Generates username suggestions

UsernameSuggester

It generates username suggestions for users. It works with MySQL and any DB that supports “RLIKE”. If enough people request, I will add the support for not using RLIKE for those DB does not support it. (although it will be slower)

Usage

In your environment.rb, add:

config.gem 'username_suggester'

Assume you have an User model with attributes :username, :firstname, :lastname

class User < ActiveRecord::Base
  suggestions_for :username, :num_suggestions => 5,
    :first_name_attribute => :firstname, :last_name_attribute => lastname

  ...

end

And now you can call the suggestion function like the following:

user = User.new(:firstname => "Jerry", :lastname => "Luk")
user.username_suggestions

You can also filter the suggestions, let's say you want the username to contain at least 4 characters:

suggestions_for :username, :num_suggestions => 10,
  :validate => Proc.new { |username| username.length >= 4 }
