How to display post category in laravel?

Question

Laravel

Like on the main page, where pots are displayed, display the category of each post.
PostController code:

<?php

namespace App\Http\Controllers\Posts;

use Illuminate\Http\Request;
use App\Http\Controllers\Controller;
use App\Post;

class PostController extends Controller
{
    public function index()
    {
    	$posts = Post::orderBy('updated_at', 'desc')->where('status', 1)->get();
        $categories = \App\Category::categoryAll();
    	return view('posts.index', compact('posts', 'categories'));
    }

    public function view($id)
    {
    	$post = Post::where('status', 1)->find($id);
    	$data = [
    		'post' => $post,
    	];
    	return view('posts.view', $data);
    }
}

Post and Category model code:

<?php

namespace App;

use Illuminate\Database\Eloquent\Model;

class Category extends Model
{
    public function post()
    {
    	return $this->hasMany('App\Post', 'category_id');
    }

    public static function categoryAll()
    {
    	return Category::get();
    }
}

<?php

namespace App;

use Illuminate\Database\Eloquent\Model;

class Post extends Model
{
    public function category()
    {
    	return $this->hasOne('App\Category', 'id');
    }

    public static function latestPost()
    {
    	return Post::orderBy('updated_at', 'desc')->where('status', 1)->limit(5)->get();
    }
}

index.balde.php:

@extends('layouts.app')

@section('content')
<section class="posts">
        <div class="jumborton">
            <h1>Блог<span>.</span></h1>
        </div>
@if (count($posts) > 0)
@foreach ($posts as $post)
        <article class="post">
            <div class="post-img"><a href="#"><img src="{{ asset('assets/img/' . $post->img) }}"></a></div>
            <div class="post-text">
                <h2>{{ $post->title }}</h2>
                <p class="post-text-information"><span>Категория:</span> <a href="#">{{ $post->category->title }}</a>  <span>{{ $post->updated_at }}</span>   <a href="#">5 комментариев</a></p>
                <p class="post-text-article">{{ $post->description }}</p>
                <a class="btn" href="{{ url('post', ['id' => $post->id]) }}">Продолжить чтение</a>
            </div>
        </article>
@endforeach
@else
    <h1>Постов пока нет!</h1>
@endif
        <div class="pagination">
            <ul>
                <li><a href="#">1</a></li>
                <li><a href="#">2</a></li>
                <li><a href="#">></a></li>
            </ul>
        </div>
    </section>
@endsection

All this throws this error

Answer 1

Try:
yes

public function category()
{
    return $this->hasOne('App\Category', 'category_id');
}

or so

public function category()
{
    return $this->belongsTo('App\Category', 'category_id');
}

UPD: If the classes are in the same directory, you can write Category::class instead of 'App\Category'
