ActiveRecord: mapping column names when using legacy schemata
I have an ActiveRecord question...
I have a legacy MySQL database with a weird naming convention - all
table and column names have a prefix ''_'' , which is annoying, and
some
of the column names are plain misnomers.
I would like to apply a pre-defined mapping between MySQL column names
and method names to be used in the Ruby class, without having the
underlying
column names

Thread_pool bug?
I have a previous question regarding long tasks and the thread_pool (sorry
for the dup, I didn''t see the first go through). To try and track things
down, I made a change based on a suggestion found in the archives. I moved
my import contacts worker to its own file and set the pool_size to 1.
class ImportContactsWorker < BackgrounDRb::MetaWorker

Lack of 'LEFT JOIN' in Oracle 8, any patch for theta style (+)
Dears,
Oracle 8 don''t support ANSI syntax with :
SELECT e.emp_id,
e.fname,
e.lname,
j.jobdesc
FROM employe e
LEFT JOIN jobs j ON e.job_id = j.job_id
but only
SELECT e.emp_id,
e.fname,
e.lname,
j.jobdesc
FROM employe e,
jobs j
WHERE j.job_id (+) = e.job_id
JOIN syntax came with 9i.

Strange problem
I use backgroundrb for many long tasks in my system, but I''m having issues

job = ImportJob.find(job_id)
job.process_job

JOIN conditions
Hi,
how can I get Rails to generate SQL queries with conditions in the JOIN clause?
What I would want is:
SELECT * FROM people p
LEFT OUTER JOIN jobs j (p.job_id = j.id AND j.salary > 9999999)
I tried
People.find(:all, :include => ''jobs'', :conditions => ''jobs.salary > 9999999'')
but that generates
SELECT * FROM people p
LEFT OUTER

Better rails way to join tables?
Hi,
I''ve figured out how to join tables using :joins, but is there a more
elegant way to do this using built-in rails methods?
Here is the code:
Hiringstep_Job.find(
:all,
:joins => ", hiringsteps",
:conditions => ["hiringstep_jobs.hiringstep_id = hiringsteps.id AND
job_id = ?", 1])
Thanks,
David

mySQL 5.0 upgrade - incompatible DateTime format?
I''ve upgraded to mySQL 5.0, and it''s gone pretty smoothly except that on
DateTime.now doesn''t seem to return a value that mySQL likes any more,
as seen in the following exception:
Incorrect datetime value: ''2005-11-20T15:33:12-0800'' for column ''logged_at'' at row 1: UPDATE notes SET `due_on` = ''2005-11-20'',

SPOOLSV and XP PRO
Hi All
I recently began having issues where there would be a runaway SMBD

CPU indefinitely.
IPTRAF reports around 600kbps constantly in and out from the subject
workstation, with nothing going on - on the workstation. This traffic
is parallel to the runaway SMBD process ... the traffic dies when the

Asterisk 1.8.20 AGI function SAY DATETIME does not play anything when mode in say.conf is changed to "new"
Hi
I am using following say.conf file. Its a default file, which comes with
Asterisk installation.
When I call SAY DATETIME AGI function, it simply returns without playing
date & time. Where as if I use mode=old setting, it works. Is this a bug
or mode=new is not implemented for SAY DATETIME AGI function?

A new QueueWorker class
Hello all,
I''ve come up w/ a worker class that manages queued jobs using a fixed
number of child workers. Well, that''s not quite true -- a new worker is
spawned for each job, but you set the total number that may exist at once.
There are three components:
1) queue_worker.rb: The singleton worker that manages the child workers.
You probably want to auto start this. Make sure you

module : cdr_sybase.so
If anyone is interested ... just in case! :-)... I have tried to write ,
based on the cdr_mysql.so module, an Sybase module.
To compile you can use something like that:
export SYBPLATFORM=linux
export SYBASE=/opt/sybase
cc -I$SYBASE/include -c -o cdr_sybase.o cdr_sybase.c
cc -shared -Xlinker -x -o cdr_sybase.so cdr_sybase.o -lsybdb -lm
