I want to add a new user in Firebase Firestore via kotlin. But i can't get positive solution to add user details for firestore. Actually it gives information about if there has a existing username but i did not add new document. When i add there existing username it show toast message and log. But the second chance which i make to do, does not works correctly, neither happening antyhing.
private fun addUserToFireStore(
) {
auth.createUserWithEmailAndPassword(email, password).addOnSuccessListener {
updateUser()
}.addOnFailureListener { e ->
}
}
private fun updateUser() {
val rootRef = FirebaseFirestore.getInstance()
val allUsersRef = rootRef.collection("ProfPic")
val cu = auth.currentUser
val userNameQuery = allUsersRef.whereEqualTo("Username", username)
userNameQuery.get().addOnCompleteListener { task ->
if (task.isSuccessful) {
for (document in task.result) {
if (document.exists()) {
Log.d("TAG", "username already exists")
Toast.makeText(
this@Logmenu2,
"Exist",
Toast.LENGTH_LONG
).show()
//Do what you need to do with the userName
} else {
Toast.makeText(
this@Logmenu2,
"Created",
Toast.LENGTH_LONG
).show()
val profID = auth.currentUser?.uid
val user = hashMapOf(
"Username" to username,
"Email" to email,
"Fullname" to fullname,
"Rank" to rank,
"Rating" to raiting,
"downloadUs" to downloadUrl,
"userID" to profID
)
fstore.collection("ProfPic").document(profID.toString()).set(user)
.addOnSuccessListener { documentReference ->
}
Toast.makeText(
this@Logmenu2,
"Created",
Toast.LENGTH_LONG
).show()
}
}
} else {
Log.d("TAG", "Error getting documents: ", task.exception)
}
}
}
}
UPDATE:
These code below worked for me
var userExist = false
val mQuery: Query =
fstore.collection("ProfPic")
.whereEqualTo("Username", username)
mQuery.get().addOnCompleteListener { task ->
Log.d(ContentValues.TAG, "checkingIfusernameExist: checking if username exists")
if (task.isSuccessful) {
for (document in task.result) {
val userNames = document.getString("Username")
if (userNames == username) {
Log.d(
ContentValues.TAG,
"checkingIfusernameExist: FOUND A MATCH -username already exists"
)
Toast.makeText(
this,
"username already exists",
Toast.LENGTH_SHORT
)
.show()
userExist = true
break
}
}
if (userExist == false) {
