google.appengine.api.datastore_entities.GdKind

A base class for gd namespace kinds.

Inherits From: Entity, expected_type

google.appengine.api.datastore_entities.GdKind(
    kind, title, kind_properties, contact_properties=[]
)

This class contains common logic for all gd namespace kinds. For example, this class translates datastore (app id, kind, key) tuples to tag: URIs appropriate for use in tags.

kind String
title String
kind_properties List of strings
contact_properties List of string

Methods

FromPb

View source

@staticmethod
FromPb(
    pb,
    validate_reserved_properties=True,
    default_kind='<not specified>'
)

Static factory method. Returns the Entity representation of the given protocol buffer (datastore_pb.Entity).

Args
pb datastore_pb.Entity or str encoding of a datastore_pb.Entity
validate_reserved_properties deprecated
default_kind str, the kind to use if the pb has no key.

Returns
Entity the Entity representation of pb

ToPb

View source

ToPb()

Converts this Entity to its protocol buffer representation.

Returns
entity_pb2.Entity

ToXml

View source

ToXml()

Returns an XML representation of this entity, as a string.

app

View source

app()

Returns the name of the application that created this entity, a string or None if not set.

clear

clear()

D.clear() -> None. Remove all items from D.

copy

View source

copy()

The copy method is not supported.

entity_group

View source

entity_group()

Returns this entity's entity group as a Key.

Note that the returned Key will be incomplete if this is a a root entity and its key is incomplete.

fromkeys

fromkeys(
    value, /
)

Create a new dictionary with keys from iterable and values set to value.

get

get(
    key, default, /
)

Return the value for key if key is in the dictionary, else default.

is_projection

View source

is_projection()

Returns if this entity is a projection from full entity.

Projected entities:

  • may not contain all properties from the original entity;
  • only contain single values for lists;
  • may not contain values with the same type as the original entity.

is_saved

View source

is_saved()

Returns if this entity has been saved to the datastore.

items

items()

D.items() -> a set-like object providing a view on D's items

key

View source

key()

Returns this entity's primary key, a Key instance.

keys

keys()

D.keys() -> a set-like object providing a view on D's keys

kind

View source

kind()

Returns this entity's kind, a string.

namespace

View source

namespace()

Returns the namespace of this entity, a string or None.

parent

View source

parent()

Returns this entity's parent, as a Key. If this entity has no parent, returns None.

pop

pop()

D.pop(k[,d]) -> v, remove specified key and return the corresponding value.

If the key is not found, return the default if given; otherwise, raise a KeyError.

popitem

popitem()

Remove and return a (key, value) pair as a 2-tuple.

Pairs are returned in LIFO (last-in, first-out) order. Raises KeyError if the dict is empty.

set_unindexed_properties

View source

set_unindexed_properties(
    unindexed_properties
)

setdefault

View source

setdefault(
    name, value
)

If the property exists, returns its value. Otherwise sets it to value.

If the property name is the empty string or not a string, raises BadPropertyError. If the value is not a supported type, raises BadValueError.

unindexed_properties

View source

unindexed_properties()

Returns this entity's unindexed properties, as a frozenset of strings.

update

View source

update(
    other
)

Updates this entity's properties from the values in other.

If any property name is the empty string or not a string, raises BadPropertyError. If any value is not a supported type, raises BadValueError.

values

values()

D.values() -> an object providing a view on D's values

__contains__

__contains__(
    key, /
)

True if the dictionary has the specified key, else False.

__eq__

__eq__(
    value, /
)

Return self==value.

__ge__

__ge__(
    value, /
)

Return self>=value.

__getitem__

__getitem__()

x.getitem(y) <==> x[y]

__gt__

__gt__(
    value, /
)

Return self>value.

__iter__

__iter__()

Implement iter(self).

__le__

__le__(
    value, /
)

Return self<=value.

__len__

__len__()

Return len(self).

__lt__

__lt__(
    value, /
)

Return self<value.

__ne__

__ne__(
    value, /
)

Return self!=value.

__or__

__or__(
    value, /
)

Return self|value.

__ror__

__ror__(
    value, /

Return value|self.
