In Laravel, you can display related tables by using Eloquent relationships in your models. Here's a step-by-step guide to displaying related tables:

  1. Define the relationships in your models: Define the relationship in the primary model by using the hasOne, hasMany, belongsTo, belongsToMany methods. Define the inverse relationship in the related model by using the belongsTo, hasOne, hasMany, belongsToMany methods.
  2. Use eager loading to load related models: Use the with method in your query to load the related models along with the primary model. Eager loading helps reduce the number of queries executed when retrieving related models.
  3. Display the related data in your views: Access the related models as properties of the primary model in your views. Use blade templating to display the related data in your HTML.


Example code:

  1. Define the relationships in your models:
 1
 2
 3
 4
 5
 6
 7
 8
 9
10
11

// User Model
class User extends Model
{
    public function posts()
    {
        return $this->hasMany(Post::class);
    }
}

// Post Model
class Post extends Model
{
    public function user()
    {
        return $this->belongsTo(User::class);
    }
}


  1. Use eager loading to load related models:
1
2
3
4
5
// Controller
$users = User::with('posts')->get();

return view('users.index', compact('users'));


  1. Display the related data in your views:
1
2
3
4
5
6
7

<!-- users.index.blade.php -->
@foreach($users as $user)
    <h2>{{ $user->name }}</h2>
    <ul>
        @foreach($user->posts as $post)
            <li>{{ $post->title }}</li>
        @endforeach
    </ul>
@endforeach


This will display a list of users along with their related posts. Remember to replace the model and relationship names with your actual models and relationships in your application.
