Gem Version Build

ActiveStorage Validator

ActiveStorage blob validator.

Installation

Add this line to your application's Gemfile:

gem 'activestorage-validator'

And then execute:

$ bundle

Or install it yourself as:

$ gem install activestorage-validator

Usage

class User < ApplicationRecord
  has_one_attached :avatar
  has_many_attached :photos

  validates :avatar, presence: true, blob: { content_type: :image } # supported options: :image, :audio, :video, :text
  validates :photos, presence: true, blob: { content_type: ['image/png', 'image/jpg', 'image/jpeg'], size_range: 1..(5.megabytes) }
  # validates :photos, presence: true, blob: { content_type: %r{^image/}, size_range: 1..(5.megabytes) }
end

Note: For has_many_attached, size is validated on each file individually. In the code above, :photos validation allows any number of photos to be upload, each one being 5 MB or less in size.
