[Django]-Unicode-objects must be encoded before hashing

✅

user.email is a Unicode string, whereas the hash function can only operate on bytes. So you need to convert (i.e. encode) the string into a series of bytes, based on some Unicode character encoding.

Historically, email addresses were restricted to ASCII, but nowadays they can be UTF-8 as well. The gravatar documentation doesn’t mention an encoding, so it’s not clear if they support UTF-8 email addresses.

The simple answer is just to use email.lower().encode("utf-8"). Since ASCII is the same as UTF-8 throughout the ASCII range, this should work for all email addresses that Gravatar supports.

Are you using Python 3 right now? It because you need to encode your email as utf-8, example email.encode('utf-8'). here’is what I using for my currently project…

import hashlib
from django import template

try:
    # Python 3
    from urllib.parse import urlencode
except ImportError:
    # Python 2
    from urllib import urlencode

register = template.Library()

@register.filter
def gravatar(email, size="75"):
    """
    <img src='{{ request.user.email|gravatar:"75" }}'>
    """
    gravatar_url = "//www.gravatar.com/avatar/" + \
        hashlib.md5(email.encode('utf-8')).hexdigest() + "?"
    gravatar_url += urlencode({'d': 'retro', 's': str(size)})
    return gravatar_url

hope it usefull..
