<?php
#app/Models/Posts.php

namespace App\Models;

use Illuminate\Database\Eloquent\Factories\HasFactory;
use Illuminate\Database\Eloquent\Model;

class Posts extends Model
{
    use HasFactory;

    /**
    * Write code on Method
    *
    * @return response()
    */

    protected $fillable = [
        'title',
        'body'
    ];

    /**
    * Get the comments for the blog post.
    */
    public function comments()
    {
        return $this->hasMany(Comments::class);
    }

Using get method

You can filter models that do not have any related items.

@if($posts->has("comments")->get())
    {{-- Post has comments --}}
@else
    {{-- Post does not have comments --}}
@endif

Using count method

Model to you already have loaded the collection, and you can call the count() method of the collection.

@if($posts->comments->count())
    {{-- Post has comments --}}
@else
    {{-- Post does not have comments --}}
@endif

Using exists

If you want to check without loading the relation, then you can run a query on the relation.

@if($posts->comments()->exists())
    {{-- Post has comments --}}
@else
    {{-- Post does not have comments --}}
@endif

using relationLoaded

You want to check if the collection was eager loaded or not.

@if($posts->relationLoaded('comments'))
    {{-- Post has comments --}}
@else
    {{-- Post does not have comments --}}
@endif
