postのvalidationを設定しよう

public function store(Request $request){
    	$this->validate($request, [
    		'login_id' => 'required|min:3',
    		'role' => 'required|min2',
    		'name' => 'required|min2',
    		'password' => 'required',
    		'mail' => 'required',
    		'test_mail' => 'required',
    		'updated_person' => 'required|min:3'
    	]);
    	$article = new Article();
    	$article->login_id = $request->login_id;
    	$article->role = $request->role;
    	$article->name = $request->name;
    	$article->password = $request->password;
    	$article->mail = $request->mail;
    	$article->test_mail = $request->test_mail;
    	$article->updated_person = $request->updated_person;
    	$article->save();
    	return redirect('/');
    }

password,　メールアドレスのバリデーションがよくわらんね。
