I am sure this is easier than I am making it, but I just want to add a
property to a class so that decimal representations get truncated at 3
decimal digits.
My class is this:
class Measures(Model):
__tablename__ = 'xcelera_measures'
id = Column(Numeric, primary_key=True)
studyidk = Column(Numeric, ForeignKey('xcel.studyidk'))
xceleragroup = relationship("Xcelera")
explainstring = Column(String(255))
mrn = Column(String(255))
value = Column(Numeric)
__mapper_args__ = {
"order_by": [mrn]
}
and 'value' is the property/attribute that I want to also have a truncated
version available in the class.
I tried adding this to the class value_new = column_property("%.3f" %
value())
but got an error that
value_new = column_property("%.3f" % value)
TypeError: float argument required, not Column
I also tried this as a hybrid_property, but I don't think I was using it
correctly.
All I want to do is have the truncated version of my attribute available in
my class.
Thanks!
