试试这个（未经测试）：

var userSchema = new Schema({ firstname: String, lastname: String });

// assign a function to the "statics" object of our userSchema
userSchema.statics.create = function (userObject) {
    console.log('Creating user');
    // use Function.prototype.call() to call the Model.create() function with the model you need
    return mongoose.Model.create.call(this.model('User'), userObject);
};
