我的文档何时使用Mongoose保存功能保存？

Question

My question is in the function below in the commented code.

newUser = new User();
newUser.save(function(err){
            if(err) console.log('error saving user');
            // is my user saved at this point? Can I modify
            // the user in here or is this pre-save?
            });

Answer 1

As soon as the code is executed it is saved. There is some validation that occurs in the middleware, but it is instant otherwise.
