A simple way to append sanitizers to attributes to Rails 5+ applications.

AttributesSanitizer

A simple way to append sanitizers to attributes on Rails.

Usage

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))

Installation

Add this line to your application's Gemfile:

gem 'attributes_sanitizer'

And then execute:

$ bundle

Or install it yourself as:

$ gem install attributes_sanitizer

attributes_sanitizer's Issues

Use ActiveRecord type cast to ensure types before reading and writing attributes

In order to avoid problems with data types, we must ensure the column type before accessing the overriders methods.
