Firestore in Datastore mode V1 API - Class Google::Cloud::Datastore::V1::Key (v1.2.0)

Reference documentation and code samples for the Firestore in Datastore mode V1 API class Google::Cloud::Datastore::V1::Key.

A unique identifier for an entity. If a key's partition ID or any of its path kinds or names are reserved/read-only, the key is reserved/read-only. A reserved/read-only key is forbidden in certain documented contexts.

Methods

#partition_id

def partition_id() -> ::Google::Cloud::Datastore::V1::PartitionId
Returns

#partition_id=

def partition_id=(value) -> ::Google::Cloud::Datastore::V1::PartitionId
Parameter
Returns

#path

def path() -> ::Array<::Google::Cloud::Datastore::V1::Key::PathElement>
Returns
  • (::Array<::Google::Cloud::Datastore::V1::Key::PathElement>) — The entity path. An entity path consists of one or more elements composed of a kind and a string or numerical identifier, which identify entities. The first element identifies a root entity, the second element identifies a child of the root entity, the third element identifies a child of the second entity, and so forth. The entities identified by all prefixes of the path are called the element's ancestors.

    An entity path is always fully complete: all of the entity's ancestors are required to be in the path along with the entity identifier itself. The only exception is that in some documented cases, the identifier in the last path element (for the entity) itself may be omitted. For example, the last path element of the key of Mutation.insert may have no identifier.

    A path can never be empty, and a path can have at most 100 elements.
