Inserting with relationships in laravel

I am facing a problem in Laravel 5.3 that I looked the docs and also searched web but didn't find anything on it.

I am using Laravel Relationships to join two tables. Now I want the data to be inserted on both the tables at the same time after the user submits a form. The catch in this is the first table is the primary one say "users" and second one "xyz" belongsTo the first table. The table "xyz" contains "users_id" column that connects both the tables. And obviously "users_id" is the "id" column of "users" table.

Now the problem arriving is that I want to insert the data in "users" table (that is easily done) and "xyz" table at the same time. The

User::create()
function will create the user data easily and it is working also but for inserting the data in "xyz" table I will be needing the "user_id" column data and ID will not be generated until the user is created as ID column has Auto-Increment attribute activated.

Code:

$user = new User;
$inputArry = array('data1' => $request['field1'],
'data2' => $request['field2'],
'data3' => $request['field3'],
);
$user->create($inputArry);
$user->xyz()->create([
'user_id' => $user->id,
'name' => $request['name'],
'about' => $request['desc'],
'tag' => $request['tag'],
]);


Above is the code that I am using for this purpose but it is giving me a error.

Error:

QueryException in Connection.php line 761:
SQLSTATE[23000]: Integrity constraint violation: 1048 Column 'soft_id' cannot be null (SQL: insert into `xyz` (`user_id`, `name`, `about`, `tag`, `updated_at`, `created_at`) values (, John, I am John, dev, 2016-11-09 21:01:29, 2016-11-09 21:01:29))

Answer

One way of inserting related table is using relations as:

$user = User::create($user_inputs);

$xyz = $user->xyz()->create($xyz_inputs);

It will automatically fills the user_id in the xyz table.
