django-debug-toolbar fails with jinja2

It is happening for me too.

I decided to use Django Template Engine for Debug Toolbar and Admin templates, and use jinja for other templates. Here is my config:

TEMPLATES = [
    {
        "BACKEND": "django_jinja.backend.Jinja2",
        "APP_DIRS": True,
        "OPTIONS": {
            "match_extension": ".jinja.html",
            'context_processors': [
                # Insert your TEMPLATE_CONTEXT_PROCESSORS here or use this
                # list if you haven't customized them:
                'django.contrib.auth.context_processors.auth',
                'django.contrib.messages.context_processors.messages',
                'board.context_processors.global_settings',
                'django.core.context_processors.request',
            ],
        }
    },
    {
        'BACKEND': 'django.template.backends.django.DjangoTemplates',
        'DIRS': [
            # insert your TEMPLATE_DIRS here
        ],
        'APP_DIRS': True,
        'OPTIONS': {
            'context_processors': [
                # Insert your TEMPLATE_CONTEXT_PROCESSORS here or use this
                # list if you haven't customized them:
                'django.contrib.auth.context_processors.auth',
                'django.contrib.messages.context_processors.messages',
                'board.context_processors.global_settings',
                'django.core.context_processors.request',
            ],
        },
    },
]

But it would be great if django-debug-toolbar will support jinja

[aaugustin]

Actually this ticket isn't about supporting Jinja2 (with the built-in support) but about supporting django-jinja (a third-party project that predates the built-in support, with a different philosophy).

Hello, @aaugustin ! Exactly =)

Does this issue in django-jinja has anything to do with this problem ?

https://github.com/niwinz/django-jinja/issues/151

Thanks for any help !

[douglas]

Maybe this could be a possible solution:

https://github.com/django-debug-toolbar/django-debug-toolbar/pull/791

Also, some info about using Try/Except instead of hasattr, to check the existence of the attribute:

HTH =)

[niwinz]

This is now fixed in django-jinja 2.1.0, and this issue can be considered as fixed I guess.

[alexpetralia]

I'm using django-jinja 2.1.1. I installed django-debug-toolbar and added it to INSTALLED_APPS. I believe those are all the steps necessary to get the toolbar working (even with jinja2, as per niwinz's most recent comment)?

If so, I'm getting this error:

Error during template rendering

In template /home/alexpetralia/Projects/mbta_django/venv/local/lib/python2.7/site-packages/debug_toolbar/templates/debug_toolbar/base.html, error at line 1

9   {% else %}
10  <script src="{% static 'debug_toolbar/js/jquery_existing.js' %}"></script>
11  {% endif %}

For reference (although I don't think it should make a difference?), here are my TEMPLATE settings:

TEMPLATES = [
    {
        'BACKEND': 'django_jinja.backend.Jinja2',
        'DIRS': ['templates'],
        'APP_DIRS': True,
        'OPTIONS': {
            'match_extension': '.html',
            'app_dirname': 'templates',
            "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",
            ],
            "bytecode_cache": {
                "name": "default",
                "backend": "django_jinja.cache.BytecodeCache",
                "enabled": False,
            },
            "autoescape": True,
        },

    },     
]

[niwinz]

You have configured jinja2 backend for all html files, this means that jinja2 engines will be used for all html files, but django-debug-toolbar uses django template engine and jinja2 can't compile django templates... that causes your error.

It is highly recommended use different extensions (like .jinja) for files that uses jinja2 template engine.

[aaugustin]

Thanks @niwinz!

Since it doesn't appear that changes are required in the toolbar, I'm going to close this issue.

[alexpetralia]

Thank you so much! Sorry I misunderstood. I fixed my problem now thanks to your advice.
