Uploadbox

Easy uploads for Rails application

Code Climate

Early Beta

This is still an early beta version and will change a lot until it reaches API stability. That said, it's already being used on production projects.

Installation

Make sure you have ImageMagick installed.

Add to Gemfile

gem 'uploadbox', '0.2.0'

Run generators

rails g uploadbox:image

Migrate database

rake db:migrate

Add jquery and uploadbox to application.js

//= require jquery
//= require jquery_ujs
//= require uploadbox

Add uploadbox to application.css

/*
 *= require uploadbox
 */

Create a development bucket on Amazon S3

Edit CORS config for the bucket

<CORSConfiguration>
  <CORSRule>
    <AllowedOrigin>http://localhost:3000</AllowedOrigin>
    <AllowedMethod>GET</AllowedMethod>
    <AllowedMethod>POST</AllowedMethod>
    <AllowedMethod>PUT</AllowedMethod>
    <AllowedHeader>*</AllowedHeader>
  </CORSRule>
</CORSConfiguration>

Get S3 Key and Secret from Amazon S3 Credentials and update your secrets.yml file.

development:
  s3_bucket: your-bucket-name
  s3_key: your-s3-key
  s3_secret: your-s3-secret

Usage

uploads_one

Add uploads_one to your model

class Post < ActiveRecord::Base
  uploads_one :picture, thumb: [100, 100], regular: [600, 300], placeholder: 'default.png'
end

If placeholder is set posts without uploads will render the placeholder. Empty @post.picture.thumb will render app/assets/images/thumb_default.png

Add field to form

<%= f.uploads_one :picture %>

You can pass a :preview option, so that the field will have the dimensions specified in the model.

<%= f.uploads_one :picture, preview: :thumb %>

Allow attribute on controller

def post_params
  params.require(:post).permit(:title, :body, :picture)
end

Show image

<%= img @post.picture.regular if @post.picture? %>

uploads_many

Add uploads_many to your model

class User < ActiveRecord::Base
  uploads_many :pictures, thumb: [100, 100], regular: [600, 600], placeholder: 'default.png'
end

Add field to form

<%= f.uploads_many :pictures %>

You can pass a :preview option, so that the field will have the dimensions specified in the model.

<%= f.uploads_one :pictures, preview: :thumb %>

Allow attributes on controller

def post_params
  params.require(:user).permit(..., pictures: [])
end

Show images

<% @user.pictures.each do |pic| %>
  <%= img pic.regular %>
<% end %>

Set background_processing to false if you're using Heroku

Go to config/initializers/uploadbox.rb, find the line where background_processing is being set and set it to false.

Uploadbox.background_processing  = false

Recreate versions

You might come to a situation where you want to retroactively change a version or add a new one. You can use the update_#{upload_name}_versions! method to recreate the versions from the base file. For a post with a picture:

Post.update_picture_versions!

Heroku

Create a production bucket on S3 (Don't use your development bucket)

<CORSConfiguration>
  <CORSRule>
    <AllowedOrigin>http://yourdomain.com</AllowedOrigin>
    <AllowedMethod>GET</AllowedMethod>
    <AllowedMethod>POST</AllowedMethod>
    <AllowedMethod>PUT</AllowedMethod>
    <AllowedHeader>*</AllowedHeader>
  </CORSRule>
</CORSConfiguration>

Set environment variables

heroku config:add \
HEROKU_API_KEY=ab12acvc12 \
HEROKU_APP=your-app-name \
S3_KEY=AAAA123BBBB \
S3_SECRET=abc123ABcEffgee122 \
S3_BUCKET=uploads-production

Update your secrets.yml file

production:
  s3_key:  <%= ENV["S3_KEY"] %>
  s3_secret: <%= ENV["S3_SECRET"] %>
  s3_bucket: <%= ENV["S3_BUCKET"] %>

Add Redis

heroku addons:add rediscloud

Upgrade from 0.1.x

If are upgrading from 0.1.x you will need to create a migration to add a column named original_file to the images table

rails g migration add_original_file_to_images original_file:string
rake db:migrate
