HabtmGenerator

Installation

Add this line to your application's Gemfile:

gem 'habtm_generator'

And then execute:

$ bundle

Or install it yourself as:

$ gem install habtm_generator

Usage

rails generate habtm user post

This will generate a migration, for:

  • creating table "posts_users" with user_id, post_id, no primary key
  • index on both columns

And will copy the "has_and_belongs_to_many :model" into both models (near the top of the models)

This process is reversible (with rails destroy habtm model1 model2).

Potential Caveats

  • Namespaced models will not work
