As written in nameko's document, I run this example and it works:
from nameko.runners import ServiceRunner
from nameko.testing.utils import get_container
from nameko.rpc import rpc
class ServiceA:
name = "service_a"
class ServiceB:
name = "service_b"
# create a runner for ServiceA and ServiceB
runner = ServiceRunner(config={})
runner.add_service(ServiceA)
runner.add_service(ServiceB)
# ``get_container`` will return the container for a particular service
container_a = get_container(runner, ServiceA)
# start both services
runner.start()
print('runner start')
# stop both services
runner.stop()
It shows:
runner start
but when i add a rpc method in service_a, and add a AMQP_URI in config, it doesn't work, looks like it doesn't connected to RabbitMQ. What should i do?
class ServiceA:
name = "service_a"
#rpc
def hello_a(self):
return 'hello service_a.'
config = {
'AMQP_URI': 'amqp://guest:guest#localhost',
}
runner = ServiceRunner(config=config)
when i press Ctrl+C:

I suspect you are missing import eventlet; eventlet.monkey_patch() at the top of your file. Eventlet is mentioned in the documentation but I think it could be clearer, and possibly explicitly added to some of the examples.
Alternatively you could use the bundled service runner (which handles this for you) by making a module with just your service definitions and using nameko run from the command line like in the hello world example

I'm trying to clone this Django repo and run it on my local machine, but I've run into the classic function() takes 1 positional argument but 2 were given error.
After cloning the repo I created a virtual environment and installed all the dependencies,
But when I run
py manage.py migrate
I get the above-mentioned error.
What's confusing me is that the error is occurring in a python file automatically generated in the virtual environment and according to other questions on SO about this, the code seems correct.
Here's the trace

Ok. I choose not to delete this question as I believe it might help other people who have the same problems.
Basically venusian does not support zipped egg. So when you produce your egg for pyramid, do not do it as zip egg.

TypeError: not all arguments converted during string formatting
I have tried almost everything that i found in google. Even deleted .coverage file and all .pyc but it still shows the same error.Any Idea..?
This TypeError is because of mixing different formats.
Your error is inside formatLogRecords()
Instead of:
msg = msg % self.args
You should use format():
myMsg = "{} {} {} {} {}".format(param1, param2, param3, param4)
And even much better approach will be:
args = ['1', '2', '3', '4']
myMsg = (' '.join('{}'.format(k) for k in args))
Result:
>>> 1 2 3 4
That way your args can be with a flexible.
One thing to try is to run nose with no log capturing --nologcapture. Most likely you have a rogue logging somewhere at the import level, and it chokes nose before tests can run.
You can usually expose those bugs easily if you just run python task.py on your test files - the error will get thrown immediately.
If this still does not solve your problem, try running nose within python using nose.run() within your test __main__ function, and fire it off with python -m pdb task.py it will let you debug such errors, even if --pdb option in nose does not work.
