AttributesSanitizer

A simple way to append sanitizers to attributes on Rails.

class Product < ApplicationRecord
  sanitize_attribute :title, with: -> (value) {
    value.gsub(/[1-9]/, 'X')
  }

  sanitize_attributes :title, :description, with: [:downcase, :strip_tags]
end

It comes with pre-defined sanitizers:

• :stringify which perform a to_s into the value, to be sanitized as a string. Can be used before other sanitizer, that depends to the value be a string
• :downcase which downcases a given attribute string
• :upcase which upcases a given attribute string
• :strip_tags which removes any tags from the given string based on Rails sanitize helper.
• :strip_emojis which removes any emoji from the given string
• :strip_spaces which removes any white spaces from the beginning and end of given attribute

You might define your own sanitizers:

# config/initializers/attribute_sanitizers.rb

AttributesSanitizer.define_sanitizer :reverse do |value|
  value.to_s.reverse
end

It also comes with predefined bundles:

class Product < ApplicationRecord
  sanitize_attribute :title, with: -> (value) {
    value.gsub(/[1-9]/, 'X')
  }

  sanitize_attributes :title, :description, with: :no_tags_emojis_or_extra_spaces
  # same as: `with: %i(stringify strip_tags strip_emojis strip_spaces)
end

And, finally, you are able to define your own bundles:

# config/initializers/attribute_sanitizers.rb
AttributesSanitizer.define_bundle(:my_bundle, %i(downcase strip_spaces))

Add this line to your application's Gemfile:

gem 'attributes_sanitizer'

And then execute:

$ bundle

Or install it yourself as:

$ gem install attributes_sanitizer
