Description

This proposal introduces optional strict handling for template variables.

Currently, Django silently renders missing variables as empty strings.
This feature would allow enabling a strict mode where undefined variables
raise an exception instead.

The proposal includes:

  • A global strict template variable setting.
  • Optional per-variable override behavior.
  • Backward compatibility by keeping strict mode disabled by default.

Feedback is welcome before proceeding further.

This feature seems to be good, since it's hard to find the incorrect variable name if there aren't any exceptions.
Is it needed to add a screenshot when the context variable name is invalid to reproduce the issue?
