Lately I had a typo in app name in INSTALLED_APPS. What I get from django when trying to run manage.py shell, test etc. was:
$ python manage.py shell Error: No module named name_with_typo
Like you see this message just suggest, that importing were wrong, because module is not accessible.
If my module name was really "name_with_typo" I would find it very fast, but my name was "model", so browsing sources to find the reason was a bit exhausting.
I start debugger and find that exception was catched here:
# django/core/management/base.py:205 """ # Switch to English, because django-admin.py creates database content # like permissions, and those shouldn't contain any translations. # But only do this if we can assume we have a working settings file, # because django.utils.translation requires settings. if self.can_import_settings: try: from django.utils import translation translation.activate('en-us') except ImportError, e: # If settings should be available, but aren't, # raise the error and quit. sys.stderr.write(self.style.ERROR(str('Error: %s\n' % e))) sys.exit(1)
Exception was raised during
As you see it's not much intuitive...
Why not to make error message more verbose?
It would save our time.
Such "error handling" is used in many places of Django.
