Django management command cannot see arguments? -


since upgrading django 1.8, there's strange bug in django management command.

i run follows: 

python manage.py my_command $db_name $db_user $db_pass

and collect arguments follows:

class command(basecommand):  def handle(self, *args, **options):     print args     db_name = args[0]     db_user = args[1]     db_pass = args[2]     self.conn = psycopg2.connect(database=db_name, user=db_user,                                  password=db_pass)

previously worked fine, see error:

usage: manage.py my_command [-h] [--version] [-v {0,1,2,3}]                                              [--settings settings]                                              [--pythonpath pythonpath]                                              [--traceback] [--no-color] manage.py my_command: error: unrecognized arguments: test test test

it's not getting far print args statement.

if run without arguments, errors on args[0] line, unsurprisingly.

am using args wrong here? or else going on?

it's change in django 1.8. detailed here:

management commands accept positional arguments¶

if have written custom management command accepts positional arguments , didn’t specify args command variable, might error error: unrecognized arguments: ..., variable parsing based on argparse doesn’t implicitly accept positional arguments. can make command backwards compatible setting args class variable. however, if don’t have keep compatibility older django versions, it’s better implement new add_arguments() method described in writing custom django-admin commands.

c++ - Difference between pre and post decrement in recursive function argument -

i have following sample code used pre-decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(--c); cout << c << endl; return; } } this function give output input 4 : dp3 dp2 dp1 dp0 0 1 2 3 but when use post decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(c--); cout << c << endl; return; } } output goes in infinite loop dp4 can explain me in detail why happens ? this happens because function(c--) called same value of c , when finishes c decremented. recursively called, hence called same value no chance of return , hit stack overflow error. assume this, int x = 1, y = 0; y = x++ result y == 1 , x == 2. if y = ++x , bot x , y 2.
