Message:

1. Table Users => id, first_name, ...


2. Table Tags => id, name


3. Pivot Table user_tags => id, user_id, tag_id, ...

I'm using this in User Model:

public function tags()

{

  return $this->belongsToMany('App\Tag', 'user_tag');

}

And this in TagsController:

$users = User::with(['tags'])->get();

What I need is to get only users that have tags with empty users tag

My Answer:
In Laravel Eloquent, you can define relationships between models using functions. Here is an example of how you can define a relationship between the Users table and another table:

php
// 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);
}
}


In this example, we have defined a one-to-many relationship between the User and Post models. The `posts()` function in the User model defines that a user can have many posts, while the `user()` function in the Post model defines that a post belongs to a user.

You can then use these relationships to retrieve related data like this:

php
$user = User::find(1);
$posts = $user->posts;


This will retrieve all the posts associated with the user with ID 1. Similarly, you can retrieve the user associated with a post like this:

php
$post = Post::find(1);
$user = $post->user;
