I am using the TYPO3 extension feupload, which relies on extbase. This is my first contact with extbase.
But the question is about extbase in general.

I expect TYPO3 to include the usual "IN (current-page)" pid check by default in queries, unless told otherwise - but in extbase that seems to be different. Or at least in my case, it's not working.

In the extension, there is a constants / setup setting, where the storagePid can be set. This works.
But we don't want to adapt that parameter manually for each page.

```
persistence {
       # cat=feupload/persistence; type=integer; label=Storage PID of records
       storagePid =
}

```

So how do I make extbase get the PID of the current page automatically as expected?

(Sub-question: I've tried to set plugin.tx\_pluginname.persistence.storagePid.data = {page:uid} in setup, but that wouldn't work. What would the TS have to look like to work?)
