最初由 Paul Kenjora 提交,非常感謝他, 並由 Carly Stambaugh 修改和改善。

import hashlib
import urllib
from django import template
from django.utils.safestring import mark_safe

register = template.Library()

# return only the URL of the gravatar
# TEMPLATE USE:  {{ email|gravatar_url:150 }}
def gravatar_url(email, size=40):
  default = ""
  return "" % (hashlib.md5(email.lower()).hexdigest(), urllib.urlencode({'d':default, 's':str(size)}))

# return an image tag with the gravatar
# TEMPLATE USE:  {{ email|gravatar:150 }}
def gravatar(email, size=40):
    url = gravatar_url(email, size)
    return mark_safe('' % (url, size, size))
