Firebase data replacement issue instead of adding

Friends, when I try to load data in firebase, I do not want it to delete the data, I want it to add other data in the same list, how can I do this.

Use append block

I add it but it doesn’t work it gives an error

Show your relevant blocks.

I get this error

exactly like this

No this is wrong way. First you need to get the existing value from the firebase into a vatiable which is initialise with emoty list, then add iyems into this list then append the value into firebaselist

I don’t know how to do it, but can you show me with an example block?

Show your fb structure

Let me tell you the order I want to do, I created a user registration section, he wants to take the id of the users and save the photos they have taken as a link to the cloudinary and print the links next to the id of the users.

This is not called append…

Use the bucket as UsersPhoto
Store firebase value tag (user id)
Value (url)

So your fb struture will look like


mine looks like this

Yes, this is not called append… This struture only i have mentioned above and that one is good to use

Append mean

User id - value1,value2,value3…

And so on

well, is there no way to sort the links by the ids of such users?

Are you looking this option to be add in admin app? Want to sort users orderly?

My purpose is to print the url of the photos sent by that user from cloudinary next to the user’s name after registration.

So you want all the images sent by user in a list wait. Let me show you

Could you please show me

try like this


fb struture

while appending the values must be in list

In your case try like this

unfortunately, i tried and it still gives list error
