Typo3 8.7.32 - Columns in custom extbase tables become partially "broken" every once in a while, does anyone look similar?

Question

I developed an extbase plugin that imports data from an external API into our website. The plugin depends on external_import, svconnector and svconnector_csv.

Everything works fine and has been working for several months, but on rare occasions (once a month or less) the data from a single column is converted to random numbers, but some are fine. It's always the same column of the same table. I looked it up and the numbers don't correspond to anything in the API.

There is no trace of these headers turning into numbers in sys_history, sys_log and tx_externalimport_domain_model_log, but when I re-import the data from the api, I have them Restore normal history. Also, when they move to numbers, tstamp doesn't update (yesterday (August 18th) was not a number, 165694181 corresponds to July 4th).

If anyone knows what might be happening, thanks!

Answer 1

You might use option sortby.

'ctrl' => [
    'sortby' => 'your_field',
],

Normally TYPO3 uses a field named sorting for this.

TYPO3 From time to time records need to be reordered, so the sorting columns are renumbered. Any previous information is gone and a new set of indices (numbers with distances so that new records can be inserted in between) is inserted.

If you only want to display data sorted by other fields, use option default_sortby:

'ctrl' => [
    'default_sortby' => 'your_field',
],

And delete the value of sortby.
