Re: [EP-tech] How to remove a sub field from a compound field?

Hi Dennis,
Assuming you want to remove a sub-field from the eprint data object (dataobj) and you are running at least EPrints 3.3.x then you would need to edit the field in eprint_fields.pl under archives/ARCHIVE_NAME/cfg/cfg.d/ to remove the sub-field from the compound field*.  If you cannot find the field in here see if you can find the field somewhere else in the cfg.d/ directory.  If it is a compound field you will probably not need to remove this sub-field from cfg/workflows/eprint/default.xml but you may need to remove it from citations in cfg/citations/eprint/.
Generally, I advise against removing fields using epadmin remove_field, just in case you decide you want to reinstate it later, if you have remove it from all the places it is included (eprint_fields.pl, workflows and possibly citations and eprints_render.pl and other cfg.d files).  This should mean that EPrints forgets about the field and you shouldn't get any errors from EPrints trying to find a field that is no longer defined. 

Regards

*If you are trying to remove a sub-field for a core field on the data object you may not be able to do this by editing one of the config files.  Instead you will need to edit perl_lib/EPrints/DataObj/Eprint.pm or whatever data objects you are dealing with.

Hi,

Does anyone know how to remove a sub field from a compound field? I
removed the field from metafields.xml and metafields.pl. I also
removed any reference to it from other files in the archive cfg
folder, followed by a restart. This doesn't make the field disappear
however.

I tried epadmin remove_field on the subfield. This does delete the DB
table, but the sub field is still in the UI. If I run epadmin update
afterward, it just adds the table back.

Somehow somewhere it still remembers the sub field.

How can I completely remove the sub field?

Thanks!
