Details

Instructions for Reviewers

List of changes in this PR:

1. For Browse pages don't take into account sort configuration DSpace#8651: Updated browse-by-date-page.component.ts to set currentSort.direction with direction value from server and use them for subsequent requests
2. /browses endpoints return invalid _links based on the browseType value. DSpace#8879: Updated browse-response-parsing.service.ts to make use of new attribute _links.items_fieldValueOnly in order to ensure that any ValueListBrowseDefinition only request "/items" endpoint when there is a valid "filterValue" present.

Testing

After setting up DSpace server as in DSpace/DSpace#8871, go to angular page and:

1. Go to "/browse/dateissued" and verify that the results are sorted in descending order
2. Navigate to "/browse/author" ( All of DSpace -> By Author) and verify that there are no 500 requests for "/items" endpoints and no console errors logged
3. Navigate to "/browse/title" ( All of DSpace -> By Title) and verify that there are no console errors logged

Does this require the as-of-yet unmerged DSpace/DSpace#8871? I am seeing the HTTP 500 error that @tdonohue mentioned elsewhere, and the browse by pages don't work:

[buithaihai]

Yes, it is required, as stated.

[alanorth]

@buithaihai sorry, I didn't understand from your description that it was mandatory. Also, the linked pull request has feedback requested so I wasn't sure if it was in a working state. Apologies that I didn't get to test this for 7.6. I can try to test it for 7.6.1 though!

[buithaihai]

@alanorth No problem, it was already not ready for 7.6 anyways. Just take your time.
