the query result had nothing!! when i 'diff' the environment of server and mine, i got one thing difference. one is python 2.5.2 and the other is 2.5.1, but i have no idea about why!
the problem is 『__year』, i set a datetime field in a django model, and i can query it by year with suffix parameter __year like filter(date__year=datetime.date.today().year). and it's work for mine but not for remote server. so for the general case, i changed the code to two queries like below:
filter(date__gte=datetime.date(datetime.date.today().year, 1,1), date__lte=datetime.date(datetime.date.today().year, 12,31))
then i changed 5 files in my application. before svn commit, i use svn diff to see what i modified and found a error.
Can you see??

if i have no subversion, i will write a bug after a debug.
