Configure logger in client

Using standard logger in python https://docs.python.org/2/library/logging.html#logging.basicConfig

import logging
from rockettm import send_task

# 50 CRITICAL, 40 ERROR, 30 WARNING, 20 INFO, 10 DEBUG, 0 NOTSET
logging.basicConfig(level=20)
send_task("queue_name", "name_task", "Pepito")

Configure logger in server

in settings.py:

# filename (DEFAULT "rockettm.log")
# level (DEFAULT 30)
# 50 CRITICAL, 40 ERROR, 30 WARNING, 20 INFO, 10 DEBUG, 0 NOTSET
logger = {'filename': "rockettm.log",  # optional,
                                       # is not defined print in console
          'level': 10  # optional
         }

Send task

# send task
from rockettm import send_task

send_task("queue_name", "name_task", "arg1", ["arg2", "2"], {'args': 3}, ('arg', 4))

Declare new task

Warning! if there are 2 tasks registered with the same name, will run 2!

# task example
from rockettm import task


@task('name_task')
def function1(*args, **kwargs):
    return True

# max_time(timeout in seconds) example
@task('name_task2', max_time=10)
def long_call(*args, **kwargs):
    return True

settings.py example

# settings.py example
ip = "localhost"
port = 5672

logger = {'filename': "rockettm.log",  # optional,
                                       # is not defined print in console
          'level': 10  # optional
          }

# search @task in imports
imports = ['examples.test1',
           'examples.test2']

# support params
# name (mandatory), string
# concurrency (mandatory), int
# durable (optional), boolean
# max_time (in seconds) (optional), int
queues = [{'name': 'rocket1', 'durable': True, 'concurrency': 7},
          {'name': 'rocket2', 'concurrency': 1},
          {'name': 'rocket3', 'concurrency': 1, 'max_time': 10}]
