[EP-tech] Re: Cleaning database up

Hi David,

Try to do it in PERL using the EPrints API...

Since you're using 3.1.3 at Lincoln, the script will look like:


#!/usr/bin/perl -w -I/opt/eprints3/perl_lib

use strict;
use EPrints;
my $session = new EPrints::Session( 1, $ARGV[0] ) or die( "$0 repository_id" ); 

my $userds = $session->get_repository->get_dataset( 'user' );

$userds->map( $session, sub {

    my( undef, undef, $user ) = @_;

    ## do your own tests here on $user...
    # return if ...

    ## remove all eprints that are in the "inbox" (user area):
    # my $eprints = $user->get_eprints;
    # $eprints->map( sub {
    #
    #    my( undef, undef, $eprint ) = @_;
    #
    #    return if $eprint->get_value( 'eprint_status' ) ne 'inbox';
    #
    #    $eprint->remove();
    #
    # } );
## and delete the account if the user matches (not that this also removes the saved searches for that user) 
    # $user->remove();

} );

$session->terminate;
exit;
Note that I've commented out the bit that actually removes eprint/user objects - I let you customise it!
If I were you, I wouldn't remove the users that have some eprints in the repository - not sure how EPrints will cope will orphan objects. 

Seb.

Hi All,

at the current time the database that we have for EPrints is getting quite big with users that are no longer ever going to use the EPrints site again. I am looking at making a quick script which will go through the database and remove users if they have are no longer attached to an EPrint or they do not meet certain criteria i.e. join_date etc. I just wanted to quickly ask, how many different tables would I need to remove the user entry on or check for that matter to ensure its a clean deletion from the database. The current tables I know I will need to look at and clean is as followed:-

User table
eprints table
saved_search table

But is there any tool or method in /bin/epadmin for example which will clean the rest of the records if I do delete from the tables listed above. Any help or information you could supply would be of great helps, thanks all,

Kind regards,

David Whitehead.
