Comment (by pmocek):
I noticed what is likely a related problem. When the loaddata
command is used with the auto-generated manage.py, bad syntax
results in silent failure and a return code indicating success.
The built-in usage help shows that the fixture argument is
mandatory:
{{{
Usage: manage.py loaddata [options] fixture [fixture ...]
}}}
However, manage.py does not report an error when a fixture is not
specified:
{{{
$ ./manage.py loaddata
$ echo $?
0
}}}
Only when the verbosity level is increased from 0 to 2 is an error
reported, and the return code still indicates success:
{{{
$ ./manage.py loaddata --verbosity=1 ; echo $?
0
$ ./manage.py loaddata --verbosity=2 ; echo $?
No fixtures found.
0
}}}
Typically, silence implies successful completion. This problem is
particularly troublesome because the syntax for loaddata differs
significantly from that of dumpdata. It took

users/browse_frm/thread/d1a7de5a4efc58cb outside assistance]
for me -- new to Django but with a considerable amount of experience
using CLI utilities -- to determine why the following commands
completed with apparent success but left my database empty:
{{{
$ ./manage.py dumpdata >data.json
$ ./manage.ph flush
$ ./manage.py loaddata <data.json
}}}
