-------------------------------------+-------------------------------------
By default the Django admin list view logs multiple errors while working
normally. This is somewhat undesirable since errors and tracebacks do not
typically accompany correct and expected behaviour.
Simply silencing all 'debug' template errors is less than ideal since it
hides other possible errors we want to be informed about.
If the error were shorter, perhaps not including the traceback, that may
be enough to improve the situation.
Basically, I don't expect the well tested and maintained admin templates
to emit a wall of errors that is more reminiscent of the entire world
being on fire due to horribly buggy code I have written.
This is the same issue that is behind #26886, just in a different
template. If there is no way to solve these at the template code level,
its probably fair to close this ticket as a duplicate of a new ticket for
the underlying problem that needs solving to make this less of an issue.
This is the large amount of error text accompanying debug logging when
loading any admin list view.
