我正在创建一个Student数据模式,其中一个学生包含每个学期的分数。我想创建一个Sem数组,其中Sem_Schema必须是ref对象。通过使用Sem_Schema,我想创建Sem_Schema对象的sem数组。请帮忙。
var Student_Data_Schema = new mongoose.Schema({
name:{type:String,default:"Rahul Kandiboina", required: true},
reg_no:{type:String,default:"315175711057", required: true},
dob:{type:String,default:"july 3 1998"},
BG:{type:String,default:"o +ve", required: true},
ctg:{type:String,default:"B", required: true},
caste:{type:String,default:"BC", required: true},
EAMCET_Rank:{type:String,default:"29000", required: true},
ECET_Rank:{type:String,default:"123", required: true},
SSC_M:{type:String,default:"9.3", required: true},
Inter_M:{type:String,default:"960", required: true},
DEP_M:{type:String,default:"870", required: true},
BTECH_AGG:{type:String,default:"7.5", required: true},
GRE:{type:String,default:"60", required: true},
GATE:{type:String,default:"120", required: true},
CAT:{type:String,default:"10000", required: true},
TOEFL:{type:String,default:"100", required: true},
E_MAIL:{type:String,default:"rahulkandiboina9@gmail.com", required:
true},
// Father :{},
// Mother :{},
// Bro :{},
// Sis :{},
Pre_Add :{
D_no:{type:String},
Street:{type:String},
village:{type:String},
town:{type:String},
District:{type:String},
State:{type:String},
Pin:{type:String}
},
Per_Add:{
D_no:{type:String},
Street:{type:String},
village:{type:String},
town:{type:String},
District:{type:String},
State:{type:String},
Pin:{type:String}
},
Marks:{
CGPA:{type:Number},
B_LOGS:{type:Number},
Sem :[Sem_Schema]
}
})
var Sem_Schema = new mongoose.Schema({
SGPA :{type:String},
CGPA :{type:String},
B_Logs :{type:String},
Sem_Att :{type:String},
T_Sess :{type:String}
})
我想将Sem_Schema嵌套到Sem数组中,但是错误像这样
F:\ Project \ WEB \ NewPro \ NodeJs \ node_modules \ mongoose \ lib \ schema.js:398
抛出新的TypeError('模式数组路径' + prefix + key + '
的无效值'); ^TypeError:模式数组路径
Marks.Sem
的值无效 模式添加 (F:\ Project \ WEB \ NewPro \ NodeJs \ node_modules \ mongoose \ lib \ schema.js:398:13) 在Schema.add (F:\ Project \ WEB \ NewPro \ NodeJs \ node_modules \ mongoose \ lib \ schema.js:407:14) 在新的架构 (F:\ Project \ WEB \ NewPro \ NodeJs \ node_modules \ mongoose \ lib \ schema.js:114:10) 在对象。 (F:\ Project \ WEB \ NewPro \ NodeJs \ Models \ dept.js:3:27)在Module._compile (internal / modules / cjs / loader.js:688:30)在 Object.Module._extensions..js(内部/模块/cjs/loader.js:699:10) 在Module.load(internal / modules / cjs / loader.js:598:32)在 tryModuleLoad(内部/模块/cjs/loader.js:537:12)在 Function.Module._load(internal / modules / cjs / loader.js:529:3)位于 Module.require(internal / modules / cjs / loader.js:636:17)在require (内部/模块/cjs/helpers.js:20:18)。 (F:\ Project \ WEB \ NewPro \ NodeJs \ Router \ college.js:3:14)在 Module._compile(内部/模块/cjs/loader.js:688:30)位于 Object.Module._extensions..js(内部/模块/cjs/loader.js:699:10) 在Module.load(internal / modules / cjs / loader.js:598:32)在 tryModuleLoad(内部/模块/cjs/loader.js:537:12)

像这样在Student_Data_Schema之前声明您的Sem_Schema。这里发生的是,当您在架构后引用此对象时,它不知道这是什么导致Sem_schema。因此将代码更改为
var Sem_Schema = new mongoose.Schema({
SGPA :{type:String},
CGPA :{type:String},
B_Logs :{type:String},
Sem_Att :{type:String},
T_Sess :{type:String}
})
// after this add the next schema
var Student_Data_Schema = new mongoose.Schema({
name:{type:String,default:"Rahul Kandiboina", required: true},
reg_no:{type:String,default:"315175711057", required: true},
dob:{type:String,default:"july 3 1998"},
BG:{type:String,default:"o +ve", required: true},
ctg:{type:String,default:"B", required: true},
caste:{type:String,default:"BC", required: true},
EAMCET_Rank:{type:String,default:"29000", required: true},
ECET_Rank:{type:String,default:"123", required: true},
SSC_M:{type:String,default:"9.3", required: true},
Inter_M:{type:String,default:"960", required: true},
DEP_M:{type:String,default:"870", required: true},
BTECH_AGG:{type:String,default:"7.5", required: true},
