Or you could put all data of a user into a JSON structure, then save it by rex_firebase plugin.
Thanks for the hints
I'm using the Firebase plugin, Authentifaction plugin, Query Plugin and the Firebase API 3 plugin. I try to access the Database after the login was successfully.
// grants write access to the owner of this user account
// whose uid must exactly match the key ($user_id)
".write": "$user_id === auth.uid",
".read": "auth != null && auth.uid == $user_id"
This are my rules, but with this rules the access will be denied.
Any idea why this happens?
