Hi:
I have the following classes and would like to create a left join so
that I can sort by the plant 'name' field
class Requisition(SQLObject):
class sqlmeta:
style = Style(longID=True)
idName = 'requisitionId'
plant = ForeignKey('Plant', dbName='plantId')
requisitionPeriod = ForeignKey('RequisitionPeriod',
dbName='requisitionPeriodId')
itemNumber = UnicodeCol(length=15)
itemName = UnicodeCol(length=50)
requestedBy = ForeignKey('User', dbName='requestedById')
dateRequested = DateCol()
quantity = IntCol()
uom = UnicodeCol(length=20)
quantityReceived = IntCol()
dateReceived = DateCol()
dateCanHold = DateCol()
dateNeeded = DateCol()
class Plant(SQLObject):
class sqlmeta:
style = Style(longID=True)
idName = 'plantId'
plantNumber = IntCol()
name = UnicodeCol(length=50, alternateID=True)
def __str__(self):
return '%s' % (self.name)
I've read a bunch of the docs on the LEFT JOIN stuff, but can't seem to
figure out how this should work. I also read where it said that a left
join should rarely be necessary if you do things with proper object
techniques. Is there another way I should be looking at this? What I'm
trying to do is get a list of requisitions sorted by plant name.
