It takes 4 steps: configure your database.yml create an abstract class for connection create new models within a module interact the 2 databases 1. Configure your database.yml This is the same as you create production or development connection, just give it a specific name: other_database_connection: adapter: postgresql encoding: utf8 database: database_name username: user password: password host: localhost 2. ...

Huh, seems simple to do :p, but I' ve been seeking for a while to find the answer and dig into rails code to find a simple method to retrieve the controller of a given path (could be useful to build a navigation). There it is: ActionController :: Routing :: Routes . recognize_path ( path )[ :controller ]

Git is different from svn and create a private repository on a remote server too. No need of gitosis or git-daemon for this. I start from an existing project and a server I already access to with ssh key. First, initialize git in your project: git init git add . git commit -m 'initial import' Then create a git copy of your project into a git archive my_project_folder.git . git clone --bare my_project_folder my_project_folder.git Copy this archive to your remote ...

from help on irc#merb I had recurrent issue about inherit a model class from another one in Merb, using ActiveRecord or DataMapper. As it' s magicly' done on Rails I though the same way in Merb, but the last one load model class in alpha order. then what you have to do is to load the first class with a require: in your first file: class Page ActiveRecord :: Base end then in second add the require: require ' page ...

If like me you have an error after installing scrubyt 0.3.4 (in console and launching mongrel): can't activate RubyInline (= 3.6.3), already activated RubyInline-3.6.4] I spent a lot of time to find the solution, and so easy solution anyway could be useful for people googling about this. You just need to unsinstall the lastest installed version of RubyInline: sudo gem uninstall RubyInline -v 3.6.4 Everything should be fine with this, even Scrubyt requiring version 3.6.3.

This the second part for a summary about solutions to help better computing of your rails app ( 1st part ). Application To help your application to focus on replying fast to user, you can use a distributed queueing to give the job to other processes: Daemons Backgroundrb And second thing, you can cache things you don' t need to compute for each request, this can incredibly increase the response of your server, but need to modify your code and ...

One of the most interesting topic in the RailsConf was Scaling your Rails app . There are 2 ways of doing it: adapt your code adapt your servers But the second one will not help to make your code faster. It will just help to give maximum resources to compute it right. Summaries from the conference ( sorry for the so few litterature it will be only a summarize ): Some theories These theories are for big websites with millions ...

Nginx is a small' efficient http, load balancer server. Very popular in Rails community, it' s a good front end for mongrel clusters. It' s seems to be a good replacement for apache, at least for the memory usage (on my test: 1 process use 1.3M against the more than 9M taken by 1 apache process). Benchmark on one single server are quite similar. The process has been tested on debian 4.0r1 and should work on Ubuntu. Installation apt-get install ...

Following the conference, and some information about scaling Rails application, I decided to investigate about it and write a post on it. First, I tried to install FreeBSD as recommended for small configuration Well, I still don' t get it, I' m not fan of this installation and stop trying to understand, instead I installed a Debian 4.0R1, not so bad and closer to what I know :) Secondly, I want to try Nginx. First, need to find the good ...

For my training on Radiant I did a small extension to manage config parameters, usually accessible with the console or sql. installation: svn co http://www.rubynaut.net/svn/radiant/extensions/config_editor/ config_editor Done. I liked: the api to add your admin controls an asbtract model controller to help in managing your model' s CRUD with only few lines. the good practises you can get from the Radiant code :) Creating an extension with Radiant is so easy! I guess this system will become very popular, and ...
