Ich bin mit Rest-API mit mongodb und m ongoose, ich habe alle relevanten Änderungen an app.js vorgenommen und kann immer noch keine Funktion von mongodb in node.js ausführen. Ich habe App.js und Router-Datei, die Form-Router mit dieser Abfrage ist angehängt.

können Sie den Inhalt in models/forms.js veröffentlichen? Das scheint das Problem zu sein. Ich schätze, Sie haben entweder überhaupt keine Create-Funktion exportiert, oder Sie haben es falsch geschrieben oder möglicherweise Create erstellt. – Paul

Ich habe forms.js und forms-1.js in der obigen Abfrage hinzugefügt, bitte sehen Sie es sich an und ich weiß auch nicht, wie man create function exportiert? können Sie bitte auch in dieser Hinsicht helfen –

Ok, ja, wenn "Formulare" Ihr Mungo-Modell ist, dann ist die korrekte Syntax ist forms.create (... .) mit einem Kleinbuchstaben c.

* UPDATE * Ok, von Ihren Kommentaren bin ich immer noch nicht sicher über Ihre App-Struktur; Dinge sind eine Berührung, die die Art, wie du sie hast, verwirrt.

In jedem Fall, was Sie wollen in Ihrem Router haben, ist das Modell, dass Mungo produziert. Sie können es auf diese Weise tun:

var Form = mongoose.model('form'); // note that this assumes you've already called require on your ./models/forms.js file to run it and get the schema into mongoose 

formRouter.route('/') 
.post(function(req,res,next){ 
    Form.create(/* your args here and callback and stuff */); 
});

Ich habe die Syntax geändert und machte es klein c und immer noch nicht ausgeführt, ich habe wieder den Fehler in meiner Abfrage oben hinzugefügt, forms-1.js ist die Datei, in der wir das Schema definiert haben und forms.js ist die Datei, in der ich eine Mungoverbindung hergestellt habe –
