Add list to tiny db without deleting previous value

Hi all
How to append list items into tinyDB ,without deleting the previous values
for example when i store to tinyDB a new list of items , tinyDB clears the previous values and add the new list . what happens is that …
first time i open the app and select an item to save to DB and make a list of it and it goes ok , when i close the app and open it again the list also is ok , but when i add new list items to DB i found the last items i added only appear ,not all items i added

this in screen 1

and the the new items to be saved in screen 2

any help for this ?!

Hi, Moustafa.
You can’t add data to TinyDB ( last data store are there ). But can store TinyDB data into in a variable and add data to variable and last store this into TinyDB. I hope that it should be understood what I mean.

More easy:
If you store on tag “user” the values 1, 2, 3 and next store on the same tag the values 4, 5, 6. When you get TinyDB value of tag “user” you get only 4, 5, 6.

Well, this way will be better bc of the less kode if it works. But I don’t excoriate you, I thought of yours, too :kissing_heart:

thank you Leandro i got it , thanks for your time :heart_eyes:

thank you yoshi for your time i used it but in the next time i open the app i see that it make a list of all items in the first item (a list in one item) and add the new in second or third so i found the solution with
@WatermelonIce

I see the problem.
As @m0ustafamahm0ud said

If the user continues storing more list, it will make a list in a list in a list in a list… and so on

Oh yes, it is my problem. :slight_smile:

no no no you are the best :heart_eyes:

Thanks :grin:

Btw, because you cannot define a variable as tinyDB GetValue, so you have to set it to an empty list first, then when screen initialize set variable as tinyDB getValue

I found that this solution is the same as mine, but @bestprintsf is first, so you may mark his answer as the solution.
