[EP-tech] Re: Restricting export of field based on value of another field



Hi John,
Not aware of a specific option as per your request - the thought occurs that it might be simplest to do something in eprints_automatic to move the abstract out to a new, different field that isn't on the exports when your flag is set, pulling it back to the abstract field when editing the item...  Perhaps an extra 'multi-value' field (although it only ever actualy has a 1:1 ratio with an eprint) so it exists in its own table, minimising any extra database storage requirement?

Subject: [EP-tech] Restricting export of field based on value of another field

Hi,
We have a requirement to (sometimes) embargo the abstract for some etheses.

We have a boolean field that allows a student to:
 - always show the abstract
 - embargo the abstract when files are embargoed

Changing the display of this information on the summary page is easy enough (change eprint_render.pl), but quite a few of the Export plugins reference the abstract field directly.

I could create copies of all the Export plugins that reference the abstract field, but this seems inefficient.

Is there a simple way of unsetting a field of a dataobject each time the dataobject is used, but without actually writing that change to the database?

Cheers,
John
