Prevent old database items from still displaying

Hey Bubblers!

I have a question on how to remove a thing from a list of things only when the value was changed.

It should be easy enough, and I feel I’m missing something simple here.

So I would like to do something like
‘My List remove Thing’ Only when: a change was made to this field
(because I have multiple inputs that could be updated with the same Save button in one workflow)

I try to show and explain in this video: https://www.loom.com/share/7cd58dccb20c4ce6aa4d6c948482898b

If anyone could point me in the right direction, that’d be awesome!

Hi Johanna,

Nice looking app!

I suggest you reconsider using a text as a pair … and actually create a data type called pair with a field called title (or however you wish) of type text.

Why?

A user may input the same text twice and it will mess up things in your app. If a pair is not a text but rather a dB object (in Bubblish … a “data type”) it can have its own unique id, it can have a date when it was created, it can have a user who created, and any other metadata or relation that you may need for such a sophisticated app that you are building.

As for the concept of adding or substracting entries from a list, I suggest the following videos which are very instructive:

Hope this helps and best of luck with your app!

Thanks @cmarchan, that makes perfect sense, I’ll definitely try that! Sounds just like the easy answer I was hoping for, but couldn’t see. (So easy to get lost in Bubble after a long work day!)

Appreciate you taking the time to reply, and glad you like my app
