Query lastest Relationship, When Account was Created - laravel

Question

I have two tables: Account and Transaction.
These tables relate to each other, by Account hasOne Transaction.
i want to show data in Transaction page, once Account was created.
My Account Model
public function transactions()
{
return $this->hasOne(\App\Transaction::class)->latest();
}
My Transaction Model
public function account()
{
return $this->belongsTo(\App\Account::class);
}
And my TransactionController
(I tried to implement code like below, but still no luck):
public function index()
{
$transactions = Transaction::with(['account' => function($query) {
$query->orderBy('id', 'desc')->first();
}]);
return response()->json(['transactions' => $transactions]);
}
Any Help? Thanks.....

Answer 1

QueryBuilder chains need either a get() or a first() or something of that nature at the end to execute the query, right now the variable you're passing to the view is the unexecuted query builder. Try this
$transactions = Transaction::with(['account' => function($query) {
$query->orderBy('id', 'desc')
}])->get();
Although, as TimLewis pointed out in the comments, if the relationship between transactions and accounts is one to one then there's no need to do any ordering of the account so it can just be this
$transactions = Transaction::with('account')->get();

Oooopppp i found what i want....
In my AccountController
public function store(Request $request)
{
$validateData = $request->validate([
'name' => 'required',
'code' => 'required',
]);
$account = new Account();
$account->user_id = auth()->user()->id;
$account->code = $request->code;
$account->name = $request->name;
$account->description = $request->description;
$account->balance = $request->balance;
$account->save();
$transaction = new \App\Transaction();
$transaction->credit = $request->balance;
$account->transaction()->save($transaction);
return response()->json(['created' => true]);
}
i have to save Transaction Relationship with Account.
