ActiveAdminMultiUpload

### Support for multiple image upload for a nested resource in ActiveAdmin

_This gem was built to work with Carrierwave & ActiveAdmin, and is based on the excellent jquery-fileupload-system._

ActiveAdminMultiUpload is a version of jquery-fileupload-ui built to work with nested objects and ActiveAdmin 1.0. It supports all major features including file-previews and progress bars, and has been built so as to have the simplest implentation possible. It has been tested with Rails 4.0.2 and Ruby 2.1.0

Getting Started

Carrierwave

---

This gem relies on [Carrierwave](github.com/carrierwaveuploader/carrierwave) to work. If you are unfamiliar with Carrierwave then I recommend have a look through it before using this gem. You can also check out [This Railscast](railscasts.com/episodes/253-carrierwave-file-uploads) by Ryan Bates to help you get started.

Installation

---

Add the gem to your Gemfile

‘gem “active_admin_multi_upload”`

and then run ‘bundle install`

Setup

---

For the sake of simplification for all examples below I am going to use the sample data.

• ‘Picture` will be the model that has an uploader associated with its `:image` attribute

• ‘Gallery` has many `:pictures`

You can also assume the ‘@gallery` refers to the current gallery that we are creating/editing.

**Substitute these with your own models and associations**

### Allow the Params

In ‘/admin/gallery.rb` add `permit_params picture_ids: []`

### Add the uploader

Within your form render the ‘active_admin_multi_upload/upload_form`

<%= f.inputs "Pictures" do %>
  <%= render "active_admin_multi_upload/upload_form", :resource => @gallery, :association => "pictures", attribute: "image" %>
<% end %>
