has_gravatar

has_gravatar is intended to add easy access to Gravatar URLs from ActiveRecord models.

Installation

Add the following line to your Gemfile, depending on your Rails version:

For Rails 5 and upward

gem 'has_gravatar', '~> 0.0.3b'

For Rails 4.2.6 and backwards

gem 'has_gravatar', '~> 0.0.2'

And install it:

$ bundle

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

class User < ApplicationRecord
	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
