Re: [EP-tech] Error on New Metadata Field

Hi Izwan,

I have been able to reproduce this bug but I cannot quite understand why this would lead to an error as it calls a function that is not called by other subject fields.  I will need to dig a little deeper to get to the bottom of this. I would not be surprised if this is a rather long standing bug as usually MetaFields are added from the command line and the occasional times MetaFields are added via the web interface, Subject MetaFields are an unusual type to add.

Regards

David Newman

Hi Izwan,

I suspect the issue is that the parent subject with the ID 'journal' does not exist.  Click on the Admin link in your menu and in then "Config. Tools" tab on the Admin page click on the "Edit subject" button.  You will need to create a 'journal' subject.  You can do this by adding the word 'journal' in the input box next to "Subject ID String" and then clicking on the "Create" button.  You will then need assign a label for this subject (e.g. Journals) and set whether it should be depositable (probably not, as this is a parent subject).  You will then need to add subjects under this parent 'journal' subject for all the journals you want a user to be able to choose from for this 'journal_in_university' field.  I would try to use a consistent format for these journal subject IDs like jrnl_nature for the Nature journal.
