node.js - How to create mongoose schema dynamically?

Question

I have an app that works on node.js with MongoDB and mongoose. My app simply sends/deletes/edits form data and for that, I have such mongoose model:

var mongoose = require('mongoose');

module.exports = mongoose.model('appForm', {
    User_id : {type: String},
    LogTime : {type: String},
    feeds : [   
    {
        Name: {type: String},
        Text : {type: String},
    }
    ]
});

and that works just fine!

Now, I would like to add a function to the form so that the user can add a field(or fields) to form and enter a text in it and post it. Creating that dynamic functionality on the client side is no problem but I understand that my mongoose.model has to be correctly structured. My question is: how do I add that variable values(dynamically created form data name and its text) to mongoose schema?

I see that using strict: false and Schema.Types.Mixed is advised. however, I can't figure out... What I have tried:

var mongoose = require('mongoose');
var Schema = mongoose.Schema;
var feedSchema = new Schema({strict:false});

module.exports = mongoose.model('appForm', feedSchema);

Any tips? Thanks in advance!

Apply the strict: false option to your existing schema definition by supplying it as a second parameter to the Schema constructor:

var appFormSchema = new Schema({
    User_id : {type: String},
    LogTime : {type: String},
    feeds : [new Schema({
        Name: {type: String},
        Text : {type: String}
    }, {strict: false})
    ]
}, {strict: false});

module.exports = mongoose.model('appForm', appFormSchema);

If you want to leave feeds as fully schemaless, that's where you can used Mixed:

var appFormSchema = new Schema({
    User_id : {type: String},
    LogTime : {type: String},
    feeds : [Schema.Types.Mixed]
}, {strict: false});

module.exports = mongoose.model('appForm', appFormSchema);
