#27825: ORM Object constructor does not cast types of it's attributes when
called
by reference

---------------------------------------------+------------------------
My experience is that when using the `Constructor` (`ORM`) class by
references with Django `1.10.5`
There might be some inconsistencies in the data (i.e. the attributes of
the created object may get the type of the input data instead of the
casted type of the ORM object property)
Example:
`models`
{{{
class Payment(models.Model):
amount_cash = models.DecimalField()
}}}
`some_test.py` - `object.create`
{{{
Class SomeTestCase:
def generate_orm_obj(self, _constructor, base_data=None,
modifiers=None):
objs = []
if not base_data:
base_data = {'amount_case': 123.00}
for modifier in modifiers:
actual_data = deepcopy(base_data)
actual_data.update(modifier)
_obj = _constructor.objects.create(**actual_data)
print(type(_obj.amount_cash)) # Decimal
return objs
}}}
`some_test.py` - `Constructor()`
{{{
Class SomeTestCase:
def generate_orm_obj(self, _constructor, base_data=None,
modifiers=None):
objs = []
if not base_data:
base_data = {'amount_case': 123.00}
for modifier in modifiers:
actual_data = deepcopy(base_data)
actual_data.update(modifier)
_obj = _constructor(**actual_data)
print(type(_obj.amount_cash)) # Float
objs.append(_obj) return objs
}}}
