Library for creating data services
CsvDataService Example:
class Dummy:
def __init__(self, a, b, c):
self.a = a
self.b = b
self.c = c
def __str__(self):
return f"a: {self.a}, b: {self.b}, c: {self.c}"
def __repr__(self):
return self.__str__()
class CsvDataService_Dummy(ICsvDataService):
def __init__(self, data_file_path: str):
ICsvDataService.__init__(self, data_file_path)
def translate_from_data_rows(self, df: pd.DataFrame) -> List[T]:
ret_dummies = []
for i, row in df.iterrows():
new_dummy = Dummy(
a=row['a'],
b=row['b'],
c=row['c']
)
ret_dummies.append(new_dummy)
return ret_dummies
After Establishing the data service, data can be stored or retrieved as follows:
dummies = []
for ii in range(0, 5):
dummies.append(Dummy(ii, 2, 3))
data_service.add_or_update(obj_identifier='a', objs=dummies)
stored = data_service.retrieve_data(obj_identifier='a')
