[$300] Update UI: Watching feature

[Oanh-and-only-Oanh]

Expected behavior:
PUBLIC FORUMS

1. If user is "watching" a parents category, the eye ball should be turned on for all sub-threads in that parents category
2. If user turns off the "watch" feature on any sub-thread, the eyeball icon should be turned off on the parent category
3. Add "watch" eyeball icon on the parent level next to title. See screenshot below

@atelomycterus - Please see above and let me know your thoughts

My initial concerns relayed to the team were:

The problem is that, if a user has a watch on the main category, they do not have watches on each individual thread - that's implicit.
So, if the user un-watches a thread, we have to:

• Unwatch the category
• Watch every thread explicitly
• Remove the watch for the single thread that was unclicked

And, if the user chooses to watch the whole category again, we have to:

• Unwatch every thread
• Add the watch to the category

Not a big deal, but I just wanted to point out that this is a little more complex than it may appear on the surface.

The other side effect that we have to think about is what happens if a user turns the watch off for a parent category and a new thread is added? Do we watch that thread by default or no?

@atelomycterus - Any thoughts on this one? Is there any way we can have a category level watch but ignore specific discussions underneath that category watch?

@jmgasper I keep in mind, but did not want to rush to this task.

From the screen above User is watching New Here & Getting Started category.

DB

Watching a category: data are stored in UserMeta table. 4 records should be inserted per a watched category:

Preferences.Email.NewComment.CATEGORY_ID
Preferences.Email.NewDiscussion.CATEGORY_ID
Preferences.Popup.NewComment.CATEGORY_ID
Preferences.Popup.NewDiscussion.CATEGORY_ID

Watching a category (discussions type)

Example, User is watching New Here & Getting Started category.

1. If user is "watching" a parents category, the eye ball should be turned on for all sub-threads in that parents category

Ok, we can show the green eye ball.

2. If user turns off the "watch" feature on any sub-thread, the eyeball icon should be turned off on the parent category

• Unwatch the category
  Yes, remove data from UserMeta table.

• Watch every thread explicitly

• Remove the watch for the single thread that was unclicked

Yes, need to get all discussion IDs in CategoryID except unclicked discussionID and insert XXX records with Bookmaked flag (1) in UserDiscusssion table.

And, if the user chooses to watch the whole category again, we have to:

• Unwatch every thread
  For consistency, it'd better to set Bookmarked flag = 0 for all discsussion with this categoryID in UserDiscussion table.
• Add the watch to the category
  Yes, insert data into UserMeta table.

The other side effect that we have to think about is what happens if a user turns the watch off for a parent category and a new thread is added?
Do we watch that thread by default or no?

No notifications if a new thread is added or a new comment is added for previously created threads.

I think a small change will help simplify it and we can meet the requirements.

1. If user is "watching" a parents category, the eye ball should be turned on for all sub-threads in that parents category.

2. If user turns off the "watch" feature on any sub-thread, the eyeball icon IS NOT changed on the parent category.
   We don't remove data from UserMeta table. So user can receive notifications if a new thread is added or new comment is added for other threads.

Show the grey eye ball icon for an unwatched sub-thread only.

We add only one record in UserDiscussion with Bookmaked flag = 0. Bookmaked column has existed in UserDiscussion.
So we don't need to insert a bunch of new records in UserDiscussion.

Need to fix Vanilla notifications if user watches a category and new comments are added to unwatched thread then don't send any notifications.

If user turns on the "watch" feature on this sub-thread again. We need to update Bookmaked flag = 1.

3.Add "watch" eyeball icon on the parent level next to title. See screenshot below

Ok

Let me know your feedback. Thanks!

Watching a category (nested type)

Example, Watching General category, the parent of New Here & Getting Started category
It's more complicated case. Let's me know if this is in the scope.

@atelomycterus - This is great information, thanks, and in-line with what I was hoping we'd be able to do. Let's skip watching the root category, like General for now - we can figure that out later.
