Defined in:

lib/google/cloud/firestore/v1beta1/firestore_client.rb

Overview

The Cloud Firestore service.

This service exposes several types of comparable timestamps:

• +create_time+ - The time at which a document was created. Changes only when a document is deleted, then re-created. Increases in a strict monotonic fashion.
• +update_time+ - The time at which a document was last updated. Changes every time a document is modified. Does not change when a write results in no modifications. Increases in a strict monotonic fashion.
• +read_time+ - The time at which a particular state was observed. Used to denote a consistent snapshot of the database or the time at which a Document was observed to not exist.
• +commit_time+ - The time at which the writes in a transaction were committed. Any read with an equal or greater +read_time+ is guaranteed to see the effects of the transaction.

Constructor Details

#initialize(credentials: nil, scopes: ALL_SCOPES, client_config: {}, timeout: DEFAULT_TIMEOUT, metadata: nil, exception_transformer: nil, lib_name: nil, lib_version: "") ⇒ FirestoreClient

Returns a new instance of FirestoreClient

Parameters:

• credentials (Google::Auth::Credentials, String, Hash, GRPC::Core::Channel, GRPC::Core::ChannelCredentials, Proc) —

  Provides the means for authenticating requests made by the client. This parameter can be many types. A Google::Auth::Credentials uses a the properties of its represented keyfile for authenticating requests made by this client. A String will be treated as the path to the keyfile to be used for the construction of credentials for this client. A Hash will be treated as the contents of a keyfile to be used for the construction of credentials for this client. A GRPC::Core::Channel will be used to make calls through. A GRPC::Core::ChannelCredentials for the setting up the RPC client. The channel credentials should already be composed with a GRPC::Core::CallCredentials object. A Proc will be used as an updater_proc for the Grpc channel. The proc transforms the metadata for requests, generally, to give OAuth credentials.

• scopes (Array<String>) —

  The OAuth scopes for this service. This parameter is ignored if an updater_proc is supplied.

• client_config (Hash) —

  A Hash for call options for each method. See Google::Gax#construct_settings for the structure of this data. Falls back to the default config if not specified or the specified config is missing data points.

• timeout (Numeric) —

  The default timeout, in seconds, for calls made through this client.

• metadata (Hash) —

  Default metadata to be sent with each request. This can be overridden on a per call basis.

• exception_transformer (Proc) —

  An optional proc that intercepts any exceptions raised during an API call to inject custom error handling.

#run_query(parent, structured_query: nil, transaction: nil, new_transaction: nil, read_time: nil, options: nil) ⇒ Enumerable<Google::Firestore::V1beta1::RunQueryResponse>

Runs a query.

Examples:

require "google/cloud/firestore/v1beta1"

firestore_client = Google::Cloud::Firestore::V1beta1.new
formatted_parent = Google::Cloud::Firestore::V1beta1::FirestoreClient.any_path_path("[PROJECT]", "[DATABASE]", "[DOCUMENT]", "[ANY_PATH]")
firestore_client.run_query(formatted_parent).each do |element|
  # Process element.
end

Parameters:

• parent (String) —

  The parent resource name. In the format: +projects/project_id/databases/database_id/documents+ or +projects/project_id/databases/database_id/documents/document_path+. For example: +projects/my-project/databases/my-database/documents+ or +projects/my-project/databases/my-database/documents/chatrooms/my-chatroom+

• structured_query (Google::Firestore::V1beta1::StructuredQuery | Hash) —

  A structured query. A hash of the same form as Google::Firestore::V1beta1::StructuredQuery can also be provided.

• transaction (String) —

  Reads documents in a transaction.

• new_transaction (Google::Firestore::V1beta1::TransactionOptions | Hash) —

  Starts a new transaction and reads the documents. Defaults to a read-only transaction. The new transaction ID will be returned as the first response in the stream. A hash of the same form as Google::Firestore::V1beta1::TransactionOptions can also be provided.

• read_time (Google::Protobuf::Timestamp | Hash) —

  Reads documents as they were at the given time. This may not be older than 60 seconds. A hash of the same form as Google::Protobuf::Timestamp can also be provided.

• options (Google::Gax::CallOptions) —

  Overrides the default settings for this call, e.g, timeout, retries, etc.

Returns:

• (Enumerable<Google::Firestore::V1beta1::RunQueryResponse>) —

  An enumerable of Google::Firestore::V1beta1::RunQueryResponse instances.

Raises:

• (Google::Gax::GaxError) —

  if the RPC is aborted.

#update_document(document, update_mask, mask: nil, current_document: nil, options: nil) {|result, operation| ... } ⇒ Google::Firestore::V1beta1::Document

Updates or inserts a document.

Examples:

require "google/cloud/firestore/v1beta1"

firestore_client = Google::Cloud::Firestore::V1beta1.new

# TODO: Initialize +document+:
document = {}

# TODO: Initialize +update_mask+:
update_mask = {}
response = firestore_client.update_document(document, update_mask)

Parameters:

• document (Google::Firestore::V1beta1::Document | Hash) —

  The updated document. Creates the document if it does not already exist. A hash of the same form as Google::Firestore::V1beta1::Document can also be provided.

• update_mask (Google::Firestore::V1beta1::DocumentMask | Hash) —

  The fields to update. None of the field paths in the mask may contain a reserved name.

  If the document exists on the server and has fields not referenced in the mask, they are left unchanged. Fields referenced in the mask, but not present in the input document, are deleted from the document on the server. A hash of the same form as Google::Firestore::V1beta1::DocumentMask can also be provided.

• mask (Google::Firestore::V1beta1::DocumentMask | Hash) —

  The fields to return. If not set, returns all fields.

  If the document has a field that is not present in this mask, that field will not be returned in the response. A hash of the same form as Google::Firestore::V1beta1::DocumentMask can also be provided.

• current_document (Google::Firestore::V1beta1::Precondition | Hash) —

  An optional precondition on the document. The request will fail if this is set and not met by the target document. A hash of the same form as Google::Firestore::V1beta1::Precondition can also be provided.

• options (Google::Gax::CallOptions) —

  Overrides the default settings for this call, e.g, timeout, retries, etc.

Yields:

• (result, operation) —

  Access the result along with the RPC operation

Yield Parameters:

• result (Google::Firestore::V1beta1::Document)
• operation (GRPC::ActiveCall::Operation)

Returns:

• (Google::Firestore::V1beta1::Document)

Raises:

• (Google::Gax::GaxError) —

  if the RPC is aborted.

#write(reqs, options: nil) ⇒ Enumerable<Google::Firestore::V1beta1::WriteResponse>

Note:

EXPERIMENTAL: Streaming requests are still undergoing review. This method interface might change in the future.

Streams batches of document updates and deletes, in order.

Examples:

require "google/cloud/firestore/v1beta1"

firestore_client = Google::Cloud::Firestore::V1beta1.new
formatted_database = Google::Cloud::Firestore::V1beta1::FirestoreClient.database_root_path("[PROJECT]", "[DATABASE]")
request = { database: formatted_database }
requests = [request]
firestore_client.write(requests).each do |element|
  # Process element.
end

Parameters:

• reqs (Enumerable<Google::Firestore::V1beta1::WriteRequest>) —

  The input requests.

• options (Google::Gax::CallOptions) —

  Overrides the default settings for this call, e.g, timeout, retries, etc.

Returns:

• (Enumerable<Google::Firestore::V1beta1::WriteResponse>) —

  An enumerable of Google::Firestore::V1beta1::WriteResponse instances.

Raises:

• (Google::Gax::GaxError) —

  if the RPC is aborted.
