ArrayAttributes

A Rails plugin to encapsulate common array attributes methods.

This gem can be used to avoid repeating the same methods in models when working with arrays.

This branch targets Ruby 2.4+ only

Add this line to your Gemfile:

gem 'array_attributes'

then run:

bundle install

class Book < ActiveRecord::Base
  string_array_attributes [:authors, :countries]
end

It assumes you are passing string attributes.

It also supports the following options:

• :reject_blank: whether the attribute should skip blank values
• :reject_if: condition to reject values

class Device < ActiveRecord::Base
  string_array_attributes [:ips], reject_blank: true, reject_if: ->(value) { value == '127.0.0.1' }
end

You can invoke attribute_raw to get the array values joined by commas.

book = Book.create(authors: ['John Doe', 'Jane Doe'])
book.authors_raw #=> "John Doe, Jane Doe"

You can invoke attribute_raw= to set the array value by entering the values split by commas.

book = Book.new
book.authors_raw="John Doe, Jane Doe"
book.save!
book.authors #=> ["John Doe", "Jane Doe"]
