TheBigUsernameBlacklist

This library lets you validate usernames against a blacklist. The blacklist data is based on the data from The-Big-Username-Blacklist and contains privilege, programming terms, section names, financial terms and actions.

Installation

Add this line to your application's Gemfile:

gem 'the_big_username_blacklist'

And then execute:

$ bundle

Or install it yourself as:

$ gem install the_big_username_blacklist

Usage

Validating a username is easy, if the word is in the blacklist, return False (validation failed), otherwise True. Example:

> require 'the_big_username_blacklist'
> TheBigUsernameBlacklist.valid? 'martin'
true
>  TheBigUsernameBlacklist.valid? 'root'
false

If you want to use it as instance method, it's easy. Example:

class YourClass
  include TheBigUsernameBlacklist
end

YourClass.new.username_valid?('martin')

You want to add optional blacklist, you can use configuration on rails initializer Example: config/initializers/the_big_username_blacklist.rb

TheBigUsernameBlacklist.configure do |config|
  config.optional_usernames = %w(james)
end

TheBigUsernameBlacklist.valid? 'james' # => false
