So back over to the forum index, we're going to add a bit of text down here, which is going to be the preview of the first post, just so we can get a little bit more context about what this discussion is as we're browsing the list.

00:12

So to start with, we're going to head over to our discussion resource and we're going to add a body preview to this. So let's do this just here, body preview. And for this, it's just going to be the body.

00:26

So the plain text body, no mark down here at all. But we're going to use Laravel string helper. Let's just pull this in. Here under illuminate support, and it's going to limit this string,

00:39

so we can just limit this by any amount, it doesn't really matter for now. What we're going to do with this, we just make that an integer, is use Tailwind's line clamp so it doesn't interfere with the size of what we're doing inside of the component.

00:54

We'll see that in a second. OK, so we've got our body preview. Let's go over to our discussion component and let's add this in. So let's see where we are.

01:04

This is the discussion title. Down here will be the body preview. So discussion body preview. And let's head over.

01:16

And yeah, what we've actually done here is added this to the discussion resource, which, of course, is not right. What we want to do is add this to the post resource itself because this is where we actually have the body.

01:27

So you probably spotted that. But let's go and just switch that over. Now, if we look at our discussion resource, we don't actually have the first post in here, but we do have the relationship

01:39

set up for this. Remember, we have this post relationship down here, which is the first post. So with this, what we can do is add in another relationship to this post, post resource and when loaded post.

01:56

So let's just check over on our forum index controller that we've loaded this. We haven't. So let's go ahead and load in the first post and we should be good. We should now be able to via the discussion and the first post access the body preview, which will now be post body preview.

02:14

And yeah, it doesn't work. So let's have a look. And yeah, it doesn't look like it is in there. So let's have a look here.

02:21

Discussion resource post when loaded post. And let's go ahead and dump this out and just see what we've got. So discussion and we will just get rid of this for now. And let's have a look in there.

02:37

So we've got the post in there and we should have the body preview. Now, for this one, we don't. That is the problem, because for the second discussion, we don't have any posts. Now, I'm not sure there's too much point

02:52

in protecting this because we should always have posts in there. But let's just create out a post for this other discussion just to make this work. So here is a post. We'll have that for my user and the discussion here will be this one.

03:12

The parent ID won't exist because that's the first post and let's switch up the created and updated update. If you ever find yourself not having posts within the discussion, you can just come in here and add some if

03:24

statements to make this work, so let's bring back the body preview. And now that should work for both of these. And we now have a preview of each of these in here, which is great. To finish up, let's just style this up.

03:34

So it looks a little bit better. So we're going to go ahead and mute the text on here because it's not hugely important, set the text to small, set a margin on the top. And we'll look at the line clamp in just a second.

03:46

So there we go. I think that looks OK. Now, what I'm going to do is just add a little bit more data to this. So let's just copy and paste this a few times just to fill this up, because, of course, a post body, at least the first one, could have quite a lot of data.

04:02

You can see this wraps down a couple of lines. Now we have over in our post resource the string limit on this body preview. So it's never going to go above 200 characters. However, that doesn't mean that we're

04:15

going to keep consistency on the long line. Different letters have different widths, so on. So what we can actually do within Tailwind is we can set a line clamp. So line clamp one will basically just keep this to a single line,

04:28

but have an ellipsis at the end with a cut off content. And of course, you can bump this up as well if you want to, to two lines. It really is up to you. But the fact we can do this within CSS,

04:40

not have any kind of complex logic to handle this in the back end makes a lot of sense. So there we go. We have a really nice cut off first line with a little bit of context about each of these discussions.

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.
