inserted_count¶

Number of documents inserted

upserted_count¶

Number of documents upserted

matched_count¶

Number of documents matched for an update or replace operation.

deleted_count¶

Number of documents removed

modified_count¶

Number of documents actually modified by an update operation. This is not necessarily the same as "matched_count" if the document was not actually modified as a result of the update.

This field is not available from legacy servers before version 2.6. If results are seen from a legacy server (or from a mongos proxying for a legacy server) this attribute will be "undef".

You can call "has_modified_count" to find out if this attribute is defined or not.

upserted¶

An array reference containing information about upserted documents (if any). Each document will have the following fields:

• index — 0-based index indicating which operation failed
• _id — the object ID of the upserted document

upserted_ids¶

A hash reference built lazily from "upserted" mapping indexes to object IDs.

inserted¶

An array reference containing information about inserted documents (if any). Documents are just as in "upserted".

inserted_ids¶

A hash reference built lazily from "inserted" mapping indexes to object IDs.

write_errors¶

An array reference containing write errors (if any). Each error document will have the following fields:

• index — 0-based index indicating which operation failed
• code — numeric error code
• errmsg — textual error string
• op — a representation of the actual operation sent to the server

write_concern_errors¶

An array reference containing write concern errors (if any). Each error document will have the following fields:

• index — 0-based index indicating which operation failed
• code — numeric error code

op_count¶

The number of operations sent to the database.

batch_count¶

The number of database commands issued to the server. This will be less than the "op_count" if multiple operations were grouped together.

assert¶

Throws an error if write errors or write concern errors occurred.

assert_no_write_error¶

Throws a MongoDB::WriteError if "count_write_errors" is non-zero; otherwise returns 1.

assert_no_write_concern_error¶

Throws a MongoDB::WriteConcernError if "count_write_concern_errors" is non-zero; otherwise returns 1.

count_write_errors¶

Returns the number of write errors

count_write_concern_errors¶

Returns the number of write errors

last_code¶

Returns the last "code" field from either the list of "write_errors" or "write_concern_errors" or 0 if there are no errors.

last_errmsg¶

Returns the last "errmsg" field from either the list of "write_errors" or "write_concern_errors" or the empty string if there are no errors.

last_wtimeout¶

True if a write concern timed out or false otherwise.
