extending rails via /lib - problems
I wanted to group some functions which I use in some models in one
place. Controllers have application.rb and views have helpers but I
couldn''t find anything about models. Using the /lib directory seemed to
be the only way.
Alright... so I have something like this:
/lib/code.rb
class ActiveRecord::Base
def method_a(n)
.......
end
def method_b(n)
........
end

Object and Classes ?
I found a tutorial for creating classes using generic functions ? S3
way ! It was short description so I couldn't grok in full its
usage ... So far so good, what i currently do is something like this :

When to use Mutex::synchronize?
I have a simple question when to the synchronize method in the Mutex
class.
Now that backgroundrb has allow_concurrency = true there is no need
to synchronize database calls in threads.
The question I have is lets say I have a simple method in my worker
as follows:
def some_method
SomeModel.find_all each do |obj|
obj.some_count += 1
obj.save!
end
end
It accesses the database, but

Ruby class variables and access from view templates
I have an app that requires me to define a class variable (actually an
array) in a controller and then access it from within a view. It seems
that the class variables aren''t working right. Here is an example of
what I''m trying to do.
class DisplayController < ApplicationController
@@thumbnail_array = Array.new
...
def some_method
@@thumbnail_array = SomeModel.find_all

Question about how Mongrel process works with singletons
Hi,
I have a controller where I access a singleton class that I use to
connect to a DRbprocess
DrbConnector.instance.some_method
I notice that on every request, the constructor is called so it is
making a new instance of this singleton. Is this normal?
Thanks,

Accessing the Model class from Controller
Hi,
I wonder if there''s an easy way to access the associated Model class
from its Controller. Something that would allow me to write snippets
like the following:
class PeopleController < ApplicationController
def some_method
person_model_class =
self.some_method_to_retrieve_the_person_model_class()
end
end
Cheers,

How to deserialize an array from XML
Hi,
to serialize an array to xml we can use:
an_array = [ 1, 2, 3]
an_array.to_xml
But to I can''t find a way to convert back XML to array. I didn''t find a
method Array.from_xml like Hash.from_xml.
Any ideas?
Thanks,

Associations and Math between Models

has_and_belongs_to_many. I''m trying to get an attribute from model_1 to use

Passing objects to drb, does it keep the existing db connection?
I have a simple question. Let''s say I do this in one of my models:
after_save
drb_conn.some_method(self)
end
When that object gets over to the background process is it the exact
same as?....
Model.find some_id #in the background process
As far as my background process is concerned passing the object is
not any different than passing the id and using the find method?

Best way to execute timed actions?
I''ve seen this come up a few times before on this list but never felt
it got a satisfactory answer. What is the best way to execute timed
actions? Examples include sending an email each week, calculating
interest each day, or cleaning up your database or server files.
This wiki page has some ideas, but these seem a bit extreme.

calling a controller/action from another controller
Hi,
Is there a way to call a controller/action pair from another controller
as well as render the view for that pair? I have tried using "render
''ctrl/action''" and that works, but the controller code isn''t called
(only the view is rendered). A redirect_to isn''t desirable either as I
want the resulting content to be rendered in the current

fixrbconfig - does it work on intel macs?
I''m trying now to do "sudo fixrbconfig" in the terminal, and I get this:

Why does no one like render_component?
Maybe I''m missing the point?
Lets take for example albums of pictures. If I have a scaffold for
each, and I''m showing an album, what if I want to list all of the
pictures that are in the album?
Surely, I''d want to call the List action in the picture controller.
render_component would do this perfectly. But we''re told not to use
render_component. So

state_models plugin and file_column?
I was looking at Kyle Mawell''s extremely nifty-looking StateModels
plugin
http://www.kylemaxwell.com/articles/2006/02/06/fun-with-single-table-inheritance
and before I go down the road with it, I was wondering if anyone has
used it with file_column.
The way file_column deals with an uploaded file -- by storing it to the
filesystem in a path that employs the model name and id --
