size() public

Returns the size of the collection by executing a SELECT COUNT(*) query if the collection hasn’t been loaded, and by calling collection.size if it has. If the collection will likely have a size greater than zero, and if fetching the collection will be needed afterwards, one less SELECT query will be generated by using #length instead.
