Use sequel as a replacement for activerecord with rails 3
Branch: master



This gem provides the railtie that allows sequel to hook into rails 3.x and thus behave like a rails framework component. Just like activerecord does in rails, sequel_rails3 uses the railtie API to hook into rails. The two are actually hooked into rails almost identically.

The code for this gem was inspired by sequel-rails and activerecord of rails.


Simply install it as any other gem:

gem install sequel_rails3

Or when using bundler, add it got your Gemfile:

gem sequel_rails3

Quick Start

In every rails project edit config/application.rb file as this.

Comment out (or remove) this line:

require 'rails/all'

Insert these lines:

require "action_controller/railtie"
require "action_mailer/railtie"
require "sequel_rails3/railtie"

If you'd like to contribute a feature or bugfix: Thanks! To make sure your fix/feature has a high chance of being included, please read the following guidelines:

  1. Fork the project.

  2. Make your feature addition or bug fix.

  3. Add tests for it. This is important so we don’t break anything in a future version unintentionally.

  4. Commit, do not mess with rakefile, version, or history. (if you want to have your own version, that is fine but bump version in a commit by itself I can ignore when I pull)

  5. Send me a pull request. Bonus points for topic branches.

Something went wrong with that request. Please try again.
