Comment:
Unlike the 404 page, Django deliberately hobbles the rendering of the 500
page. `request.user` which is provided by a piece of middleware is not
available. It is recommended that you do not interact with the database
during the rendering of a 500 as it is impossible to know why you're on
the page and what pieces of middleware have run.
If for example there is a 500 because the database is unavailable, a 500
page which loads the user from the database would also error during its
rendering - what do we do then? You could register a custom 500 handler
which tried to carefully render a page using the user if it could, and
fell back to a flat 500 page if not, but personally I would not advise it.
I'm going to close this ticket as won't fix because I think Django's way
of handling of the 500 page is correct - it should do its best to avoid
any possible errors.
