ActiveScaffoldSignaturePad

Integrates a signature pad into forms, enabling users to capture signatures directly within your application.

Description

ActiveScaffoldSignaturePad integrates a digital signature pad into ActiveScaffold forms, allowing users to sign directly within the interface. This feature is useful for applications requiring digital approvals, agreements, or user authentication via handwritten signatures.

###

Installation

Add the following line to your Gemfile:

gem 'active_scaffold_signaturepad'

Then run:

bundle install

Usage & Options

Enable the signature pad in your controller:

class AgreementsController < ApplicationController
  active_scaffold :agreement do |config|
    config.columns[:signature].form_ui << :signaturepad
    config.columns[:signature].options = {
      :width => 150, # canvas width, default 250
      :height => 55, # canvas height, default 100
      :line_colour => 'transparent' # colour for signature line on canvas, transparent for none
    }
  end
end

Available options: line_colour, line_width, line_margin, line_top, bg_colour, pen_colour, pen_width, pen_cap, error_message_draw.

See jquery.signaturepad doc for reference about options.

If error_message_draw is a symbol it will be translated (using as_ method, so it must be on active_scaffold namespace)

Save image

Signaturepad sends a JSON representation to signature. It can be converted to image on server, adding some code to model: https://gist.github.com/branch14/4258871
