We register tasks in LabelStudio as json files via the python SDK. When registering the task we make use of the data object within the task description, to add kind of meta data to the task that is relevant, see here:
{
"id": 25132,
"data": {
"csv": "/tasks/25132/presign/?fileuri=YXpJvY2Vzc2VkLmNzdg==",
"m_process_end": "2025-03-19 23:18:35.065000+00:00",
"BMMC.ACT.O1.QCMS_Frequency": 5960674
},
"annotations": [],
"predictions": []
}
As you can see above, the data field m_process_end is a time stamp. What we would like to achieve is, that you can filter in the task overview on that column via a time filter. Comparable to what you can do on the pre-built columns like Created at .We only achieve to filter on that column like on a text field, for example via regex, see here:
Note that for Created at you have options like “is before” but for m_process_end you only have classical text filters.
It makes sense in way, as we register “m_process_end” as type string, but we could not figure out how to change to datetime type or similar.
Is there any way to achieve this?
