Hello, Bubblers.
I am working on a new application and suddenly got stuck on an easy at first sight task.
I have a datatype called “Commission” (2 fields “from” and “to” - all type “number”). Also there is a button for saving inputs mentioned above to the DB (create a new Commission).
Now I wan’t to add a check BEFORE saving a new Commission to the DB. I need to check whether there are any existing Commissions in the DB that intersect with a new one I’m trying to create. Intersection should be determined using a number range, where FROM is the minimal value of the range and TO is the maximum value of the range.
Example, I have 3 commissions in the DB:
FROM - TO
1 - 10
11 - 20
21 - 30
The check should work in the following way:
31 - 40 should be saved successfully (no intersections with existing commissions)
30 - 40 should not be saved (intersection with 1 commission from the DB)
9 - 32 should not be saved (intersection with 3 commissions from the DB)
Bubble has a data type just for this: Numeric Ranges. They have the same operators as Date Ranges, pretty much. Consult the Reference on number ranges and their operators.
Hi there, @artemzheg… I would approach this one by having one field (as opposed to separate FROM and TO fields) on the Commission datatype, and that single field has a field type of numeric range. Then, the workflow to create a commission would have an Only when condition that is configured like this…
Hey, @mikeloc and @keith. Thanks for pointing the direction!
I looked at Bubble Reference before, but was confused by locating numeric ranges description in “Slider Input” section.
Just replaced my two separate “number” fields with one “numeric range” - and it works, now it’s possible to perform any check with intersecting ranges!
Thanks!
Yeah, it’s a really interesting feature that I haven’t seen many people use (but it’s the same as date ranges, so anything anyone’s written about date ranges pretty much applies to numeric ranges as well.)
