I have the following object model:
class Data(Model):
__keyspace__ = 'varilog'
__table_name__ = 'md_data'
id = columns.TimeUUID(partition_key=True, primary_key=True, required=True)
device = columns.Text(primary_key=True, required=True)
property = columns.Text(primary_key=True, required=True)
field = columns.Text(primary_key=True, required=True)
cyclestamp = columns.DateTime(static=True)
type = columns.Text(discriminator_column=True)
#text_value = columns.Text() # Will work
#value = columns.Text(db_field='text_value') # Will work but...
class DataText(Data):
__discriminator_value__ = 'str'
value = columns.Text(db_field='text_value') # Always None
#text_value = columns.Text() # Ok also
When I query an object, depending on the value of the type column, the correct object is returned (DataText in this example), however it's value is None while if I uncomment text_value I'll have the correct value.
It looks like db_field is not supported in a child class. Is this a bug?
