How to delete a post with a many to many link?

Question

Laravel

Good afternoon.
There are three tables
users
posts
users_posts
The task is to delete the post and the user who created it, knowing only the post id.
I will be glad for any help.

Answer 1

Do you need to delete a post and a user, or a post and a link?
Deleting a post and a link

$post = Post::findOrFail($id);
$post->user()->sync([]);
$post->delete();

Removing everything

$post = Post::findOrFail($id);
$post->user()->delete();
$post->delete();

Customization via migrations

Schema::create('users_posts', function (Blueprint $table) {
    $table->increments('id');
    $table->integer('user_id')->unsigned()->index();
    $table->foreign('user_id')->references('id')->on('users')->onDelete('cascade');
    $table->integer('post_id')->unsigned()->index();
    $table->foreign('post_id')->references('id')->on('posts')->onDelete('cascade');
});
