and time:* Rails has taken upon itself to extend Ruby 
in a few spots, such as adding the possibility for expressions like 
<code>45.kilobytes + 2.3.megabytes</code> and <code>45.minutes
+
2.hours + 1.fortnight</code>.

Those were the highlights, but Rails 0.9.4 includes no less than 50 
changes, fixes, and features. You can read the full story in the 
changelogs:

* Active Record: http://ar.rubyonrails.com/files/CHANGELOG.html
* Action Pack  : http://ap.rubyonrails.com/files/CHANGELOG.html
* Rails        : http://rails.rubyonrails.com/files/CHANGELOG.html

This release shouldn''t require any changes to your application if 
you''re coming from Rails 0.9.3.

Hmm, the caching in actionpack 1.3.0 seems to have a bug.

Where can I report this?

The following line seems to be incorrect: (i''m running gems rails)

action_controller/caching.rb:124
it says: !@request.method.post? && ... and gives a method not found for
:get:Symbol error

by changing this line to:
!@request.post? && ...

the bug seems to be fixed.

Kind Regards,
Flurin

Thanks for spotting it. It has been fixed and new beta gems published. 
Seems like we caught a few snags pushing out 0.9.4, so 0.9.4.1 will 
make it out later today.

No changes in ActiveMailer ?

My application is not getting an error from TMail when trying to send
mail...

controllers/bada_controller.rb:
-----
  def submit
    @missing = check_for_mandatory(@params)
    if @missing.length != 0 then
      render "/bada/registration"
    else 
      Notification.server_settings[:address] = "relay.eurocontrol.fr"
      Notification.server_settings[:domain] = Host.hostname
      Notification.deliver_form_data(@params)
      render "/bada/form_ok"
    end
  end
end

models/notification.rb:
-----
  def form_data(parameters)
    @recipients = BCC
    @from = FROM
    @to = RECIPIENTS
    @headers[''bcc''] = BCC.to_s
    @headers[''user-agent''] = "Rails/bada-1.0"
    @subject = "New BADA request from
#{parameters[''l_name'']} by
#{parameters[''a_email'']}"
    @body = parameters.dup
  end
end
