$posts = DB::table('posts')->orderBy('id', 'desc')->get() ;
#
Post::orderBy('id', 'desc')->get() ;

#save
$p = new Post($request->all());

Миграции

Нужны чтобы создать таблицы физически на компьютере.

# .env  надо настроить сначала
php artisan migrate

    public function up()
    {
        Schema::create('posts', function (Blueprint $table) {
            $table->increments('id');
            $table->string("title");
            $table->string("slug");
            $table->text("body")->nullable();
            $table->integer("category_id")->nullable();
            $table->timestamps();
        });
    }

Контроллер

#
return view("posts.create", array("entity"=> $post ) ) ;
#
return redirect()->route("post.index")
