[sourcecode language='ruby']
class SecondConnection < ActiveRecord::Base

SecondConnection.establish_connection(
:adapter => “informix”,
:host => “localhost”,
:username => “hansnase”,
:password => “very_secret”,
:database => “ccdb@localhost”
)

self.abstract_class = true
end
[/sourcecode]

“self.abstract_class = true” makes the thing actually work. Otherwise Rails seems to cache the database connection and does not switch back if you access any other classes but SecondConnection.

Yeah!

Later: Not so Yeah…

I had to establish another call to
[sourcecode language='ruby']
ActiveRecord::Base.establish_connection
logger.info { “Establishing Base Connection” }
log_connections
[/sourcecode]

I assume it’s either an Informix problem or related to the old rails version I’m driving with.
Nevertheless: It works now.

Here are some snippets from:

1. ChrizDee
2. Craig Ambrose

And? What did I do:

I first enabled Postfix using 1). After this I have changed /etc/aliases:

[sourcecode language='ruby']

echo ‘rails_mailer: “|/usr/local/bin/mail_handler.rb”‘ >> /etc/aliases
chmod 755 /usr/local/bin/mail_handler.rb”‘ >> /etc/aliases
sudo newaliases
sudo postfix reload

[/sourcecode]

[sourcecode language='ruby']
#!/usr/bin/ruby
require ‘net/http’
require ‘uri’Net::HTTP.post_form URI.parse(‘http://localhost:3000/emails’), { “email” => STDIN.read }

[/sourcecode]

The script above will be triggered by every mail that will be sent to rails_mailer@localhost (resp. your hostname). It will put a post-request to localhost:3000/email including the email in the parameter “email”.

I have some XML code from that I need parts being put into a simple hash (see below).

The following small ruby snippet does exactly this.

Only thing that’s not working is the “inner_xml” part. I personally don’t need it but your mileage may vary and you may want to fix the issue (and give me a note)

[sourcecode language='ruby']
require ‘rubygems’
require ‘hpricot’
require ‘pp’

text = <

I found an interesting site on the Web: http://matthall.wordpress.com/2006/12/06/how-to-execute-a-rails-controller-action-via-cron/ 

Tweaking it a bit:
require '../config/environment'
require 'pp'
id = ARGV[0]
if id.nil?
raise <
USAGE: $0 RESELLER_ID
eof
end
app = ActionController::Integration::Session.new
app.get "/kunden/status_mail/#{id}"

This works fine from a Rails subdirectory and calls the same action like http://RAILSSITE/kunden/status_mail/ID

Git ist ein Versionskontrollsystem, ähnlich wie das bekannte CVS bzw. dessen Nachfolger “Subversion”.
Der große Vorteil von “git” ist die hervorragende Unterstützung von “Branches”, etwas was ich mit CVS/Subversion immer nur ziemlich rudimentär hinbekommen habe.

Hier nun die Installation auf einem älteren SuSE-System:

1) Sourcecode von http://git.or.cz
cd /usr/local/src
aktuell: wget http://kernel.org/pub/software/scm/git/git-1.5.4.4.tar.bz2

2) auspacken
tar xjvpf git-1.5*
cd git-1.5*
./configure
make
make install

It’s that simple

Allerdings: Wenn Ihr mit einem nicht lokalen Repository arbeitet _muss_ die gleiche Prozedur auch auf dem Rechner mit dem Repository stattfinden (also wget, tar, configure, make, make install)
Sonst gibt’s immer ein freundliches:

git clone ssh://user@HOSTNAME/fileserver/git/REPOSITORY
Initialized empty Git repository in /home/jrelease/REPOSITORY/.git/
bash: git-upload-pack: command not found
fatal: The remote end hung up unexpectedly
fetch-pack from ‘ssh://user@HOSTNAME/fileserver/git/REPOSITORY’ failed.
