Single email validation in Laravel Livewire

  • 772

I need to delve into the validation of a single field in Laravel , in my case with email .

I know the following functionality should work in Laravel

'email' => 'unique:App\User,email',

But this functionality in the Livewire form does not work in real time. When I get to submit, if the email is repeated, it gives me the following error:

laravel Integrity constraint violation: 1062 Duplicate entry email unique

I do not know the functionality of it, I assumed that this avoided the error and validated that the mail is unique in the form. This is not the case, would I be missing something?

Or should I do the rule manually?

$usuario = User::where('email', $email);

I really appreciate your time spent on my consultation.

    Analyzing the Livewire validation I found a cool method in real time.

    https://laravel-livewire.com/docs/input-validation

    public function updated($field)
{
    $this->validateOnly($field, [
        'email' => 'unique:App\User,email'
    ]);
}

  2. Well not if it's a little late but hopefully it will help someone.

    For when a record is created and you want it to be unique I do it like this

    protected $rules = [
    'email' => 'required|min:3|email|unique:App\Models\User,email',
];

    and use this for realtime validation

    public function updated($propertyName)
{
    $this->validateOnly($propertyName);
}

    to do the validation when updating a single record you can do it in the following way depending on how you have in the $rules

    In my case I do it like this since I handle different controllers both to create and to update

    function rules() {
    return [
        'user.email' => 'required|min:3|email|email|unique:App\Models\User,email,'. optional($this->user)->id,
    ];
}

    And to activate the validation in real time the following is added

    public function updated($propertyName)
{
    $this->validateOnly($propertyName);
}
