Re: [EP-tech] Search form

Hi Lessard,


We implemented our system a little differently that Gilles did with Cirad.


We re-used the original creator_id field, and update its contents as the author records get manipulated.  We also wrote custom view render logic for the double hop we make, from creator->author_instance_id->author_id, so our browse by author view (http://eprints.usq.edu.au/view/uniqueauthor/)  is listing the Unique Authors by name, then any cited name used.  Virtual Fields would likely streamline this process a bit more…


There are Training Video’s on the eprints wiki, https://wiki.eprints.org/w/Category:Training_Video


The one I think would suit this application is the Virtual Fields video (https://wiki.eprints.org/w/Training_Video:Virtual_Fields). 

From the description…


“Virtual Meta Fields are fields that are not stored in the database, instead

their input and output is programmed. They can be used whenever a default

display-value is not suitable. Since their value is calculated their uses are

limited by one's imagination.”


So you could create a virtual field, that handles all the linkages between datasets, and provides a single point of data for your search screen.


I think I have the process correct in my head, but I am happy for anyone (John, Ian, Adam) to point out any problems with understanding J
