Laravel 8: Call to undefined method Illuminate\Database\Eloquent\Relations\HasMany::sync()

We Are Going To Discuss About Laravel 8: Call to undefined method IlluminateDatabaseEloquentRelationsHasMany::sync(). So lets Start this PHP Article.

    public perform motion pictures()
    {
        return $this->belongsToMany(Movie::class);
    }

Movie.php:

public perform actors()
    {
        return $this->belongsToMany(Actor::class);
    }

in many-to-many relationship we should use belongsToMany()

As it’s a many-to-many relationship in each capabilities you want to use belongsToMany, so it is best to use:

Actor.php:

public perform motion pictures() {
    return $this->belongsToMany(Movie::class);
}

Instead of:

public perform motion pictures() {
    return $this->hasMany(Movie::class);
}

Movie.php:

public perform actors() {
    return $this->belongsToMany(Actor::class);
}

Instead of:

public perform actors() {
    return $this->hasMany(Actor::class);
}

sync() works solely for a lot of to many relationships.
