Allow for strict mode in templates

[Michael Hübner]

I was struggeling with a get query that just wouldn't throw any exceptions. Then I stubled about this:

https://code.djangoproject.com/ticket/11909

I'm so sorry about the rude request in there, but it would be really helpful to allow for a "strict mode" in templates where errors get thrown to help debug issues.

Django logs warnings for missing variables. I believe this logging was added since that ticket was closed.

I recently wrote a blog post with some techniques you can use to hook into this logging and turn those errors into exceptions: https://adamj.eu/tech/2022/03/30/how-to-make-django-error-for-undefined-template-variables/ . I hope that helps.
