How to get sub-tag's value in firebase?

[Reni_Christian]

Hi Koders,

I am stuck in a situation where I want to get the values of a tag list’s sub tags.

For example:
[Firebase structure would like this]

Users
   John_Wink
      Devices
        ID2200
        Name: "Google Pixel"
        ID2300
        Name: "Samsung Galaxy S22"

   Will_harry
      Devices
        ID1212
        Name: "OPPO Find X"

I called all tags under /Users/John_Wink/Devices by setting ProjectBucket accordingly using getTagList function of Firebase. But this function only returns IDs of john_Wink. I also want values of all sub-tag of Users/John_wink/Devices/ID2200/Name and also value of Users/John_wink/Devices/ID2300/Name.

This is the error when I am trying to find length of the DeviceName Variable. Seems like GotValue firebase block is not storing list instead it is only storing one value.

I implemented this logic but it returns 2 same values for the same tag.

Any help or idea about how to get this correctly?

you want list of device name of the user?

[Reni_Christian]

Yes exactly. I want list of the devices of logged in user. But along with tag i also want values

I just tried this method but this method doesn’t seems to work for me. It throws runtime error of firebase. My problem is that I am getting two values for the same tag.

No project bucket used.

Is this what you are looking?

[Reni_Christian]

Yes something like this. I’m trying your blocks. Can you please share full blocks as this image is cropped from edges?

Otherwise

Firebase’s structure

Blocks

Both solutions worked for me. But with using firebase blocks only is quite easy to implement. Thanks a lot both you of @Still-learning @dora_paz for always helping with our doubts
