Fix/comments bug

[Mxchaeltrxn]

Addresses #304

Changes made
Frontend

• Change 'Reply' to 'Comment in Thread'.
• Add 'Delete' and 'Block User' button to thread comments.
• Update 'Delete' button pop up for thread comments.
• Number of comments decreases immediately when you delete a comment (not sure if this is possible).
• Hide the 'Block User' button for a user's own comments.

Backend

• Delete thread comment functionality.
• Setting blocked users.

Bugs noted:

1. When a user is blocked, it's not possible to unblock them. There's some code that sets isBlocked in generateCommentsObjects.js but it has been commented out. I didn't want to fix this because I'm not sure what the deal is with the commented code.
2. Should line 731 in internalApi.js be

// Note the '||' instead of '&&'
function deleteComment() {
    ...
    if(!userIsUploader || !userIsCommenter){
      throw new Error('not the proper user');
    }
    ...
}

I've updated the threadComment variable to be called commentInThread in my latest commit @mayeaux

In regards to:

Number of comments decreases immediately

There are Node.removeChild() and ChildNode.remove() methods which allow to nuke DOM nodes and rerender the tree. Ofc it should wait for the server response before the actual removal.

So it would go like this:

• user pushes the delete button
• all relevant validation checks go through
• the server returns a response
• node removal is ran in case of successful response

As for

Hide the 'Block User' button for a user's own comments.

Wouldn't an _id comparison between the person deleting the comment and the _id of the comment suffice for that? Though sending _id to the front is kinda sketchy to begin with, but that's what the code does.

Also use the unbuffered comments please.

@BassOfBass Thanks for the comment.

I'm not too familiar with server side rendering but the number of comments is a variable (commentCount) that gets passed into the pug template from the backend. It doesn't seem to change even when I remove the node. Only a page refresh seems to work (e.g. location.reload()) which is not ideal because it brings the user back to the top of the page.

The block user functionality is there but commented so I'm not sure what I should be doing with the commented code.

I'll use unbuffered comments after your pr gets merged. That way, it'll be easy for me to know which buffered comments are mine

I'm not too familiar with server side rendering but the number of comments is a variable (commentCount) that gets passed into the pug template from the backend.

That's because media.pug is a big mess. A ton of inline <script> inserts (a lot of them are done through partials too, so it's even harder to get a hang of) and even more global variables inserted through them.

commentCount is just a number, you can't rely on it for DOM manipulation. comments is the one you'd need, though if it isn't stored, you'll have to collect them off the page in a NodeList.

There are 3 files responsible for comment section:

• controllers/frontend/mediaPlayer.js
• lib/mediaPlayer/generateCommentsObjects.js
• views/media.pug

/api/comment/delete is the end-point responsible for comment deletion, which invokes deleteComment() method.
It looks like the route already performs all needed auth checks, so you only need to fetch() a "POST" response to it as a result of pressing the button and, depending on the outcome, either remove the comment from the the page or return an error.

The main hurdle there is you'll also need to surgically remove related jQuery logic, which is all over the place.

Thanks for the detailed breakdown.

I will leave it for now because it just seems too complicated for me to handle right now but this information will be useful for anyone who decides to implement it in the future anyway.
