//reportconfig.js    
//Load up the report model
var Report = require('../models/report');
console.log('Report ' + Report);

//expose this function to our app using module.exports
module.exports = function(req) {
    console.log('exporting' + req.body.address);
    var newReport = new Report();
    console.log('local ' + newReport.local.address);

    newReport.address = req.body.address;
    newReport.city = req.body.city;
    newReport.state = req.body.state;

    console.log('save ' + newReport.save);

    newReport.save(function(err) {
        console.log('saving ' + newReport.address);
        if(err) {
            console.log('error ' + err);
            throw err;
        }
        //return newReport;
    })

// define the schema for our user model
var reportSchema = mongoose.Schema({

    local : {

        city : String,
        state : String

    }

});


// create the model for users and expose it to our app
module.exports = mongoose.model('Report', reportSchema);

当我发布到/ report时会发生什么，调用模型并调用save。数据库获取一个新条目，但它只有_id，而不是任何其他字段。没有错误。知道我做错了什么吗？如果你问，我可以提供更多信息。上面的代码来自三个单独的文件由于打印报告有效，因此模型正确加载。 newReport的所有字段也都有效。

Answer 1

您的架构中不需要本地。当您保存使用未在架构中定义的newReport.address时。如果你想保持相同的结构，它将是newReport.local.address。以下是定义mongoose模式方法的文档：http://mongoosejs.com/docs/guide.html

mongoose.model('Report', reportSchema);

var reportSchema = mongoose.Schema({

   address : String,
   city : String,
   state : String

});

Answer 2

newReport.address等未在Schema中定义。因此，为了维护它，Mongoose将它们作为.save()的一部分删除。

要匹配架构，读取和分配需要使用newReport.local：

newReport.local.address = req.body.address;
newReport.local.city = req.body.city;
newReport.local.state = req.body.state;

console.log('saving ' + newReport.local.address);

或者，如果没有使用，local可以从Schema中删除：

var reportSchema = mongoose.Schema({
    address : String,
    city : String,
    state : String
});

为什么我的Mongo文档无法通过Mongoose正确保存？
