[EP-tech] Re: Issues following database change (possibly...)



I think Lizz is on the right lines (I'm guessing your 'eprint' dataset doesn't have a field called '1')!

What is 'Authorid.pm' - I can't see it on our system?
More specifically, what is on line 37 of it?

Also, for the views, you can run:
~/bin/generate_views 
 - try it with the --verbose flag (or the --verbose --verbose if that doesn't help).
This might give you some more insight as to what's not right.
If that seems to run OK, a graceful restart of Apache may help (I haven't played around with adding fields via the GUI - so this might not help in this situation).


With the Eprint stack trace, I normally read it from the top (displaying it in a non-wrapping window also helps!)

The start:
	[Wed Sep 03 14:06:14 2014] [error] [client 10.82.3.45] 
What went wrong:
	Can't use string ("") as an ARRAY ref while "strict refs" in use at /usr/share/eprints3/perl_lib/EPrints/MetaField/Authorid.pm line 37.
	Use of uninitialized value in string ne at (eval 105) line 31.
	dataset eprint has no field: 1
	------------------------------------------------------------------
	---------------- EPrints System Error ----------------------------
	------------------------------------------------------------------
	Attempt to get value from not existent field: eprint/1
	------------------------------------------------------------------
	 at /usr/share/eprints3/perl_lib/EPrints/DataObj.pm line 702.
The rest of the stack trace may be useful to see how the lines of code above were invoked.

Cheers,
John

This seems to be the most prevalent error, but it?s not clear to me where
the issue lies:
