Unicode strings in TEMPLATES settings

[MikeVL]

My config file with unicode strings raise error TypeError: Item in ``from list'' not a string

# -*- coding: utf-8 -*-
from __future__ import absolute_import, unicode_literals

TEMPLATES = [
    {
        'BACKEND': 'django_jinja.backend.Jinja2',
        'NAME': 'jinja2',
        'APP_DIRS': True,
        'DIRS': [
            PROJECT_ROOT('templates')
        ],
        'OPTIONS': {
            'match_extension': '.jinja',
            'context_processors': [
                'django.contrib.auth.context_processors.auth',
                'django.contrib.messages.context_processors.messages',
                ...
            ],
            'extensions': [
                'jinja2.ext.do',
                'jinja2.ext.loopcontrols',
                'jinja2.ext.with_',
                'jinja2.ext.i18n',
                'jinja2.ext.autoescape',
                'django_jinja.builtins.extensions.CsrfExtension',
                'django_jinja.builtins.extensions.CacheExtension',
                'django_jinja.builtins.extensions.TimezoneExtension',
                'django_jinja.builtins.extensions.UrlsExtension',
                'django_jinja.builtins.extensions.StaticFilesExtension',
                'django_jinja.builtins.extensions.DjangoFiltersExtension',
                ...
            ]
        }
    },
]

But this config working fine:

# -*- coding: utf-8 -*-
from __future__ import absolute_import, unicode_literals

...

TEMPLATES = [
    {
        'BACKEND': 'django_jinja.backend.Jinja2',
        'NAME': 'jinja2',
        'APP_DIRS': True,
        'DIRS': [
            PROJECT_ROOT('templates')
        ],
        'OPTIONS': {
            'match_extension': '.jinja',
            'context_processors': [
                b'django.contrib.auth.context_processors.auth',
                b'django.contrib.messages.context_processors.messages',
                ...
            ],
            'extensions': [
                b'jinja2.ext.do',
                b'jinja2.ext.loopcontrols',
                b'jinja2.ext.with_',
                b'jinja2.ext.i18n',
                b'jinja2.ext.autoescape',
                b'django_jinja.builtins.extensions.CsrfExtension',
                b'django_jinja.builtins.extensions.CacheExtension',
                b'django_jinja.builtins.extensions.TimezoneExtension',
                b'django_jinja.builtins.extensions.UrlsExtension',
                b'django_jinja.builtins.extensions.StaticFilesExtension',
                b'django_jinja.builtins.extensions.DjangoFiltersExtension',
                ...
            ]
        }
    },
]

TypeError: Item in ``from list'' not a string

Seems not related to django-jinja, the error is happens on jinja2, the extensions list is passed directly to jinja environment constructor. :(

Maybe a solution can be convert to the bytestring the list of extensions before pass it to the jinja2 on python2...

[MikeVL]

May be add notes about this in docs ?

[wizpig64]

closing this as we no longer support python2.
