Notebook

Notebook is a Ruby file attachment library, that has easy integration with Rails and ActiveRecord.

Installation

Add this line to your application's Gemfile:

gem 'notebook'

And then execute:

$ bundle

Or install it yourself as:

$ gem install notebook

Rails Quickstart

Models

Rails 4

class User < ActiveRecord::Base
  notebook_attachment :profile_picture
end

Edit and New Views

<%= form_for @user, url: users_path, html: { multipart: true } do |form| %>
  <%= form.file_field :avatar %>
<% end %>

Controller

Rails 4

def create
  @user = User.create(user_params)
end

private
def user_params
  params.require(:user).permit(:avatar)
end

Show View

<%= image_tag @user.avatar.url %>

Deleting an Attachment

Set the attribute to nil and save.

@user.avatar = nil
@user.save

Configuration

To use a different storage location than /public, create a config/initializers/notebook.rb, and then set the following:

Notebook.public_directory = 'hi'

Plain Old Ruby

It's awesome you want to use plain Ruby without Rails with Notebook!

First off, you need to read in a file, and create a new Notebook::Attachment object, like so:

file = File.read("avatar.jpg")
attachment = Notebook::Attachment.new(file)

The last and final step is to just upload it!

attachment.upload

# get the url of the newly persisted file
attachment.url
