Alert Message column in Item Buckets

Note that the xul "Alert Message" field is available and should not be, the web client "Alerts" field is not available.

This adds a new column called Item Alerts to the copy buckets grid (regular grid and pending grid) that displays the 'note' for all alerts that are attached to that item.

(The brackets are a side effect of the fact that an item can have multiple alerts and I'm not sure how to make that prettier, but at least the data available.)

Which page should I be seeing your changes on? I'm applying the patch then I'm visiting Cataloging -> Item Buckets. Then I select a bucket. There's only 4 fields on the grid: name, call number, location, title

Let me know if I need to be checking some other page or if I need to do some extra steps before I see the new column.

You'll need to use the column picker to display the Item Alerts column.

Also, you'll need to add alerts to the items in the bucket (by editing them) in order to see anything in the column.

Testing this, I added item alerts to an item bucket columns. (alert messages choice doesn't have any display)

If no alert is on the item, [] (double square brackets display.
I then added alerts to some copies (see bucket #1). Alerts displayed as ["Test CONC70000337 "]
Items with 2 alerts display as ["Test CONC4100037 ","2nd alert message"]

When I deleted a message, in Holdings view, the count in the Alerts column didn't change (outside of the scope if this bug report, see https://bugs.launchpad.net/evergreen/+bug/1843087). In the item bucket, the deleted message still displays. See item CONC41000537 in bucket #1

Ah, so when you clear a message, it's not actually deleting it. Hmm.

Noting that the item status list view handles this nicely by showing the number of uncleared item alerts along with a button for managing those alerts that pops open a modal.

The uncleared item alert number is determined by filtering out the item alerts that have an acknowledgement stamp:

$scope.copy_alert_count = itemSvc.copy.copy_alerts().filter(function(aca) {
                return !aca.ack_time();
            }).length;

Deleted alert notes still display in item buckets in 3.8
