Transcript
00:00
We're pretty much going to repeat what we just did in the last episode,
00:03
but this time we're going to delete entire discussions. And once again, our database should handle this by removing all posts that are part of them discussions. And before we do that, I'm just going to create a
00:14
another discussion out here called Delete Me, just so we've got something to play around with. And let's choose a topic here, start this discussion, and we're going to delete this entire discussion.
00:26
So once again, we're going to need authorization. That's a really, really important part of this here. So we're going to head over to the discussion policy, and we're going to go ahead and just duplicate one of these down
00:36
and say, delete or destroy. And we will get a user in here. We will get a discussion in here. And once again, the condition here is the same. We just need to be able to, or we just need to actually own this discussion.
00:49
So let's say that the user ID equals the discussion's user ID. OK, so now that we've done that, we can head over to the discussion resource and we can add this in here. So really, we're just repeating what we've already done here.
01:04
OK, so now that we've done that, we can head over to the show page where we are outputting the title of the discussion just here, and we can go ahead and show this button next to it. So let's, well, that's the topic title.
01:19
There's the discussion title. So let's go ahead and add this just into here. In fact, we'll do this outside of the H1. And we're going to create an unordered list
01:27
because we might have some other options in here later. And let's put an if statement on this. And we know that this is whether the discussion user can delete. And in here, let's go ahead and create out a button.
01:43
And we'll say delete here. And let's just see if that shows for now. And it does. If we head over to a discussion that we didn't start,
01:50
so I think this one maybe, of course, we don't see the button. So as long as we own that discussion, we're all good. And we're now showing that button now. So let's go ahead and just add some classes on this.
02:00
So we'll pretty much do what we did with the buttons within the post and set the text to small. That should just be about it. Great.
02:10
OK, so what are we going to do when we click on this? Well, pretty much what we did within our post. We just want to call some sort of method to go ahead and handle this directly with the NERSH's router.
02:19
So let's call this delete discussion. And let's come to our script section. And let's go down just to the bottom here. Create this out real quick.
02:29
And we're just going to post through. Of course, we don't have anywhere to go through to yet. So let's go ahead and create out our route and our controller. So again, just following the same pattern,
02:39
we're going to go ahead and make out a discussion destroy controller. And let's head over to our web routes and create our route for this. So let's copy this one here. We'll say delete, deleting that discussion in here.
02:55
And discussion destroy controller. And we'll say discussion and destroy. Let's make sure we're keeping the same names here. That's fine.
03:07
OK, so over to the discussion destroy controller. Once again, we're going to go ahead and create out a form request immediately for this. So let's go ahead and make one out now.
03:16
Make request. And that is, of course, going to be discussion destroy request. Let's add that directly into here. And we should be good.
03:30
Let's add that into the request. And let's say discussion in here. And there we go. So let's make sure we just pull the namespace in for that.
03:39
And again, we're just going to do the same thing. Discussion, delete, and then return back. And that's pretty much it. Now, we aren't actually going to return back.
03:47
So we do need to change this around. Because, of course, we can't return back to the discussion that has been deleted. So in this case, let's go ahead and say redirect route. And let's see what we called our home page.
04:03
Probably just home. Yeah, probably best to just jump straight over to the home page. OK, so over in the discussion destroy request, let's go ahead and authorize this. So auth user can delete.
04:17
And again, this discussion. So exactly like what we did with our posts. And we should be good. So let's just go and hook this up on the client side and see if this works.
04:29
So I don't think we have our router pulled in here. No, we don't. So let's go and pull this in first of all. And then if we head down, let's go ahead and say router delete.
04:43
Again, give the root name in here. Discussions destroy. Passing through the discussion. And then again, we don't necessarily need to worry about preserve scroll here,
04:57
because when we delete this over in here, we're going to be redirected back to the forum anyway. So let's actually skip that option entirely, because it's completely unnecessary. OK, so let's go ahead and try this out. Just bringing up my console just in case.
05:12
And let's hit delete here. Now, of course, that looks like it did absolutely nothing. So let's have a look here. I don't even think.
05:21
Did we hook this up to our button? So I put the if you probably notice this. So V on click. There we go.
05:29
OK, now we didn't add a wrapper around this to confirm. So let's do that really quickly. So if window confirm. Are you sure?
05:39
And if we are sure, then we go ahead and delete it. So let's try this out. OK, I'm going to cancel that off and hit OK. OK, so discussions destroy is not in the root list.
05:49
So obviously something's gone wrong there. Discussions and where are we? Discussions dot destroy. Great.
05:58
OK, so that should fix that up. Great. We're redirected back to the home page. And of course, you can see that discussion has now been deleted.

Overview
Ready to build a forum with Inertia and Laravel?
Why a forum? A forum touches a whole load of concepts that you'll use throughout your development career – particularly on the client-side, where we'll be doing most of the heavy lifting.
So, let's build a clean, modern forum with features like markdown support, code highlighting, advanced filtering, user mentions, full-text search, the ability to mark best answers, and more.
