Multiple database request

[giovanny_padilla]

Hello all,

When I preview my app, I see that lot of requests. The last time I was working on it, this was not happening.

I know the response come from the database for the dynamic items logic handlers. In the past, I tried to change the logic to request the database just when the page enters but, it seems to me that this is not the intended behavior.

Can you send me to the right direction?

Hello @giovanny_padilla

The Dynamic Items Logic runs on each render that’s why you can see lots of requests

Take a look at the following answer :

UI Builder page data inconvenience

I see The main issue is your logic requests data from the SavingRecords table on each render, is that what are you worrying about? The Dynamic Items Logic handler is designed for assigning a list of already loaded data, and it runs each time when above data is changed, so this is not a good place to request data here. Instead you can load the data in the On Before Mount handler which runs only once

Ok, thanks. So request the database just once in other handler and then load the dynamic list from the app data or page data.

correct, also you can make any Block as DataContainer and it will have its own DataModel where you set data and then use it in the list
