has_gravatar

has_gravatar is intended to add easy access to gravatar URLs from Active Record models.

Installation

has_gravatar is distributed as a gem, which is how it should be used in your app.

First, include the gem in your Gemfile: gem "has_gravatar" And install it: bundle

After these two simple steps, has_gravatar is ready to be used on any Active Record model. In order to use it, call has_gravatar, passing one or more fields as argument. Example:

class User < ActiveRecord::Base
    has_gravatar :primary_email, :secondary_email, :email
end

Now, to get the Gravatar URL of a model, use:

user = User.first

# Returns http://gravatar.com/avatar/<hash>
user.email_gravatar

# Supports default images
user.email_gravatar default_avatar: 'http://my.domain.com/public/default_gravatar.png'

# And sizing
user.email_gravatar default_avatar: 'http://my.domain.com/public/default_gravatar.png', size: 128

# And HTTPS
user.email_gravatar default_avatar: 'http://my.domain.com/public/default_gravatar.png', size: 128, secure: true
