Cannot filter Data Grid by computed If-Then-Else column (current month)

Hi,

I have a table called “Koledar” with a proper Date column.

I also created a computed column:

  • is_tekoci_mesec (If → Then → Else)
    This column returns true when the row date is in the current month.

Problem:
When I try to filter a Data Grid, Glide does not allow selecting
the computed column (If-Then-Else) in the Filter Data options.

I understand that computed columns might not be filterable,
but I want to confirm the best practice.

Questions:

  1. Is it correct that Data Grid filters only work with basic (non-computed) columns?
  2. Is the recommended approach to always filter directly by the Date column
    using “date is in This month”?
  3. Is there any supported way to use a computed boolean for filtering,
    without copying its value into a physical column?

Thanks!

Sounds like you’re using a Big Tables for the relevant table here. Can you confirm?

Yes, i use big tables.
