It looks like you're trying to localize a string, which is not a datetime object and, thus, doesn't have a tzinfo property. You'll have to convert your string to a datetime before trying to localize it. On Wed, Jan 3, 2018 at 3:42 PM, Inter Nemo wrote: > *Django:* 2.0.1 > *Error: * > >> 'str' o

Re: Django storing byte string for image

I used this project once: http://django-db-file-storage.readthedocs.io/en/latest/ It seems it uses a TextField for the file bytes. I would expect django.contrib.postgres to implement a binary field, but it don't. I guess you can implement your own field type for bytea, psycopg maps bytes to byte

Hi, I haven't used allauth specifically, but you can always do things like this: 1. Override the default templates by including your templates first. That way you will only get the functionality that your templates add. See here : https://docs.djangoproject.com/en/2.0/howto/overriding-templates/
