Related to a previous post, I've simplified a model (running in
sqlite) to show the failure:
========= begin model.py =========
from turbogears.database import PackageHub
from sqlobject import *
hub = PackageHub('bupc')
__connection__ = hub
class owner(SQLObject):
my_pcinfo = ForeignKey('pcinfo',cascade=True)
FirstName = StringCol(length=20, varchar=True)
LastName = StringCol(length=30, varchar=True)
class pcinfo(SQLObject):
IPNbr = StringCol(length=15,varchar=True)
HostName = StringCol(length=40, varchar=True)
========= end model.py =========
When the ForeignKey() statement is present, trying to instantiate
owner(), I get the following error:
In [1]: o=model.owner()
...
/usr/lib/python2.5/site-packages/SQLObject-0.9.1-py2.5.egg/sqlobject/
converters.py in sqlrepr(obj, db)
234 if converter is None:
235 raise ValueError, "Unknown SQL builtin type: %s
for %s" % \
--> 236 (type(obj), repr(obj))
237 return converter(obj, db)
238 else:
<type 'exceptions.ValueError'>: Unknown SQL builtin type: <type
'classobj'> for <class sqlobject.sqlbuilder.NoDefault at 0x860ca1
This only happens when the ForeignKey statement is present. the error
stanza implies a 'converter'. Is there a converter class that the
model needs to see?
Thanks in advance for any hints.
