goqr

QR codes for ruby/rails using goqr.me API

Installation

Add it to your Gemfile and run the bundle command:

gem 'goqr'

Getting started

In rails, you can generate a QR code just using the goqr helper method:

<%= image_tag goqr(data: 'Hi! goqr is awesome!', size: '128x128') %>

Available options

All available options are the specified by goqr API documentation.

Gotchas

• If you want to generate a QR code just for text or urls, use the data parameter normally:

<%= image_tag goqr(data: 'Just text') %>

<%= image_tag goqr(data: 'http://patriciomacadden.com.ar') %>

• If you want to generate a QR code for phone numbers, just prepend TEL: in the data parameter:

<%= image_tag goqr(data: 'TEL:+542211234567') %>

• If you want to generate a QR code for SMSs, just prepend SMSTO: in the data parameter, separating the phone number and the text by a ::

<%= image_tag goqr(data: 'SMSTO:+542211234567:Hi!') %>
