Livewire Update Validation on Unique Field

Hello!

How do you ignore an id while validating a unique field in livewire? I'm trying to update a user.

Here's my livewire class:

public User $user;
public $name;
public $username;
public $email;

protected $rules = [
    'name' => 'required|string|max:255',
    'username' => 'required|min:6|max:255|alpha_dash|unique:users,username,' . $this->user->id,
    'email' => 'required|string|email|max:255|unique:users,email,' . $this->user->id
];

public function updateForm()
{
     $validatedData = $this->validate();

     $this->user->update($validatedData);

     session()->flash('message', 'User successfully updated.');
}

I'm getting a Constant expression contains invalid operations error if I'll include $this->user->id in protected $rules = [].

I solve it by creating a rules function.

protected function rules()
{
    return [
        'name' => 'required|string|max:255',
        'username' => 'required|min:6|max:255|alpha_dash|unique:users,username,' . $this->userID,
        'email' => 'required|string|email|max:255|unique:users,email,' . $this->userID
    ];
}

public function updateForm()
{
    $validatedData = $this->validate();

    $this->user->update($validatedData);

    session()->flash('message', 'User successfully updated.');
}

You could have used the protected function for dynamic rules

protected function rules()
{
		return [
						'name' => 'required|string|max:255',
    					'username' => 'required|min:6|max:255|alpha_dash|unique:users,username,' . $this->user->id,
    					'email' => 'required|string|email|max:255|unique:users,email,' . $this->user->id
					];
}

Livewire invokes this function to set rules dynamically this way. (More about that here: https://laravel-livewire.com/docs/2.x/input-validation#introduction)

For all of those searching on this trying to use the ignore() fluent structure in Livewire, make sure it's wrapped in a rules() function first - then:

 protected function rules(){
        return [
            'vendor.display_name'    => ['required',
                'min:3',
                Rule::unique('vendor')->ignore($this->vendor->id)],
            'vendor.company_name'    => 'nullable|min:3',
            'vendor.check_name' => 'nullable|min:3',
			...
