instance variables in templates
Hey all,
Well... hmm... feeling pretty stupid here...
For some reason my controller instance variables are not displaying
in my templates. I''ve boiled it down to this test case.
class Rss::FilmController < ApplicationController
def display
@time = Time.now
end
end
and the template:
<html>
<head>

ActiveRecord 1.13.2 -> 1.14.0 breaks Postgres connectivity
To Whom It May Concern:
I have an ActiveRecord-based application (non-Rails). Life was grand
until I upgraded ActiveRecord yesterday, after which point I was getting
TONNES of these errors from my app and in PostgreSQL''s logs:
FATAL: terminating connection due to administrator command
According to Google searching, this happens when an external process
sends PostgreSQL SIGINT or

Rails 1.1: not-null constraint violations
Since upgrading to Rails 1.1, I now get these errors:
PGError: ERROR: null value in column "added" violates not-null
constraint
: INSERT INTO authors ("added", ...) VALUES(NULL, ...)
The ''added'' column has a default of current_timestamp, and this used to
work fine with Rails 1.0. Are we supposed to put default values in

Default Date storage 0000-00-00?
So I have a database of orders more or less.(it is currently in the
process of being upgraded to mysql with a rails fronted, from OLD
Paradox database) On one page I made a ''create new order'' system. This
allows me to put in the due date and other info. However I wanted to put
in the default value of ''0000-00-00'' for the shipped date, as it hasn''t

OO model style: inheritance
Hi everybody
I am totally new to rails and I am trying to start a
tiny project to get familiar with rails. But I already
got my first problem and I would be happy if somebody
could point me in the best and cleanest direction.
I am trying to develop a small gallery app. Since I
would like to add more features in future I am trying
to design a clean OO architecture of my models:

rake migrate ignores '':null => false'' on mysql
I wanted to add a login string column to an existing table
=> I created a migration :
...
def self.up
add_column "members", "login" , :string, :null => false
end
...
remark: it shouldn''t work, as the table is not empty (=> ''login'' would
be null in the existing rows.)
problem:
rake migrate didn''t complain

One model won''t work like the others, generating weird error
I''ve been banging my head against this for quite some time and can''t
figure out what is going on. I''m doing up a web site based on Typo and
adding in some custom controllers. I''m running Typo from trunk, so it''s
using the version of rails in vendor/rails. Everything is going
smoothly...until now.
I have one model that JUST. WON''T. WORK.

bug in postgresql ''now'' time handling??
line 212 of postgresql_adapter.rb is
return Time.now.to_s if value =~ /^\(''now''::text\)::(date|timestamp)/
i don''t think this will work. in postgresql the field ''now'' is pinned to the
SAME TIME for the duration of a transaction. eg. if you do
begin transaction;
insert into t values(42, ''now'');

Form helpers don''t work with facade columns?
Hello all,
I''ve been trying to use a facade column but I notice that the form
helpers don''t seem to respect the facade.
In the following example I''m trying to story the prices as Integer
values but present them to the user as decimals.

def price=(new_price)

ActiveRecord, Mysql, NULL columns and uniqueness
Hi all.
Mysql allows to set multiple NULLs on columns with unique constraint,
it''s normal SQL. Well, but when I try to submit some form, all
unspecified values will be consodered as '''' (empty string) and
(Mysql::Error: Duplicate entry occurs (((. How I can teach ActiveRecord
to consider empty fields as NULL?

why I don''t like to use some 3rd party plugins
I''m not a professional developer in the sense that I''ve had any formal
training or experience. I taught myself programming two years ago and have
since moved to ruby and shortly after to rails - even now, i only develop as
a hobby. This means that a lot of developer best practises are foreign or
unknown to me, that''s why I love rails so much. You learn so much just

Realtime + MYSQL
I'm having a few issues with the MySQL realtime configuration in
CVS-HEAD. I tested it initially with realtime extensions (realtime_ext

and that works fine, So I though I'd go back and test a static

Simple range question
I have a model with a datetime field called start_date. I''d like to do
a find on the model so that it returns only records with the start_date
equal to the current day.
Something like this:

:conditions => //?? start_date equal to today''s date

"server" config option (and cmd-line option) don''t do anything for puppetd?
Hi guys,
Unlike what it says in the documentation and the --help output, I
can''t seem to get puppetd to use the --server setting. The only way I
can get puppetd to work is to include a ''puppet'' alias to the ip of
the machine I''m running puppetmasterd on in my hosts file.
The strange thing though, is that the logs of my puppetmaster show
that it *is* getting

Migrations - add_column :default=>true, :null=>false

Error: ERROR: column "notify_on_create" contains null values

Why doesn''t Rails set the new column to true, as it''s supposed to
default to? I tried :default=>1 as well (same
