Im trying to delete this data in the app but im not sure how to retrieve the uid of the one i need to delete:
so the first id is the current users id but how do i get the next unique id fo i can delete the records "test" and "Apple"
this is how i upload the data to the database:
var currentUid = mAuth.currentUser?.uid
val myRef = database.getReference("Users")
val myRefCategory = myRef.child(currentUid!!).child("Following")
fun sendDataToDatabase(category: String) {
myRefCategory.push().setValue(category)
}
how do i get the "MLt1lk1wtyvqLtQGZRF" and "MLt1bpUmJmAkjz_7tGN"?
The key you're looking for is in the DatabaseReference returned by push() .
val ref = myRefCategory.push()
val key = ref.key // this is your key
ref.setValue(...)
