Laravel: Validation unique on update

Just a side note, most answers to this question talk about email_address while in Laravel's inbuilt auth system, the email field name is just email. Here is an example how you can validate a unique field, i.e. an email on the update:In a Form Request, you do like this:public function rules()
{
  return [
      'email' => 'required|email|unique:users,email,'.$this->user->id,
  ];
}Or if you are validating your data in a controller directly:public function update(Request $request, User $user){ $request->validate([   'email' => 'required|email|unique:users,email,'.$user->id, ]);}Update: If you are updating the signed in user and aren't injecting the User model into your route, you may encounter undefined property when accessing id on $this->user. In that case, use:public function rules()  {   return [     'email' => 'required|email|unique:users,email,'.$this->user()->id,   ];  }A more elegant way since Laravel 5.7 is:public function rules(){  return [    'email' => ['required', 'email', \Illuminate\Validation\Rule::unique('users')->ignore($this->user()->id)]  ];}
