How to Read from the Realtime Database

[IkoniStudio]

Apologies first, I'm self-taught so my knowledge is limited. I need to read information from the realtime database for my mobile game (for now its just Android), I was able to have it working before but I think this plugin and instructions have been updated and now my code is not working.

In my realtime database my .json code is like so:

{
  "version_android": 5.5,
  "version_ios": 1
}

I just need the read the versions in order to proceed with the game or to send the player to an update UI.

In my game I call this code first to login in anonymously:

Firebase.Auth.signup_succeeded.connect(_on_FirebaseAuth_auth_succeeded)
Firebase.Auth.login_failed.connect(_on_login_failed) # example not connect to internert
Firebase.Auth.login_anonymous() 

This appears to work. I can login anonymously - so I can successfully connect to Firebase.

Next, I had this function - which doesn't appear to work anymore:

func _on_FirebaseAuth_auth_succeeded(_auth):	
	db_ref = Firebase.Database.get_database_reference("config")
	db_ref.new_data_update.connect(_on_db_new_data_update)
	db_ref.patch_data_update.connect(_on_db_patch_data_update) 

I'm looking at the instructions and it appears I need to update this to:

func _on_FirebaseAuth_auth_succeeded(_auth):	
	db_ref = Firebase.Database.get_database_reference("data", {})
	db_ref.new_data_update.connect(_on_db_new_data_update)
	db_ref.patch_data_update.connect(_on_db_patch_data_update) 

And then, following the instructions if I call to print like so:

func _on_db_data_update(resource):
	print(resource)

Except this (_on_db_data_update) never executes. I feel if I could get this to execute I could then do what I did before for testing: resource.key check and resource.data check. Any help would be appreciated, thanks.

You can just use ("config", {}).

I have checked the .env file, and the web_app data in Firebase matches and it does. I guess it would have to in order to get through the first step on anonymous login.

If you've got a named database, you have to put the name into the .env file as well. If it's the default, that should still work, assuming your database structure is what you say. How are you updating the database to check it? Do none of the signals ever fire? What about the login_succeeded signal?

These things aren't broken for me, so I'll need more context if possible.

It just worked for me when I changed the call to:

db_ref = Firebase.Database.get_database_reference("")

I have no idea why, but it executed and called the function: func _on_db_data_update(resource) as expected.

I may know the issue. I think I remember I had to fix an issue on another project and haven't committed it back to the most-recent codebase. I'll check again.
