Gravity

Gravity is a simple Gravatar plugin for Rails. It allows you to easily get Gravatar images and profile informations.

Installation

Just add it to your Gemfile like this:

gem "gravity"

and you're ready to go.

In your model:

class User < ActiveRecord::Base
  has_gravatar
end

In your views:

<%= image_tag @user.gravatar_image %>
<%= @user.gravatar_profile['displayName'] %>

This works if you have an email field in your model. To use a different field for email, pass the field name to the :email option:

class User < ActiveRecord::Base
  has_gravatar :email => :email_address
end

You can also pass options to the ´gravatar_image´ and ´gravatar_profile´ methods:

<%= image_tag @user.gravatar_image :size => 40, :default => 'identicon' %>
<%= @user.gravatar_profile(:secure => true)['displayName'] %>

Here is a complete list of options:

Option	Description	Default	Values
secure	Use SSL to call gravatar.org	false	true/false
size	The size of the image	80	1..512
default	The avatar image used by default	none	"404", "mm", "identicon", "monsterid", "wavatar", "retro" or an absolute URL (this must start with "http").
rating	The lowest level of ratings you want to allow	G	G, PG, R or X
forcedefault	Force usage of the default image	false	true/false
