LARAVEL Eloquent: link post to user then user to profile - php

Question

I am aiming on retrieving the user image (from profile table column 'profile_img') and display on each post's footer.
I can retrieve the name of the author using $post->author->name and the profile picture using $post->author->profile->profile_image but it only works when i have a single record (post). when there is more than one record i get an error Trying to get property 'profile' of non-object (View: xampp/........../home.blade.php)
Can somebody show me where do i go wrong??
Models:
User
public function post()
{
return $this->hasMany('App\Post');
}
public function profile()
{
return $this->hasOne('App\Profile');
}
Profile
public function user()
{
return $this->belongsTo('App\User');
}
Post
public function author()
{
return $this->belongsTo('App\User', 'id');
}
controller
<?php
namespace App\Http\Controllers;
use Illuminate\Http\Request;
use App\Post;
class MainController extends Controller
{
public function index() {
$posts = Post::paginate(9);
return view('pages.home')->with('posts', $posts);
}
home view
#if(count($posts) > 0)
#foreach($posts as$posts)
<div>
<div class="post-title"><h3>{{$post->title}}</h3></div>
<div class="post-description">
{!!mb_substr($post>body,10,rand(35,40)) !!} ....
</div>
<div class="featured-details">
<div class="p-clearfix">
<img class="authorimg"src="/storage/profile_images/{{ $post->author->profile->profile_image }}">
<div class="author-title lite">{{ $post->author->name }}</div>
<div class="lite thumbnail-date">{{ date('M j, Y', strtotime($post->created_at)) }}</div>
</div>
</div>
</div>
<hr>
#endforeach
#else
no post yet
#endif

Answer 1

There appears to be some issues in your home view. Try it again with this code and see.
Home View
#if(count($posts) > 0)
#foreach($posts as $post)
<div>
<div class="post-title"><h3>{{$post->title}}</h3></div>
<div class="post-description">
{!!mb_substr($post>body,10,rand(35,40)) !!} ....
</div>
<div class="featured-details">
<div class="p-clearfix">
<img class="authorimg"src="/storage/profile_images/{{ $post->author->profile->profile_image }}">
<div class="author-title lite">{{ $post->author->name }}</div>
<div class="lite thumbnail-date">{{ date('M j, Y', strtotime($post->created_at)) }}</div>
</div>
</div>
</div>
<hr>
#endforeach
#else
no post yet
#endif
You can even go further and avoid the n+1 problem for authors by running your eloquent model query like this om your controller
<?php
namespace App\Http\Controllers;
use Illuminate\Http\Request;
use App\Post;
class MainController extends Controller
{
public function index() {
$posts = Post::with("author")->paginate(9);
return view('pages.home')->with('posts', $posts);
}
I hope this helps.

Answer 2

In your controller index method try with :
public function index() {
$posts = Post::with("author.profile")->paginate(9);
return view('pages.home')->with('posts', $posts);
}
And update post model relationship:
public function author()
{
return $this->belongsTo('App\User', 'user_id'); // update to users table foreign key
}
