What is the db.collection.stats() command in mongoose?

问题

I want to check one collection's information just like the db.collection.stats() command in origin MongoDB

How can I do it in mongoose on schema or on model?

回答1:

Had the same problem and managed to query it this way:

 YourModel.collection.stats(callback);

You basically access a Model's native interface via the collection property (this is not the collection name, but a property in fact called collection). You can then use any native functions on this object.

回答2:

You can run any arbitrary command via executeDbCommand so since stats is just a database command, you can runCommand that stats() does under the hood:

db.runCommand( { collstats : collectionName } );
