Right now
[https://code.djangoproject.com/browser/django/trunk/django/core/management/base.py#L208
BaseCommand.execute catches errors] and outputs quite useless portions of
them.
For example, I'm trying to move quite large (and, unfortunately,
underdocumented) project from server to server. I know that I need to
install a few components, but I do not precisely know which. So I just try
running "runserver" command and fixing any errors occuring.
But soon an error like this appears:
Error: No module named exceptions
Ok, how can this error message help me to learn what's the problem? In my
opinion, it can't.
But when I remove the try-catch from aforementioned method, I get a
helpful traceback:
{{{
Traceback (most recent call last):
File "manage.py", line 13, in <module>
execute_manager(settings)
[...]
File "/[...]/utils.py", line 2, in <module>
from sqlalchemy.exceptions import OperationalError
ImportError: No module named exceptions
}}}
Oh, now I see that I obviously have problems with sqlalchemy installation.
The source of the problem is pinned down and quickly fixed.
The question is: what's the reason of having this try-catch in the first
place, if it serves only to turn a helpful traceback into a useless 1-line
error message? In my opinion, it should be removed altogether.
