Answer 1

CarController.php
public function crear(Request $request){
request()->validate([
'patente' => 'required',
'marca' => 'required',
'modelo' => 'required',
'color' => 'required',
'fecha_ingreso' => 'required',
'patente' => 'required',
'marca' => 'required',
'modelo' => 'required',
'color' => 'required',
'fecha_ingreso' => 'required'
]);
$car = Car::create([
patente => $request->patente,
marca => $request->marca,
modelo => $request->modelo,
color => $request->color,
fecha_ingreso => $request->fecha_ingreso
]);
return redirect()->back();
}
Your code looks fine, a bit verbose, so I cleaned it up a bit and added validation. The only other thing I can think to suggest is ensure your Car model has the fields added to the protected $fillable array.

Just Validate Your data before store it,
php artisan make:request ClearRequest
in App\Requests\ClearRequest,
class ClearRequest extends FormRequest
{
/**
* Determine if the user is authorized to make this request.
*
* #return bool
*/
public function authorize()
{
return true;
}
/**
* Get the validation rules that apply to the request.
*
* #return array
*/
public function rules()
{
return [
'patente'=>'required',
'marca'=>'required',
'modelo'=>'required',
'color'=>'required',
'fecha_ingreso'=>'required',
'patente'=>'required',
'marca'=>'required',
'modelo'=>'required',
'color'=>'required',
'fecha_ingreso'=>'required'
];
}
}
in your controller
use App\Http\Requests\ClearRequest;
in your clear method
public function crear(ClearRequest $request){
...
}
in your view file sth like this,
<form action="/clear" method="POST">
#csrf
patente<br>
<input type="text" name="patente">
<br>
marca<br>
<input type="text" name="marca">
<br>
modelo<br>
<input type="text" name="modelo">
<br>
fecha_ingreso<br>
<input type="text" name="fecha_ingreso">
<br>
patente<br>
<input type="text" name="patente">
<br>
modelo<br>
<input type="text" name="modelo">
<br>
color<br>
<input type="text" name="color">
<br>
fecha_ingreso<br>
<input type="text" name="fecha_ingreso">
<br>
<input type="submit" value="Submit">
</form>
if it is helpful yor you upvote me :)

Answer 3

You are trying to store a null value in a NOT NULL column. Make sure you are passing patente correctly in the request.
