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?

distributing iconv.dll
I would like to distribute Iconv for Windows with my Rails
application (developing on a Mac, no experience with dlls). I threw
iconv.dll and charset.dll under lib without luck. Where would I need
to put them (if this is possible at all)?
-- fxn
PS: The reported error message is in Spanish but translated reads
something like "the specified process was not found: Init_iconv".

Inserting datetime value into SQL Server
I have a SQL Server column named StartTime of (SQL Server) type datetime

end
it''s inserting a NULL value.

when is model() needed?
I have just some vague and thus probably wrong ideas about when to
use model() in controllers, and by now I err on being redundant. I
don''t post them here to avoid leaving anything that may be false in
the archives.
Can anyone explain exactly in which cases one should use model()?

elemental race conditions question
What''s the standard way to prevent race conditions in controllers?
Say user has many posts.
Post controller has action add_post that receives user id, post
controller find()s the user and while he is creating the post entry
an administrator deletes that user in a separate session. We cannot
assume the database checks foreign key integrity. How do you get that
right?

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

error with Dates in SQL Server
An application that run without flaw last week has been reported to
crash with an error that says that a conversion from char to datetime
has given a date outside range.
This very application runs OK today in production (fortunately :-),
and the difference in both SQL Servers is just that the one where the
exception has started to appear has Spanish conventions. I can''t give

eager loading and polymorphic associations
There is a dedicated section about eager loading in the docs. A
coworker discovered eager loading does not work in polymorphic
associations the hard way :-) so I''ve written a patch that documents it:
http://dev.rubyonrails.org/ticket/10610
There are at least a couple of tickets that implement something that
would change that though:

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?

support back button
There are a couple of links in the wiki about AJAX and the back

I have a page with AJAXified tables and normal links. When the user
modifies some table, follows a normal link, and presses the back
button, the shown tables are the original ones (modifications are OK
in backend). Is there some standard solution to this?

write attribute coming from where?
There are datatypes that need to be converted back and forth from a
string representation: they need to be parsed both coming from the
database, and coming from elsewhere like views.
Dates are an example, and I recently needed to implement a more
forgiving converter for decimal numbers. So we have here at least two
flows of execution, for example:
post.date = "22-jan-2007"
