Scalable alternative to #find_all
Is there any scalable alternative to iterating all the records of a
certain model? #find_all seems to load everything into memory. With
500.000 records it will be a swap storm.

Separate Read and Write Database
Hello,
I need to access an mirrored database with one read and one write
cluster. Is there a way to tell a model to use two connections? So that
all updates etc go to the write database and all read from the read one?
This is a fixed set up I can not use MySQL 5.x stuff and additionally i
get a token on write, which can be checked on read (and wait for
replication) if new data is needed.

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

what I''m trying to do.
class DisplayController < ApplicationController
@@thumbnail_array = Array.new

List of all Models
Anyone know a pretty way to get a list of all Models?
That is, a list of all classes which inherit from ActiveRecord:Base
I can''t seem to figure it out!
The best I''ve got is to list the /app/models directory... but, that is
*dirty*.

rake db:migrate
Would it make sense for rake db:migrate to support creating databases if
it is not found, with blessing from user to prevent typos, or as an
additional command line switch.
Or am I just being too lazy?

question about how to set up an active record adapter to prefer use of prepared statements...
Hi,
I am writing an active record adapter for our new database and when I run
the tests I see lots of statements that could be run as prepared
statements, but instead of passing me bindings AR passes me a fully
specialized SQL string, not in all cases, but in many. Here is an example:
SELECT addrs.* FROM addrs WHERE addrs.user_id = 153 FETCH FIRST 1 ROWS ONLY

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:

I am working on a app right now that is going to replace a paper form

Set default order for find(:all) in a model
Hi everyone
Is there a way that I can get the find(:all) method to return in a specified
order, without including the :order argument every time?
Guess I just don''t like typing...
