我正在尝试进行一次Post请求,将数据插入到Mongo数据库中。为此,我使用了mongoose
。我已经创建了下面这样的mongoose Schema
-
const countrySchema = mongoose.Schema({
country_id: {
type : Number,
required: true,
unique : true
},
country_name : {
type : String,
required : true,
unique : true
},
country_description : {
type : String,
required : true,
unique : true
},
country_currency : {
type : String,
required : true,
unique : true
},
country_capital : {
type : String,
required : true,
unique : true
},
country_numberof_districs : {
type : Number,
required : true
},
country_createdat : {
type : Date,
required : true
},
country_districs : {
districs : [
{
distric_id : {
type : Number,
// required : true,
},
distric_name : {
type : String,
// required : true,
},
distric_description : {
type : String,
// required : true,
},
distric_famous_for : {
type : String,
// required : true
}
}
]
}
});
以下是我的POST方法:
router.post('/addcountry', (request, response, next) => {
const district = [];
district.push({
distric_id: request.body.distric_id,
distric_name : request.body.distric_name,
distric_description : request.body.distric_description,
distric_famous_for : request.body.distric_famous_for
});
let newCountry = new country({
country_id : request.body.country_id,
country_name : request.body.country_name,
country_description : request.body.country_description,
country_currency : request.body.country_currency,
country_capital : request.body.country_capital,
country_numberof_districs : request.body.country_numberof_districs,
country_createdat : new Date(),
country_districs : {
districs : [district]
}
});
country.addCountry(newCountry, (err, country) =>{
console.log('came here');
if(err){
response.json({
success : false,
message : 'failed to add country' + err
});
}else {
response.json({
success : true,
message : 'country added successfully'
});
}
});
});
我用 Postman
进行了测试。没有 districs
部分,它的功能很好。我尝试发布下面的对象 -
{
"country_id" : 909773,
"country_name" : "USA",
"country_description" : "UNITED STATRE",
"country_currency" : "USD",
"country_capital" : "NEWYORK",
"country_numberof_districs" : 100,
"country_districs": {
"districs":
[
{
"distric_id": 777,
"distric_name" : "melbourne",
"distric_description" : "no des",
"distric_famous_for" : "beaches"
},
{
"distric_id": 900,
"distric_name" : "sydney",
"distric_description" : "no des",
"distric_famous_for" : "beaches"
}
]
}
}
结果如下所示 -
{
"_id" : ObjectId("58e37b5c3c6b07153600a7f6"),
"country_id" : 909773,
"country_name" : "USA",
"country_description" : "UNITED STATRE",
"country_currency" : "USD",
"country_capital" : "NEWYORK",
"country_numberof_districs" : 100,
"country_createdat" : ISODate("2017-04-04T10:54:20.726Z"),
"country_districs" : {
"districs" : [
{
"_id" : ObjectId("58e37b5c3c6b07153600a7f7")
}
]
},
"__v" : 0
}
注意:首先我尝试了一个区,但它也没有起作用。我该如何添加这个区域对象(可能有多个,比如区域数组),并如何遍历所有区域对象。希望你能帮助我。
let newCountry = new country({ country_districs : { districs : req.body.country_districts.districts } });
,同时也要包括其他字段... - Jyotman Singhdistricts
键不是您必须要的,则可以通过将架构中的变量定义为数组来简单存储对象数组,并将其存储到相应的键中。如果您愿意,我可以提供一个简单的示例,但前提是districts
不是必备条件。 - Ajitej Kaushikcountry_districs : { districs : [district] }
改为:country_districs : { districs : district }
- Cédric De Dyckerdistrics:req.body.country_districts.districs
。感谢您的帮助。如果您能将此作为答案,我可以接受。无论如何,感谢所有帮助过我的人。祝你好运,干杯! - caldera.sac
