Hello, sorry for my bad english 
I am creating a car rental application and I find ADALO great !!!
However, I am stuck on one point, if an angel can help me lol
I would like to block the fact that we can rent the same vehicle on the same dates.
For example, vehicle “A” is rented from 10/06 to 12/06 and when I enter a new rental date I would like vehicle “A” not to be available in my picker date.
I put a column “disponibility” in boolean in my database but I can’t …
And I can’t find the custom action, I see that the “always” or “sometimes”.
Thanks in advance to the community;)
Hi, I have the same problem, but is with a booking system for hotel. Did you get?
There are 2 ways to do this.
You can set a conditional action that is based on a filter if that date/time is already booked, that you could link to a screen that displays a message for that.
Or you can set a visibility rule on the list item to only display if that item is not booked at that date/time.
Just seen this thread,
