[FIXED] How to get the id of current saved model in Laravel

Issue

On the store() method of a model, I want to save two more models. I need the id of the current model that I am storing. How can I get that?

Controller

public function store(Request $request, Property $property)
{
    /*******************************************************
     * Validation sent data
     * Validate e forme ersali user
     *******************************************************/

    $data = $request->validate([
        'type' => 'required',
        'title' => 'required',
        'description' => 'required',
        'base_capacity' => 'required',
        'max_occupancy' => 'required',
    ]);

    Property::create($data);

    PropertyDetail::create([
        'property_id' => 1,
        'state' => $request->state,
        'city' => $request->city,
        'address' => $request->address,
        'post_code' => $request->post_code,
        'placearea' => $request->place_area,
        'telephone' => $request->telephone,
    ]);
}

Here I hard-coded the property id in the property detail. However, I want to get the id of the current property I just created above that.

Solution

Ok-ish approach

1. Create an instance of Property

$property = Property::create($data);

2. Reference it

PropertyDetail::create([
        'property_id' => $property->id, // here it is
        'state' =>$request->state,
        'city' =>$request->city,
        'address' =>$request->address,
        'post_code' =>$request->post_code,
        'placearea' =>$request->place_area,
        'telephone' =>$request->telephone,
    ]);

Safer approach

Safer approach is nearly identical, except you're using two queries and queries can fail. You want to make sure that either both succeed or none succeeds. For that, we use transactions.

What we're making safe about is ensuring data got to the database.

public function store(Request $request,Property $property)
{
    /*******************************************************
     * Validation sent data
     * Validate e forme ersali user
     *******************************************************/

    $data = $request->validate([
        'type' => 'required',
        'title' => 'required',
        'description' => 'required',
        'base_capacity' => 'required',
        'max_occupancy' => 'required',
    ]);

    \DB::transaction(function() use ($data, $request) {
        $property = Property::create($data);

        PropertyDetail::create([
            'property_id' => $property->id,
            'state' =>$request->state,
            'city' =>$request->city,
            'address' =>$request->address,
            'post_code' =>$request->post_code,
            'placearea' =>$request->place_area,
            'telephone' =>$request->telephone,
        ]);
    });
}
