[EP-tech] Re: IRStats installation problem -- how to update

[Jon.Hallett at uwe.ac.uk (Jon Hallett)]

Hi Alex,

The trick is that that code snippet has to be added to eprint_render.pl at a very specific place to ensure that $links has already been declared. If you have a look at eprint_render.pl, you should see these lines near the bottom:

        my $links = $session->make_doc_fragment();
        $links->appendChild( $session->plugin( "Export::Simple" )->dataobj_to_html_header( $eprint ) );
        $links->appendChild( $session->plugin( "Export::DC" )->dataobj_to_html_header( $eprint ) );

Add that code snippet immediately after those and you should be good.

Thanks,

Hi,

I am using EPrints 3.2.8 (Apple Crumble).

In the installation instructions for IRStats, it says:

5 Integrating IRStats (optional)
----------------------------------

i) Add IRStats download graphs to individual item summary pages

Add the following to archives/ARCHIVEID/cfg/cfg.d/eprint_render.pl:

        if( !$preview )
        {
                # IRSTATS CODE STARTS HERE
                if ($session->get_repository->can_call('irstats_abstract_content'))
                {
                        $page->appendChild($session->get_repository->call('irstats_abstract_content', $session, $eprint));
                }
                # END IRSTATS
                $links->appendChild( $session->plugin( "Export::Simple" )->dataobj_to_html_header( $eprint ) );
                $links->appendChild( $session->plugin( "Export::DC" )->dataobj_to_html_header( $eprint ) );
        }

        return( $page, $title, $links );

To enable, run the following command and then restart apache:

 $ cd /opt/eprints3
 $ bin/epadmin refresh_abstracts ARCHIVEID
__
But the output from bin/epadmin refresh_abstracts ARCHIVEID is as follows:

eprints at zeprints:~/bin$ ./epadmin refresh_abstracts mdxrep1
------------------------------------------------------------------

Any suggestions on how to resolve this issue most gratefully received.

Thank you.
