Now an evolution of this app. How do I import list_pick items from firebase?

#11

for that you may know hoe to get data from firebase, if all data is in one tag, like a list stored in single tag, or all tags under one, simply get them store them in a variable and set that to list picker elements

#12

I can even store it manually in firebase, I don’t want to, but how do I display the data stored in list_pick?

#13

Excuse me. I expressed myself wrong. How to redeem the data stored in list_pick?

#14

for that you have to show how your data is stored in firebase, in single tag or in many tags

I am starting to work with Firebase and my database experience is very low. Today I can save data using some of Kodular’s logic blocks.

I can save a list of data in JSON format as I already use in the app, as in the image below. I just don’t know how to use this saved data as an imput in List_Pick?

set firebase bucket to “Movimentacao” (if its a main bucket no inner bucket of any other bucket, if its inner then use main bucket name/Movimentacao)
and call get tag list,
after tag list, set value to list picket elements,
and after selecting any selection,
set firebase bucket to Movimentacao/selection
and call get value Tag(Danilo), get value Tag(SVP-55)
after got value , if get tag is Danilo then set label(if you want to show data in label) to get value, else if get tag is SVP-55 then set label 2 to get value.

I will need two screens. One to register the data that will be posted on the second screen.

  1. Registration screen with two bucket:
  • Source
  • Destiny
  1. Launch screen with a bucket:
  • Movimentacao that will collect various fields from the APP, including Source and Destination. Like the example I showed in the database image.
    I will start as you suggested and tell you how it ended.

yes, give it a try, make sure that bucket inner bucket can be called by /, for example here,

if i need data from Tags, i have to set bucket Movement/Tags and then i can call get value from select or text.

#19

On the first screen, which I called “ENTRADAS”, I put two textbox and two firebase_batabase. I set both buckets as per the images below. How should I tag so I can use it on the next screen “MOVIMENTACAO”?

if you are storing data in that buckets then you can call from them, why storing in two different buckets?
