active_admin_multi_upload

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 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 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 %>
