This a known problem with Joins - they cannot guess what ForeignKey
points to them. The user is expected to help.

Either name your ForeignKey to match the table it references:
class DataRow(SQLObject):
type = StringCol()
data = BLOBCol(length=2**24)
text = UnicodeCol()
processRow = ForeignKey('ProcessRow')
^^^^^^^^^^
class ProcessRow(SQLObject):
path = StringCol()
status = StringCol()
data = SingleJoin('DataRow')
r = ProcessRow(path='here',status='loading')
datar=DataRow(data=d,type='binary',text='',processRow=r)
^^^^^^^^^^
or name the column explicitly:
class DataRow(SQLObject):
type = StringCol()
data = BLOBCol(length=2**24)
text = UnicodeCol()
row = ForeignKey('ProcessRow', joinColumn='row_id')
^^^^^^^^^^^^^^^^^^^
class ProcessRow(SQLObject):
path = StringCol()
status = StringCol()
data = SingleJoin('DataRow')
r = ProcessRow(path='here',status='loading')
datar=DataRow(data=d,type='binary',text='',row=r)
