Firebase permission-denied

Question

I'm a newbie in firebase.

How do I get through this below rule?

service cloud.firestore {
  match /databases/{database}/documents {
    match /{document=**} {
      allow read, write: if false;
    }
  }
}

I've tried to change the rule to below,

{
  "rules": 
   {
    ".read": true,
    ".write": true,
   }
}

but there's an error of

mismatched input '{' expecting {'function', 'service', 'syntax'}

Below is the db structure.

Currently, this is my code (which keeps returning Permission-denied):

    // [START initialize_database_ref]
    mDatabase = FirebaseDatabase.getInstance().reference
    // [END initialize_database_ref]

    val result = HashMap<String, Any> ()
    result.put("timestamp", getCurrentTime())
    result.put("user_id", USER_ID)
    result.put("x_position", -1)
    result.put("y_position", -1)

    mDatabase!!.ref.child("raw data").child("Z9QD79lDzP7MpD6feWeJ").setValue(result).addOnFailureListener(object : OnFailureListener {
        override fun onFailure(@NonNull e: Exception) {
            Log.d("firebase", e.localizedMessage)
        }
    })

Any help would be appreciated! Thanks :)

Answer 1

I was able to solve the problem by switching from Cloud Firestore to Realtime Database, and then changing the rule. (After I've changed this, there was no more error showing!)

Answer 2

For others struggling with this problem, the proper solution is to change the false in

service cloud.firestore { 
    match /databases/{database}/documents {
        match /{document=**} { 
            allow read, write: if false; 
        } 
    }
}

To true while testing. Don't forget to add additional security when going live with your project!
