Comment (by Alan Justino da Silva):
Replying to [comment:2 Sasha Romijn]:
> We might be talking about the two different mutually exclusive 500 views
in Django. As Tim's example includes the exception, that sounds like a
debug view.
Please correct me, but doing `str()` over an Exception returns only the
error name/details, not the full traceback. That is what I would expect as
a 500 on JSON, exactly the same as a 500 on HTML.
> What would you do with these values? When is it not enough to just look
at the 500 response code?
I expect JSON client callers to be able to parse the answers in JSON when
providing `Accept: application/json`, even if the call errors out.
> Also remember that Tim's example would not be acceptable in non-debug
mode (as default built-in Django view), because we don't want to provide
details on the exception in the output.
That is fair. What about providing only the same of HTML "Server Error
(500)" but in a JSON wrap instead of a HTML wrap?
> So, adding this to the code is simple, but I do not understand what
problem you are trying to solve. Until that is clarified, I'm closing as
wontfix.
The problem is about a client asking for `Accept: application/json` not
expecting to handle anything but JSON, and the 500 response being HTML
even for a request with `Accept: application/json`.
That said, would you reconsider the `wontfix` solution?
