Hello All,
Just started using SQLObject yesterday, so if I made a rookie mistake
please tell me. It appears SQLObject doesn't allow me to have the same
column name as my table name. Here is the MySQL table definition:
CREATE TABLE `sysname` (
`sysname_id` int(11) NOT NULL auto_increment,
`sysname` varchar(64) NOT NULL,
PRIMARY KEY (`sysname_id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8
And the corresponding SQLObject code:
class Sysname(SQLObject):
class sqlmeta:
fromDatabase = True
idName = "sysname_id"
def getSysnameID(cls):
sysname = platform.system()
for s in cls.selectBy(sysname=sysname):
return s.id
return cls(sysname=sysname).id
getSysnameID = classmethod(getSysnameID)
print Sysname.getSysnameID()
I get the following traceback from SQLObject:
Traceback (most recent call last):
File "knightly/machine.py", line 22, in ?
print Sysname.getSysnameID()
File "knightly/machine.py", line 16, in getSysnameID
for s in cls.selectBy(sysname=sysname):

x.name) for x in self.sourceClass.sqlmeta.columnList]

line 403, in _getattrFromForeignKey
ret = getattr(self, column.name)==getattr(self.soClass,
'_SO_class_'+column.foreignKey).q.id
TypeError: cannot concatenate 'str' and 'NoneType' objects
If I change the column's name `sysname` to `name` and change the code
accordingly everything works fine. Is this a feature or a bug?
Thanks,
Brian
