Dropdown Filter sometimes does not populated

Get Help

Here is everything i see in the JSON object minus the fields with sensitive info 24%20PM13%20PM01%20PM

@BrettJohnson
Pretty sure you’re not looking at the /api/field/X request.
The /api/field/X/values request will not have any meta data, but just the values for the dropdown.

23

Yeah that is not the field api request, that is the JSON object that i posted earlier. I will get those field requests once i get it to work. The reason i believe it to be a caching or syncing issue is the dropdowns seem to be working every 30 mins or so then they stop working after a minute or so.

@BrettJohnson
But if it has something to do with sync, then check your sync settings. And you should see something in the logs.

Here’s what one of my dashboards with a single filter gives me:

@BrettJohnson
You might want to dig around in the internal Metabase database - hopefully you’re not using H2.
You’ll most likely find something in the table metabase_fieldvalues - but there are a lot of tables, which could have interesting data concerning this issue.

27

Here is the JSON object for the values request 04%20PM

28

@BrettJohnson
That’s the field meta request - the values are coming in a second request. But the field meta looks fine, so I’m guessing the dropdown works in that case.
You have to monitor/test and see what happens, when the dropdown doesn’t work.

Hey!

The last reply to this topic was almost 2 years ago but let me try my luck and see whether someone answers. :grin:

I read through the whole thread and following questions remain:

1. How can we obtain updated field filter values in the Metabase database?
If I look into the JSON object (see therefore example below), I see that the key value pair “updated_at” is not updated to the most recent date.

[
{
“id”: 1234,
“created_at”: “2020-10-14 15:05:10.353556”,
“updated_at”: “2020-11-03 14:51:25.665458”,
“values”: “[“a”,“b”,“t”,“i”,“m”]”,
“human_readable_values”: null,
“field_id”: 29012
}
]

2. What exactly happens in the backend when Metabase collects the list of values for a dashboard drop down filter?
E.g. does it perform an UNION in a query in the background? How does Metabase know what it should display to the user?

Your support is highly appreciated! Thanks in advance! :blush:

@matrioschka That is handled by the daily scan:
https://www.metabase.com/docs/latest/administration-guide/01-managing-databases.html#database-sync-and-analysis
There’s an issue in the 0.37, which causes a query when showing the dropdown:

Thanks so much!!
Helped me really a lot. Highly appreciated. :slight_smile:
