Technical Help : filter date_before ?


When I try to filter with : “date_before” it doesn’t work.
I tried with the following two formats:

Can you help me apply this filter ?

Thank you in advance for your help.


This looks like a classic mistake where single and double underscores are not used correctly. A mistake I make myself very often.

So, the correct syntax would be filter__field_1302403__date_before=2023-09-29

Filters always use this syntax: filter [double underscore] field [single underscore] [id of the field] [double underscore] [name of the filter]

I know it can be confusing from time to time.
