Hi All,
Found a bug using the SQLObject trunk from svn with MySQLdb 1.2.1 (the
default on Ubuntu). Using the following table:
CREATE TABLE `cron` (
`cron_id` int(11) NOT NULL auto_increment,
`module` enum('Build','Doc','Test') NOT NULL,
`args` varchar(256) NOT NULL,
`time` time NOT NULL,
`days_of_week` set('0','1','2','3','4','5','6') NOT NULL,
PRIMARY KEY (`cron_id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8
Using the following SQLObject code:
class Cron(SQLObject):
class sqlmeta:
fromDatabase = True
idName = "cron_id"
print Cron.sqlmeta.columns
print Cron.get(1)
I get the following:
{'args': <SOStringCol args default=''>, 'daysOfWeek': <SOCol
daysOfWeek default=''>, 'cronID': <SOIntCol cronID default=None>,
'module': <SOCol module default=''>, 'time': <SOCol time default=''>}
Traceback (most recent call last):
File "cron.py", line 41, in <module>
print Cron.get(1)

TypeError: str() takes at most 1 argument (3 given)
Upgrading to MySQLdb 1.2.2 yields the following correct output:
{'args': <SOStringCol args default=''>, 'daysOfWeek': <SOCol
daysOfWeek default=''>, 'cronID': <SOIntCol cronID default=None>,
'module': <SOCol module default=''>, 'time': <SOCol time default=''>}
<Cron 1 cronID=1L module='Build' args='everything'
time='datetime.timedelt...)' daysOfWeek='0,1,2'>
I noticed there is other MySQLdb version specific stuff in
mysqlconnection.py so maybe this should be added?
Why do the ENUM, SET, and TIME field types get interpreted as SOCol's.
Why not EnumCol, SetCol, and TimeCol? I can still access the data in
them, but not as I first thought. SetCol returns a string that I have
to then parse into a python set. And TimeCol comes out as a
datetime.timedelta, this appears to be a resurfaced bug that was fixed
in 0.7.2:
"If the DB API driver returns timedelta instead of time (MySQLdb does
this) it is converted to time; but if the timedelta has days an exception
is raised."
Thanks,
Brian
