FatWreck.com - New Rails Site
After months of design and development, we''ve launched our second Rails
site, http://www.fatwreck.com (assuming your DNS is updated - the pink site
is the old one).
The site is for legendary punk rock record label, Fat Wreck Chords and it
includes a store.
The old site was highly trafficked, with millions of page views per month
and we expect this one to be also. So far, the server

Postgresql vs MySQL
Is there any reason to avoid using postgresql for small web apps? That is, is it''s
overhead so large that the lighter MySQL will work substantially better for small apps on
small machines? Or are they very similar in performance and configuration?
I''ve used MySQL but postgresql has its appeals and I''m wondering if I need to keep MySQL
around at all.

script/console
The agile book says "You can inspect variables, set values, add other
breakpoints, and generally have a good time".
This is very sweet and totally useless. For example, I want to see the session variable,
the cookies variable and so on. These names are unknown. I think I guess that the things
that are available depend on where you put the breakpoint() call. I''ve tried a

actions with no views?
In Depot, the demo application in the the Agile book, actions that
modify the model such as add_to_cart redirect to another action that
has a clear view role, like index, or show_cart, instead of
generating the view themselves. This uses an HTTP redirect that goes
to the client and returns.
Is this an idiomatic way to design the flow in Rails?

best practice for object transaction?
I have a new @offer that needs to generate a document if saved. But
that''s all or nothing:
transaction do
@offer.save!
generate_document
end
# handle exceptions if needed
If save! fails everything is fine, but if generate_document raises an
exception @offer is left as a model with timestamps, id, which is not
a new_record? anymore (though the database was

SQLite in-memory
I left ":memory:" in database.yml for testing and the most simple
tests in the Agile book do not work (see trace below for test_truth).
Since that''s what comes with the distributed database.yml I suppose
it''s me doing something wrong.
Did someone get SQLite ":memory:" working? How does it grab the schema?

migrations and SQLite
I read in the instructions of Tracks that "upgrading via the rake
migrate command is quite a bit more tricky currently with SQLite and
SQLite3". Is there any gotcha regarding migrations and SQLite3?

compress and max upload size?
I am using mongrel_cluster with mod_proxy_balancer and would like to
enable compression (assuming it improves throughtput) and limit file
size upload. I configured mod_deflate and LimitRequestSize in Apache,
but in my trials looks like the proxied calls bypass those directives
(the conf goes below).
Is there a way to get this?

rescue_from issue with AWS - uninitialized constant
The new rescue_from in edge rails seems to conflict with
ActionWebService, which I need for various other purposes. When I
define, for example (with AWS gem installed):
<b>rescue_from ActionController::RoutingError, :with

I get the exception:

quantic phenomena in migrations
I have an application with 15 migrations under version control. In a
Mac and and in a Windows, a rake migrate from scratch runs them all
just fine. But in a different Windows machine rake migrate stops
after migration 3 for no apparent reason. --trace seems normal. No
error is reported. Both Windows are XP SP2. They all have the same

History plugin
Hello,
I felt annoyed enough when having to redirect user back to their
previous location in a hackish way that I wrote this plugin.
It avoids storing POST and Ajax request. It also has a facility to
specify actions not to store in the history.
If you are interested, it''s there:

See you all,

"Rails recipes" vs "Rails cookbook"
Reviews Wanted.
I''ve read the tables of contents and haven''t yet made up my mind.
Is one book clearly better than the other? Is one clearly full of bugs? Is one so much
further ahead that there is no choice? Are they both so incomplete that I should just
wait and only cook real food? Do trains still have dining cars?

Is this a bug in Ajax handling?
When a controller responds to a link_to_remote with a redirect_to, the
link_to_remote gets a success callback, this would seem like a bug to
me, at a minimum it should return a failure?
This is driving me crazy because all the login engines/generators
respond to an authentication error with a redirect_to. The work around
is to change them to all do a

SQLite primary key schema
So after successfully getting the test SQLite db to run from memory, I
tried running some tests but found that somewhere in the schema
translation from Postgres (my devel database) and SQLite Rails fails
to properly set the ''id'' column, which breaks all kinds of things.
Take as an example my ''users'' table. In Postgres the schema is

after_(read|find) callback?
I am pondering the possibility of encrypting/decrypting some fields
in a SQLite backend on-the-fly.
The point of the message is not security, I know that''s broken, but
whether there''s a technique that provides on-the-fly save/read
filters. Of course the solution would need to work transparently in
joins, so
user.posts.last.title
would do the right thing if title
