Short informative posts, to the point.
In the past I used to keep all files containing sensitive data (passwords, api keys and other secrets) out of my git repository. For example, I would add database.yml in the .gitignore file. Then I would put my database.yml on my production server in the « shared » folder. Finally I would ask capistrano to create a […]
TL;DR: Read the title 😉 I spent too many hours debugging a feature spec in an application. Turns out I was simply not paying attention to what I was doing! In a fixture file, I was setting a field the following way: some_date: I didn’t pay attention to the fact that “some_date” was a Date […]
It’s been a little while that I have decided to always extract my gem binaries into my rails application “bin” path. That way, I always execute binaries by specifying the relative path. For example “./bin/rails g model User”. At first I wasn’t sure about the idea. I was like: “Wait a minute! I will have […]
Hi (Oh my God… he just started his blog post with ‘Hi’), Did you know that as of Rails 3.1, you can have nested has_many :through clauses in your models?

Here is how we did it: module TheModule attr_reader :items def initialize(*args) @items = [] def @items.<<(item) super "You added the item #{item} […]
MongoDB is an opensource document-oriented database in the vein of CouchDB. It’s been a while since I wanted to try this kind of database on a Rails project. After reading this nice tutorial today I decided to take some time to create a sample Rails 3 app and put it on github. I chose to […]
A quick and easy tip today. It won’t impress the veteran ruby developer, but it will impress every ruby newcomers, guaranteed! Say I have a horse racing ruby application that allow people to know information about every competing horses. I have an input box that people can use to enter the name of a horse. […]
You want a RESTful Rails app with a backend administration? The worst thing to do in my opinion is to use the same controllers for the public and the admin side. At first, it might look wise to do this. I mean, if you have a “books” resource, it would be logical that all methods […]
What if you want to generate reasonably short alphanumeric user activation codes without having to store anything in a DB (so in this case generating random user codes won’t do) ? Why would someone need this? Think about an application where you want to print activation cards and sell them to your customers. The customer […]
