active_scaffold_camera

h1. Camera for ActiveScaffold

Currently, this plugin is compatible with ActiveScaffold >= 3.4 gem.

h2. Overview

This plugin adds a camera viewer to take a snapshot from camera on ActiveScaffold forms. It uses "SayCheese.js":https://github.com/leemachin/say-cheese

h2. Installation

You'll need at least ActiveScaffold 3.4 to use this

gem install active_scaffold_camera

h2. Usage

h4. Step 1

Set column to use :snapshot form_ui

h4. Step 2

Setup snapshot using options method on column

# app/controllers/visitors_controller.rb

class VisitorsController < ApplicationController
  active_scaffold :visitor do |config|
    config.columns[:signature].form_ui = :signaturepad
    config.columns[:signature].options = {:source => -1}
  end
end

Available options: video_not_supported, audio_not_supported, media_forbidden, source

Source can be set to use a specific source instead of displaying source selector. It must be the source index, and it can be negative index to start from end. If no device on that index, first device will be used.

If video_not_supported, audio_not_supported or media_forbidden are symbols they will be translated (using as_ method, so it must be on active_scaffold namespace). They have a default translation.

h4. Save image

Snapshot form_ui sends a data url, encoded on base64, of the image, so it should be saved on column of blob type.
