Consider enhancing your RethinkDB database by incorporating new components into a nested array

After referencing the example provided here, I have included an additional level to notes, where it is mapped to an object containing arrays within its elements.

{
    id: 10001,
    name: "Bob Smith",
    notes: {
        alpha:['note1','note2','note3'],
        beta:['note1','note2','note3']
    }
}

I am facing difficulty in appending elements to both alpha and beta. Various attempts, such as the following, have not been successful:

update({ 
    notes:{  
        alpha: r.row("alpha").append('note4')  
    } 
})

I seem to be stuck and unable to find a solution on my own. Any assistance or guidance would be greatly appreciated~

The error message I encountered was No attribute 'alpha' in object:

Answer №1

If you want to modify the notes fields in a database table called 'user', you can use the code snippet below:

r.db('test')
 .table('user')
 .get('10001')
 .update({
   notes: {
     alpha: r.row('notes')('alpha').append('note4'),
     beta: r.row('notes')('beta').append('note4')
   }
 }).run();
