TypeError trying to run simple example from the documentation #85
Description
Hi there.
I was trying to run a simple example from the docs to see if stdnet was usefull for a project but I keep getting a TypeError: <lambda>() takes no arguments (1 given).
The example is this:
from stdnet import odm
class Fund(odm.StdModel):
name = odm.SymbolField(unique=True)
ccy = odm.SymbolField()
description = odm.CharField()
def __unicode__(self):
return self.name
if __name__ == "__main__":
models = odm.Router('redis://localhost:6379')
models.register(Fund)
models.register(Instrument)
models.register(Position)
with models.session().begin() as transaction:
transaction.add(models.fund(name='Markowitz', ccy='EUR'))
And the traceback is this:
(recsys)[/tmp]$ python fund.py
Traceback (most recent call last):
File "fund.py", line 42, in <module>

TypeError: <lambda>() takes no arguments (1 given)
I'm pretty sure it must be something dumb I did, but I couldn't find the problem. The version of stdnet is python-stdnet==0.8.2 installed via pip.

Python-stdnet 0.8.2
Redis 2.8.13
Python 2.7.9 (GCC 4.9.1 on linux2)
Ubuntu 14.10
Exactly the same output for me too

@mehmetb @rcalsaverini .The same happened to me. So the solution to solve the problems, You better to install the github master branch. you can fix the errors .
