500 status code debugging view shouldn't localize numeric tags IDs/line numbers

[Ramiro Morales]

Contributor Kronuz opened a pull request (​https://github.com/django/django/pull/451) with a proposed fix to the issue.

I've added tests here: ​https://github.com/django/django/pull/1437

One thing missing in the proposed fix was importing the l10n template tag library (the one that contains the unlocalize filter) and this stopped me from merging the PR right away.

Until now the template is pretty self-contained and lean, e.g. it doesn't import template tag libraries (I suspect to minimize the risk of triggering other problems when trying to show a helpful version of the server error exceptions.)

Should I ignore all this and simply commit the fix?

New strategy that is less invasive, IMHO: Specify use_l10n=False when constructing the Context for the debug view. PR updated.

I plan to commit this soon

In 6c12cd15e990b0ff5a5e85328f0a092f4bfe8080:

Unlocalize line numbers and ids in debug 500 view.

While using USE_L10N, line numbers and IDs were printed as comma (or
locale equivalent) separated values.

Thanks Kronuz for the report and intial patch.

Fixes #20861.
