RethinkDB - Updating nested array

Question

I have a survey table that looks like so:

{
  id: Id,
  date: Date,
  clients: [{
    client_id: Id,
    contacts: [{
      contact_id: Id,
      score: Number,

Better late than never

I had your same problem and i could solve it with two ways:

With specific client_id

r.db('nameDB').table('nameTable').get('idRegister')
.update({'clients': r.row('clients')
    .map(elem=>{
        return r.branch(
            elem('client_id').eq('your_specific_client_id'),
            elem.merge({
                contacts: elem('contacts').map(elem2=>
                    r.branch(
                        elem2('contact_id').eq('idContact'),
                        elem2.merge({
                            score: 99999,
                            feedback: 'yourString'
                        }),
                        elem2
                    )
                )
            }),
            elem
        )
    })
})

Without specific client_id

r.db('nameDB').table('nameTable').get('idRegister')
.update({'clients': r.row('clients')
    .map(elem=>
        elem.merge({
            contacts: elem('contacts').map(elem2=>
                r.branch(
                    elem2('contact_id').eq('idContact'),
                    elem2.merge({
                        score: 99999,
                        feedback: 'yourString'
                    }),
                    elem2
                )
            )
        })
    )
})

I hope that it works for you, even when happened much time ago
