TypeError trying to run simple example from the documentation

[rcalsaverini]

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):

    self._parser = parser_class(socket_read_size=socket_read_size)
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.

[mehmetb]

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 .
