Angular staff catalog facets are effectively hard-coded

Evergreen version: 3.6+
OpenSRF version: all
PG version: all

The public catalog templates allow an administrator to define the set and order of facets that could be displayed for any search result. The Angular staff catalog follows the same logic but does not have a way for an admin to specify the facet display configuration except by adjusting code and recompiling the Angular client.

Bill Erickson has put together a WIP branch to help address the more general problem of Angular catalog config and customization here:

  https://git.evergreen-ils.org/?p=working/Evergreen.git;a=shortlog;h=refs/heads/user/berick/lpxxx-angular-dynamic-config

His branch addresses the specific concern of this bug but demonstrates a general framework for attacking (some of) this class of problems. Feedback (on the problem, and his branch) sought!

And as a first bit of feedback, I think it would be useful to have this file live in the opac template area near config.tt2 so that it can make use of the existing (public catalog) template override functionality.

In an attempt to be the change you want to see in the world, I offer the branch at https://git.evergreen-ils.org/?p=working/Evergreen.git;a=shortlog;h=refs/heads/user/miker/lp-1932350-angular-dynamic-config that extends Bill's patch by making the Angular dynamic content file into a template, so that it can be used in the same way as config.tt2, per hostname, and allow various settings within a consortium.

Hi Mike, I loaded this to try it out and it looks like something's off. I'm getting a 404 for angular-config.js which kills the Angular catalog completely. My gateway logs have entries like AH00128: File does not exist: /openils/var/web/eg/eg2import/angular-config.js, referer: ... so it looks like the template processor isn't picking it up?

[Galen Charlton (gmc)]

Looks like the LocationMatch around line 766 of eg_vhost_24.conf is what's getting in the way.

This patch should get the Apache side of things working.

Tested on Equinox community server, demo.evergreencatalog.com, on Release 3.11.1 and there is still no More option in facets, so we can only see the first five.

The issue of how many links are shown is covered in bug 1934018 (which has a branch); this one has to do with rearranging the Author, Topic, Genre, etc. boxes in the staff sidebar or showing different boxes altogether.

[Chrisy Schroth (cschroth)]

It seems as though this has been fixed. Our 3-11-7 catalog has had More links for the Staff Catalog facets in the Angular search when warranted for a while (we just noticed one day that they were there). I just checked on the Bug Squashing Week MOBIUS Test Server 1 to make sure and there are More links for Personal Author, Topic Subject, and Series Title. I don't think the other facets on my search have any more to show.

[Stephanie Leary (stephanieleary)]

The More links have been added, but it's still not possible to rearrange the facets. In facets.component.ts, there's a hard-coded list at the top:

display: [
        {facetClass : 'author', facetOrder : ['personal', 'corporate']},
        {facetClass : 'subject', facetOrder : ['topic']},
        {facetClass : 'identifier', facetOrder : ['genre']},
        {facetClass : 'series', facetOrder : ['seriestitle']},
        {facetClass : 'subject', facetOrder : ['name', 'geographic']}
    ]

I've been playing around (in my copious spare time) with some ways to turn this into a drag-and-drop interface. Several rabbit holes later, the Dragula library for Angular (https://valor-software.com/ng2-dragula/) looks like a possible replacement for several of our manually-created drag-and-drop functions.

That's as far as I've gotten without a formal project to work on this.
