Re: [EP-tech] Modifying Details.pm/Overwriting module

Hi John,

Ahhh this would have been ideal. I did try searching for "overwrite EPrints plugin" and couldn't find anything. I'll give this a read and try to apply it.

You are correct; it was the render function that had to be altered. Our repository team have a select few fields that they need to check that are near the bottom of the details screen so it was my task to duplicate a few fields at the top of the page.

Thanks,
James

Hi James,

This handy guide might help too:

https://wiki.eprints.org/w/Instructions_for_local_plugins

 

From your original email it sounds like you want to change a small part of 'Details' - maybe just the 'render' method.

Following the instructions on the page above, you'll basically sub-class the EPrints::Plugin::Screen::EPrint::Details to EPrints::Plugin::Screen::EPrint::MyDetails.

In the MyDetails file, you can then specify your new render method, and then do the 'plugin alias' - and you're there.

 

Cheers,

John

James,

Have a look at plugins.pl in cfg.d , specifically the section starting at line 46 : https://github.com/eprints/eprints/blob/3.3/lib/defaultcfg/cfg.d/plugins.pl#L46

 

This shows how to tell eprints to replace the existing function with the new one, and not create duplicates or fill your server log with ‘redefined’ warnings.

Apologies, ignore the previous email. I think I've done it.

 

It seems if I put the file in the suitable archive location and keep this line the same:

 

package EPrints::Plugin::Screen::EPrint::Details;

 

If I change the file name to something different (e.g. Detailz.pm) it appears to overwrite the original Details.pm.

 

Previously I was changing both the package name and the filename and it was including both.

 

Thanks,

James

Hi All,

 

Could somebody please tell me how to overwrite an existing Perl module in EPrints?

 

I recently made some changes to Details.pm. I know better than to modify it in-situ, so I took a copy and moved it to my specific EPrint archive.

 

Original:

eprints3/perl_lib/EPrints/Plugin/Screen/EPrint/Details.pm

 

New edited version:

eprints3/archives/uolrepo/cfg/plugins/EPrints/Plugin/Screen/EPrint/Details.pm

 

EPrints didn't pick up my changes (even after a server restart) unless I named the edited module something different so I called it:

 

Detailz.pm (package EPrints::Plugin::Screen::EPrint::Detailz;)

 

I've made the changes to how the page renders, but my problem now is I have a "Details" and "Details2" tab on the staff view of an EPrint. I want only my new Details.pm module to be brought in. I did follow Adam Field's YouTube video that touched on this, but it wasn't quite the same problem and didn't work.

 

Thanks,

James
