How i can update data firebase with specific key in golang?

I am using golang and firego for connecting to Firebase. I want to update my data Statusfrom ON to OFF with key IDAgent: 7. This is my Database Structure

Assumption : I don't know child active_chat. How can i update data in active_chat/-Koja8GuFplEN3kjbfPO where IDAgent = 7

I have tried this code

x := map[string]string{"Status": "OFF"}
ref.OrderBy("IDAgent").EqualTo("7").Update(x)

but this code wrong query.

In two ways you can do, as per Firebase doc with firego client library. Drafted answer based on from firego README.md.

Note: You have not provided the complete path of the structure, I have drafted the answer based on screenshot. So update your JSON path accordingly.

Approach 1:

f := firego.New("https://my-firebase-app.firebaseIO.com/active-chat/Koja8GuFpIEN3kjbfPO.json", nil)

x := map[string]string{
   "Status": "OFF",
}
if err := f.Update(x); err != nil {
  log.Fatal(err)
}

Approach 2:

f := firego.New("https://my-firebase-app.firebaseIO.com", nil)
f = f.Ref("/active-chat/Koja8GuFpIEN3kjbfPO.json")

x := map[string]string{
   "Status": "OFF",
}
if err := f.Update(x); err != nil {
  log.Fatal(err)
}

Update for 2022:

package main
import (
"context"
"fmt"
"time"
firestore "cloud.google.com/go/firestore"
firebase "firebase.google.com/go"
"google.golang.org/api/option"
)
type (
myDocument struct {
Cars       []Car  `firestore:"cars"`
carsCount  int64  `firestore:"car_count"`
UpdateTime string `firestore:"update_time"`
}
Car struct {
Name      string `firestore:"name"`
YearBuilt string `firestore:"year_built"`
}
)
func getFirebaseClient(ctx context.Context) (*firestore.Client, error) {
sa := option.WithCredentialsFile("Path_To_Firebase_Key")
// Initialize firebase app with admin privileges
app, err := firebase.NewApp(ctx, nil, sa)
if err != nil {
err = fmt.Errorf("getFirestoreClient failed: %s", err)
return nil, err
}
// Create client
client, err := app.Firestore(ctx)
if err != nil {
err = fmt.Errorf("failed to connect to firestore: %v", err)
return nil, err
}
return client, nil
}
func main() {
// Create context
ctx := context.Background()
// Get firebase client
client, err := getFirebaseClient(ctx)
if err != nil {
panic(err)
}
// Create car struct
newCar := Car{
"Volvo_Series1",
"1920",
}
// Update time
newTime := time.Now().UTC().Format("Monday, 01-02-2006 15:04:05")
// Updates to document
updates := []firestore.Update{
{Path: "cars", Value: firestore.ArrayUnion(newCar)},
{Path: "car_count", Value: firestore.Increment(1)},
{Path: "update_date", Value: newTime},
}
// OPTION A)
// Create collection reference
collectionRef := client.Collection("cars")
// Create document reference
docRef := collectionRef.Doc("12345")
// Update document
_, err = docRef.Update(ctx, updates)
if err != nil {
err := fmt.Errorf("failed updating document: %s from %s collection %v", docRef.ID, docRef.Parent.ID, err)
panic(err)
}
// OPTION B)
_, err = client.Collection("cars").Doc("12345").Update(ctx, updates)
if err != nil {
err := fmt.Errorf("failed updating document: %s from %s collection %v", docRef.ID, docRef.Parent.ID, err)
panic(err)
}
}
