[EP-tech] Re: To make a field multiple afterwards

Hi Florian,

Recent versions of EPrints will do this for you as you run "epadmin
update" (added in May 2011).
The version we run is 3.3.10, hm. Is it necessary to do a reload before update? But then the system wouldn't have created the new tables at all.
The automatism perhaps isn't triggered on fields that consist of subfields. Maybe you might want to make sure there is an according test case? It seems so since the command created two tables: eprint_fieldname_subfield1 and eprint_fieldname_subfield2, can think of that scenario not being considered yet. 

Anyway, will have to make my hands dirty by altering it manually.

Thanks,
FH.

Hi,

in order to turn a single-value field into a multiple field, I do so by
adding multiple => 1 to the field definition in cfg.d/eprint_fields.pl,
then I do `bin/epadmin update $repoid`. This command will create the
additional tables. But how can I make EPrints transfer the data to the
new place, facing the tables still empty after that command? I wouldn't
enjoy much doing that manually, it's error-prone regarding the sub-fields.


Kind regards,
Florian Heß
