Gravatar Rails Helper

gistfile1.rb

# returns the Gravatar for the given user.
  def gravatar_for(user)
    gravatar_id = Digest::MD5::hexdigest(user.email.downcase)
    gravatar_url = "http://gravatar.com/avatar/#{gravatar_id}"
    image_tag(gravatar_url, alt: user.name, class:"gravatar")
end


#  This is a small rails helper that returns a users gravatar image
#  image alt text defaults to user.name, but can easily be changed.
