I searched about our problem but couldn't find anny solution.
I've installed mysqlconnector in a virtual environment. I also changed the connection string from the sqlalchemy scaffold in pyramidsthat uses sqllite to connect, to our connection string using mysqlconnector:
sqlalchemy.url = mysql+mysqlconnector://admin:admin@127.0.0.1:3306/tetten
We use this code to initialise our database.
class Page(Base):
""" The SQLAlchemy declarative model class for a Page object. """
__tablename__ = 'pages'
id = Column(Integer, primary_key=True)
name = Column(String(40, convert_unicode=True), unique=True)
data = Column(String(40, convert_unicode=True))
def __init__(self, name, data):
self.name = name
self.data = data
class RootFactory(object):
__acl__ = [ (Allow, Everyone, 'view'),
(Allow, 'group:editors', 'edit') ]
def __init__(self, request):
pass
The table 'pages' is created in the database and also gets filled with the right data. When I go to my browser I get the following error:
**builtins.TypeError**
TypeError: embedded NUL character
with this output:

Does anny1 have a solution for my problem?
edit:
I found this link in the bug section of python. Altough I don't think it's a bug, this might be related to my problem. Can't seem to figure it out how it works tough. http://bugs.python.org/issue13617
