A super basic gem to check if a string has profanites.
Add this line to your application's Gemfile:
gem 'naughty_words'And then execute:
$ bundle install
Or install it yourself as:
$ gem install naughty_words
Check if a string includes a profanity
The check method takes in a string: argument and will return a boolean.
NaughtyWords.check(string: "ass")
=> true
NaughtyWords.check(string: "hello world")
=> false
NaughtyWords.check(string: "hello asshole")
=> trueFilter out words
The filter method takes a string: argument and an optional replacement: argument.
# passing a string with no profanity will return the string
NaughtyWords.filter(string: "hello world")
=> "hello world"
# passing a string with profanities will return the string with the profanity filtered out
NaughtyWords.filter(string: "hello asshole")
=> "hello *******"
# you can filter out consecutive naughty words
NaughtyWords.filter(string: "shitshitshityeah")
=> "************yeah"
# you can use in your own filter character by passing it in as an argument ("*" is by default)
NaughtyWords.filter(string: "hello asshole", replacement: "!")
=> "hello !!!!!!!"We can use a custom validator in our User model to make sure a user cannot sign up with a username containing profanities in tandem with our normal validates methods.
# app/models/user.rb
validates :username, uniqueness: true, presence: true # basic username validation
validate :username_profanity_check # our custom validator
...
def username_profanity_check
errors.add(:username, "contains profanity") if NaughtyWords.check(string: username)
