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)

Forked Update¶ ↑

Support for last digits of phone has been added for more combinations and suggestions It is working for me with following Ruby, Rails & DB

• Ruby - 2.5.1

• Rails - 5.2.0

• DB - Postgres

Usage¶ ↑

In your Gemfile, add:

gem 'username_suggester', git: 'https://github.com/md-farhan-memon/username_suggester', branch: 'master'

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

class User < ActiveRecord::Base
  suggestions_for :username,
                  num_suggestions: 5,
                  first_name_attribute: :firstname,
                  last_name_attribute: lastname,
                  phone_attribute: :mobile_no,
                  last_n_digits_of_phone: 4

  ...

end

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

user = User.new(firstname: 'Jerry', lastname: 'Luk', mobile_no: '0123456789')
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 { |username| username.length < 4 }
