I was wondering if anyone had a best practice for tracking which notifications have been read.
Let's assume you have a bubble at the top with the number of unread notifications, like on Facebook.
Currently ABP supports subscribe / publish. But I can't find anywhere automatically built in for tracking which notifications have been read and which haven't.
Anyone do this with ABP's notification framework yet?
I'm thinking I add my own table ReadNotifications with the following columns:
Id UserId NotificationsId CreationTime
Then I only add a row to this table once a notification has been read for this user. If a notification Id along with the user Id does not appear in this table, then you can assume it was not read.
I feel like that is not the best way though? Is it a table scan every time you need to check if each notification was read or not? Could get really slow.
My other idea to add a column to the AbpUsers table:
UnreadNotificationsIds
Then comma separate the notification ids that have not been read there. But I feel this is also not clean? This would be faster than the first approach probably.
Looking for your thoughts.
Thanks!

Hi,
As my little knowledge of abp -zero, it's already have a table for this stuff,
SELECT * FROM [dbo].[AbpUserNotifications]
You can use State column which has two values: 0 and 1 correspoding with UserNotificationSate enum of abp framework

Use IUserNotificationManager for it (<a class="postlink" href="http://www.aspnetboilerplate.com/Pages/Documents/Notification-System#user-notification-manager">http://www.aspnetboilerplate.com/Pages/ ... on-manager</a>)
