从 Dialogflow 上的循环设置参数输出上下文

Question

i make some loop for calling data from firebase, how to set document id as parameters for my output context when i selected the data from document?

this my code for function daftaKota

function daftarKota(agent){
const query = db.collection('kota');
return query.get().then(s =>{
    if (s.empty){
        agent.add('belum ada kota yang didaftarkan oleh Pemilik');
        agent.add('untuk mengakses menu lainnya silahkan ketikan "menu"');
        agent.context.set('menu',2);
    } else {
      agent.add('berikut daftar kota');
      s.forEach(doc =>{
        agent.add(new Suggestion(doc.data().nama_kota));
        agent.context.set('lihat-toko',5,{'id_kota' : doc.id,'nama_kota' : doc.data().nama_kota});
      });
    }
});

this my code for function daftarToko

function daftarToko (agent){
const context = agent.context.get('lihat-toko');
const idKota = context.parameters.id_kota;
const nKota = agent.parameters.kota;

const query = db.collection('toko').where('id_kota','==',idKota);
return query.get().then(s =>{
  if (s.empty){
    agent.add('Belum ada Toko yang didaftarkan di kota ini');
    agent.add('untuk mengakses kota lainnya silahkan ketikan "kembali"');
    agent.context.set('order',2);
  }else{
    agent.add('berikut daftar toko di kota '+nKota);
    s.forEach(doc => {
      agent.add(new Card({title : doc.data().nama_toko, imageUrl : doc.data().gambar_toko}));
      agent.add(new Suggestion(doc.data().nama_toko));
      agent.context.set('lihat-kue',5,{'id_toko' : doc.id});
    });
  }
});

and this the Intent Map

intentMap.set('Daftar Kota',daftarKota);
intentMap.set('Daftar Toko',daftarToko);

this my intent "Daftar Kota"

see at paramers :

1. i selected "kota : Yogyakarta",
2. but the id_kota is the document id of nama_kota "Banjarmasin", not the id of "Yogyakarta"

Answer 1

You're not showing the query that you're using, or where you're storing the parameters you get, but in your loop you're not actually checking to see if nama_kota matches the kota that is sent through the parameters. So it is changing the context every time it goes through the loop, and ends up with the new parameters from the last time through.

One solution would be to check if they match and, when they do, set the context.

  s.forEach(doc =>{
    agent.add(new Suggestion(doc.data().nama_kota));
    if( parameters.kota === doc.data().nama_kota ){
      agent.context.set('lihat-toko',5,{'id_kota' : doc.id,'nama_kota' : doc.data().nama_kota});
    }
  });
