Using Django "sites" framework to handle subdomains?
I am developing a language-based web application using Django. I would like to separate content using language subdomains (similar to Wikipedia, Quora, and other multilingual websites). For instance, if my website were example.com, I would like to have en.example.com for the English version of my website, es.example.com for the Spanish version of my website, and so on and so forth. I came across different Django third-party libraries that could help with subdomains but I was considering using the "sites" framework from Django itself. However, its documentation is not very explicit about subdomains but rather just talks about "websites" and it's not clear whether the framework would be suitable for my purpose. So, my question is: is the Django "sites" framework a good option for handling subdomain in a fashion similar to the one described above? -

I tried a lot of things, my actual code: template2 = default_storage.open(grupo.email.correo.path, 'r') template = template2.read() template = unidecode(template) template = Template(template) html = template.render(Context({})) email = EmailMessage( subject, html, to=[to_email] ) email.content_subtype = 'HTML' email.send(fail_silently=False) The variable grupo.email.correo is the FileField. The result: As you see, in the right of each number should be €. I tried a lot of combinations, and I get a lot of other characters, but I can't get a good decoded string, anyone knows more about this? -
