Is it possible to get database reference without childByAutoId (). Key? - swift

Question

Is there a way to dynamically get a child database from the parent instance, without having to use childByAutoId () ?
{
"artists" : {
"artists_id_1" : {
"name" : "Atif Aslam",
"genre" : "Rock"
},
"artists_id_2" : {
"name" : "Arijit Singh",
"genre" : "Rock"
}
}
}
we usually refer to the path, and listener the items the DataBase...Example:
Database.database().reference().child("artists").child("artist_id_1").observeSingleEvent(of: .value, with: { (snapshot) in
if let dictionary = snapshot.value as? [String: AnyObject] {
print("\(String(describing: dictionary["name"] as? String))")
}
}, withCancel: nil)
it would only work for the first item. Because, it would not be dynamic. What is normally used is the following example below ...
{
"artists" : {
"-KeZUDrJv555kteAcssL-" : {
"name" : "Atif Aslam",
"genre" : "Rock"
},
"-KeZUVXFIQdO7JiyRYk-" : {
"name" : "Arijit Singh",
"genre" : "Rock"
}
}
}
Database.database().reference().child("artists").childByAutoId().observeSingleEvent(of: .value, with: { (snapshot) in
if let dictionary = snapshot.value as? [String: AnyObject] {
print("\(String(describing: dictionary["name"] as? String))")
}
}, withCancel: nil)
Anyway, I do not know if it was clear, anything can comment before answering. Thank you

Answer 1

To display all artists in your database, load the artists node and loop over snapshot.children:
Database.database().reference().child("artists").observe(.value) { (snap:DataSnapshot) in
for child in snapshot.children {
print(child.key)
}
}
For this and more examples, I recommend reading the Firebase documentation, specifically the section on reading and writing lists.

I dont know if i understand your question correctly or what you are trying to do but maybe you can try
Database.database().reference().child("artists").observe(.value) { (snap:DataSnapshot) in
// This should print out your childIds
print(snap.key)
// This should print out the values after them
print(snap.value)
}
