몽구스 스키마를 만들 때 객체가 아닌 객체에서 Object.keys가 호출되었습니다.

Question

저는 몇 가지 조사를 해본 결과 콜렉션을 삭제하는 등 몇 가지 시도를했습니다.

코드 :

MongoClient.saveData = function(schemaDefinition, data, collectionName){ 
    console.log("Schema definition: "+schemaDefinition+" collection name: "+collectionName); 
    var RecordSchema = new mongoose.Schema(schemaDefinition);//{ Email: String, FirstName: String});//({any: Schema.Types.Mixed }); 
    console.log("Schema created."); 
    var RecordModel = mongoose.model(collectionName, RecordSchema); 
    console.log("Model created. Inserting in batches.") 
    RecordModel.insertMany(data) 
    .then(function(mongooseDocuments) { 
     console.log("Insertion was successful."); 
    }) 
    .catch(function(err) { 
     console.log("Error while inserting to DB.") 
    });

스키마 정의 :

var schemaDefinition = "{SCHID: String, Priority: Number, Status: String, Json: Schema.Types.Mixed})"; 

Answer 1

schemaDefinitionObject 아닌 문자이어야한다.

시도해보십시오 :

var schemaDefinition = { 
    SCHID: String, 
    Priority: Number, 
    Status: String, 
    Json: Schema.Types.Mixed 
};
