Silk fails on binary staticfiles content

[peterbe]

When I'm in production mode I'll let Nginx go straight to the filesystem on these things but when in debug mode I add this to my root urls.py:

if settings.DEBUG:
    urlpatterns += patterns('', url(r'^silk', include('silk.urls', namespace='silk')))
    urlpatterns += static(
        settings.MEDIA_URL,
        document_root=settings.MEDIA_ROOT
    )

Any request on something going through /cache/foo/bar.jpg will cause this traceback.

Oops, thought I'd fixed this!

That line of code currently tries to catch DjangoUnicodeDecodeError to deal with this issue, which is a descendent of UnicodeDecodeError.

I just pushed a fix for this. If you upgrade via pypi this issue should be resolved. Note changes to the models were made for 0.2 so you'll need to delete&sync/migrate.

Cheers

Was this issue solved in the end?

[peterbe]

I haven't tried out the new version yet. When I got stuck I just corrected my setup to serve these files directly from nginx locally.

Tested this pretty thoroughly so gonna close. Let me know if any further issues
