Methods

#end_at

def end_at() -> ::Google::Cloud::Firestore::V1::Cursor

Returns

• (::Google::Cloud::Firestore::V1::Cursor) — A end point for the query results.

#end_at=

def end_at=(value) -> ::Google::Cloud::Firestore::V1::Cursor

Parameter

• value (::Google::Cloud::Firestore::V1::Cursor) — A end point for the query results.

Returns

• (::Google::Cloud::Firestore::V1::Cursor) — A end point for the query results.

#from

def from() -> ::Array<::Google::Cloud::Firestore::V1::StructuredQuery::CollectionSelector>

Returns

• (::Array<::Google::Cloud::Firestore::V1::StructuredQuery::CollectionSelector>) — The collections to query.

#from=

def from=(value) -> ::Array<::Google::Cloud::Firestore::V1::StructuredQuery::CollectionSelector>

Parameter

• value (::Array<::Google::Cloud::Firestore::V1::StructuredQuery::CollectionSelector>) — The collections to query.

Returns

• (::Array<::Google::Cloud::Firestore::V1::StructuredQuery::CollectionSelector>) — The collections to query.

#limit

def limit() -> ::Google::Protobuf::Int32Value

Returns

• (::Google::Protobuf::Int32Value) — The maximum number of results to return.

  Applies after all other constraints. Must be >= 0 if specified.

#limit=

def limit=(value) -> ::Google::Protobuf::Int32Value

Parameter

• value (::Google::Protobuf::Int32Value) — The maximum number of results to return.

  Applies after all other constraints. Must be >= 0 if specified.

Returns

• (::Google::Protobuf::Int32Value) — The maximum number of results to return.

  Applies after all other constraints. Must be >= 0 if specified.

#offset

def offset() -> ::Integer

Returns

• (::Integer) — The number of results to skip.

  Applies before limit, but after all other constraints. Must be >= 0 if specified.

#offset=

def offset=(value) -> ::Integer

Parameter

• value (::Integer) — The number of results to skip.

  Applies before limit, but after all other constraints. Must be >= 0 if specified.

Returns

• (::Integer) — The number of results to skip.

  Applies before limit, but after all other constraints. Must be >= 0 if specified.

#order_by

def order_by() -> ::Array<::Google::Cloud::Firestore::V1::StructuredQuery::Order>

Returns

• (::Array<::Google::Cloud::Firestore::V1::StructuredQuery::Order>) —

  The order to apply to the query results.

  Firestore guarantees a stable ordering through the following rules:

  • Any field required to appear in order_by, that is not already specified in order_by, is appended to the order in field name order by default.
  • If an order on __name__ is not specified, it is appended by default.

  Fields are appended with the same sort direction as the last order specified, or 'ASCENDING' if no order was specified. For example:

  • SELECT * FROM Foo ORDER BY A becomes SELECT * FROM Foo ORDER BY A, __name__
  • SELECT * FROM Foo ORDER BY A DESC becomes SELECT * FROM Foo ORDER BY A DESC, __name__ DESC
  • SELECT * FROM Foo WHERE A > 1 becomes SELECT * FROM Foo WHERE A > 1 ORDER BY A, __name__

#order_by=

def order_by=(value) -> ::Array<::Google::Cloud::Firestore::V1::StructuredQuery::Order>

Parameter

• value (::Array<::Google::Cloud::Firestore::V1::StructuredQuery::Order>) —

  The order to apply to the query results.

  Firestore guarantees a stable ordering through the following rules:

  • Any field required to appear in order_by, that is not already specified in order_by, is appended to the order in field name order by default.
  • If an order on __name__ is not specified, it is appended by default.

  Fields are appended with the same sort direction as the last order specified, or 'ASCENDING' if no order was specified. For example:

  • SELECT * FROM Foo ORDER BY A becomes SELECT * FROM Foo ORDER BY A, __name__
  • SELECT * FROM Foo ORDER BY A DESC becomes SELECT * FROM Foo ORDER BY A DESC, __name__ DESC
  • SELECT * FROM Foo WHERE A > 1 becomes SELECT * FROM Foo WHERE A > 1 ORDER BY A, __name__

Returns

• (::Array<::Google::Cloud::Firestore::V1::StructuredQuery::Order>) —

  The order to apply to the query results.
