This is basic html behavior, you don't get a key if no values are
selected. Therefore I assume TW is honoring this. you could either
a- pass in attrs to the function with sane defaults for example
@expose()
def reportsave(self, passed=False,printRep=False):
reportData = DBSession.query(Report).filter(Report.id==kw
['id']).one()
reportData.passed = passed
reportData.printRep = printRep
or
b- you could use dict.get
@expose()
def reportsave(self, **kw):
reportData = DBSession.query(Report).filter(Report.id==kw
['id']).one()
reportData.passed = kw.get('passed',False)
reportData.printRep = kw.get('printRep',True)
it really depends on your style.
