[EP-tech] Re: Adding fields to admin search

Hi,
Good question. One I didn’t know the answer to until I had a quick look.

This is my thought process:
1. Log in to EPrints, go to the admin search page.
2. Look at the URL. It ends with screen=Staff%3A%3AEPrintSearch
3. Mentally convert the screen parameter above to a file to look at - resulting in: ~/perl_lib/EPrints/Plugin/Screen/Staff/EPrintSearch.pm.
4. See what search config it uses [search->advanced->search_fields] AND something a bit *magic* looking 'extra_fields' (sounds like exactly what we need :o).
5. Grep rest of EPrints code to find other mentions of 'extra_fields'.
6. Be disappointed.
7. Look at: http://wiki.eprints.org/w/API:EPrints/Plugin#param
8. Think that adding:
$c->{plugins}->{"Screen::Staff::EPrintSearch"}->{params}->{extra_fields} = ...SOMETHING...;
is the way forward, SOMETHING being some config similar to the existing search config options.
9. Decide to leave the next step for you, with the hope you add the recipe to the 'How To' section of the wiki: http://wiki.eprints.org/w/Category:Howto
10. Lunch! Sunshine!
11. Actually, I'm interested. What should that SOMETHING be..?
12. Add this to a file in ~/archives/cfg/cfg.d/ (possibly the eprint_search_advanced.pl, or plugins.pl, or some other file that you'll be able to find it in again!):
########
#Additional field for internal staff search
########
$c->{plugins}->{"Screen::Staff::EPrintSearch"}->{params}->{extra_fields} = [
                { meta_fields => [ "id_number" ] },
                { meta_fields => [ "documents.license" ] },
];

NB: This is based on 3.3.10.

Cheers,
John

Subject: [EP-tech] Adding fields to admin search

Hello!

I’ve now been asked to add some fields to the admin search screen in EPrints. I’ve found a snippet here: http://trac.eprints.org/eprints/ticket/3637 which suggests how different fields can be added in, however the function in question is different in the version of EPrints we are running. So, any thoughts on how we can do this? The Trac page suggests that this was put forward to be added to a future version of EPrints as an admin function, however I presume this has yet to happen?
