Simple DataStore Client
A simple Google DataStore client that exposes 3 functions on the DatastoreClient
class.
class DatastoreClient:
def __init__(self, namespace: str=None, **kwargs) -> None:
self.client = Client(namespace=namespace, **kwargs)
def set_key(
self,
entity_name: str,
key_name: str,
**properties: Any,
) -> None:
...
def get_key(
self,
entity_name: str,
key_name: str,
) -> Optional[Entity]:
...
def query_entity(
self,
entity_name: str,
*query_filters: Tuple[str, str, Any],
projection: List[str]=None,
limit: Optional[int]=None,
) -> Iterator:

Examples
namespace
Changing the You can set the namespace
for the client by passing it in to the constructor
from datastore_client.client import DatastoreClient
client = DatastoreClient(namespace='namespace_A')
The following will change the namespace for all subsequent function calls.
from datastore_client.client import DatastoreClient
client = DatastoreClient()
client.client.namespace = 'specific_namespace'
set_key
from datastore_client.client import DatastoreClient
client = DatastoreClient()
client.set_key(
entity_name=RECHARGE_NOTES_ENTITY,
key_name=note_key,
username=username,
reference=reference,
note=notes,
)
# This can also be used in batch mode
with client.batch_update():
client.set_key(...)
client.set_key(...)
# Both key updates will be done when the with block exits
get_key
from datastore_client.client import DatastoreClient
client = DatastoreClient()
client.get_key(LOGIN_ENTITY, username)
query_entity
from datastore_client.client import DatastoreClient
client = DatastoreClient()
product_list = list(client.query_entity(
PRODUCT_ENTITY,
('network', '=', network_name),
('product_type', '=', product_code),
('bundle_size', '=', denomination),
projection=['id'],
limit=1,
))
print(product_list[0]['id'])
