Abrufen von Object.keys beim Erstellen eines Mungo-Schemas für Nicht-Objekt aufgerufen

Question

Ich habe ein paar Nachforschungen angestellt und einige Dinge ausprobiert, wie das Löschen der Sammlung usw. Nichts hat geholfen.

Code:

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.") 
    }); 

Der Fehler:

/home/ubuntu/ds_queuesystem/node_modules/mongoose/lib/schema.js:381 
    var keys = Object.keys(obj);

Schema Definition:

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

Answer 1

schemaDefinition sollte ein Object, nicht eine wörtliche sein.

Versuchen mit:

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