How to store sub-data in Firebase? (For an online quiz app)

[Salman_Dev]

I think it's possible, but I've never tried web components

[Mayank_Kumar]

Same with me but I found a tutorial in the community itself : https://community.appinventor.mit.edu/t/firebase-with-web-component/ but it is very confusing.

[Salman_Dev]

what if you make it like this

[Mayank_Kumar]

Append Value is a good option but how will I get rid of the older values?

@Mayank_Kumar

but how will I get rid of the older values?

hmm, I think append value is a bad way

[Mayank_Kumar]

I think I should close this topic because I have to present the app at 1:00 pm and I don't really think anyone will be online at this time. If your timezone is different, then note that it's 12:40 already, so I can do nothing but I will surely send the .aia of the app.

[Salman_Dev]

Okay, I got it

[Salman_Dev]

Maybe this method can be used :

@Mayank_Kumar

Yes, I thought so but people who are low on internet will create an intense problem as the network lag will cause data to get updated but it will change all other data back to what it was when the device read it. Is there anything I could do to prevent this?

sorry for now, there is still no way to do it because there are still some blocks that are not available

I did my best to explain everything, what are you having trouble with? (You do have to adopt a different mindset to the normal way of doing firebase things in AI2 )

[Salman_Dev]

Besides that, why would you want to use sub-tags, even though you can use regular tags which are easier and more comfortable to use?

[Mayank_Kumar]

I have said it before

I know that, but I mean why do you want to create sub-tags when you can use regular tags, because those subtags can only work together as if a value is updated it has to update all, but if it is a regular tag you don't need to update all the values ​​that are used, and tags you only need to select one tag and edit the value in it without having to update all the values ​​in other tags.
I hope you can understand what I mean

[TIMAI2]

Not sure why sub tags are a bad thing? That is the whole point of the firebase data structure.

[Salman_Dev]

@TIMAI2

That is the whole point of the firebase data structure.

I think you are right @TIMAI2, I hope you can make a project that can help on this topic
btw thank you

Firebase Not Retrieving TagList

Let us simplify: Firebase: [image] With ProjectBucket = MacTags Taglist returned = ["MoreMacTags", "FA:B7:F7:63:17:C1", "0A:7B:CF:AF:06:F9"] [image] With ProjectBucket = MacTags/MoreMacTags Taglist returned = ["mactag1", "mactag2"] [image]

The tag structure in the 4 year old experimental app is an example of very fine grained data storage, for the game Rock Paper Scissors, capable of managing multiple matches and multiple players.

MultiPlayer Rock Paper Scissors on FireBaseDB

I haven't used Firebase in a while, maybe because the stock MIT emulator was too old to support it.
I can't vouch for the completion of the app, but the important thing to learn from it is how to build up Firebase tags by JOINing key parts separated by '/', avoiding storing lists, and by not worrying about redundant storage.

[Mayank_Kumar]

I will try both of your suggestions and tell.

How to Search any tag in Firebase?

In simplest terms, this should work.... assuming you have no authentication rules setup (so data is read/write=true) say your data structure is like this: users <<top level project bucket |-167981 |-234:"hello" |-176584 |-123:"goodbye" |-158394 |-123:"goodmorning" |-167834 |-345:"goodevening" and you want to return the data associated with the tags 123. You need to go into the rules and set this: "users": { ".read": true,…

Hello, I think I found a different solution, I can simply add a "/" to create a subtag, thank you for your help.
