エクスプレスバリデータを使用して問題が発生しています。具体的にはisDate関数です。私はexpressvalidator、ボディーセレクト、バリデーターモジュールなどを使用するための措置を講じています。すべてのルートはこの後になります.. 環境はNode + Expressです。TypeError:req.checkBody(...)。オプション(...)。isDateが関数ではありません。
問題が
"req.checkBody('date_of_birth', 'Invalid date').optional({ checkFalsy: true }).isDate();"
の使用状況にあると私は、次のエラーを取得しておきます。
TypeError: req.checkBody(...).optional(...).isDate is not a function

app.js私のコントローラのいずれかで
app.use(logger('dev'));
app.use(bodyParser.json());
app.use(bodyParser.urlencoded({
extended: false
}));
app.use(expressValidator()); // Add this after the bodyParser middlewares!
app.use(cookieParser());
app.use(express.static(path.join(__dirname, 'public')));
app.use('/', index);
app.use('/users', users);
app.use('/catalog', catalog); // Add catalog routes to middleware chain.
、私は彼がAuthorSchema int型私は、別に定義した日に、いくつかの検証を行うためにISDATE()メソッドを使用しています。今
var AuthorSchema = Schema( {
first_name: {type: String, required: true, max: 100},
family_name: {type: String, required: true, max: 100},
date_of_birth: {type: Date},
date_of_death: {type: Date},
});
私はコントローラで、このコード持ってPOSTリクエスト処理する:
authorController.jsを - ラインからライン41-48
// Handle Author create on POST
exports.author_create_post = function(req, res, next) {
console.log("DEBUG: starting in exports.author_create_post");
req.checkBody('first_name', 'First name must be specified.').notEmpty();
req.checkBody('family_name', 'Family name must be specified.').notEmpty();
req.checkBody('family_name', 'Family name must be alphanumeric text.').isAlpha();
req.checkBody('date_of_birth', 'Invalid date').optional({ checkFalsy: true }).isDate(); // Error is on this usage of isDate()
req.checkBody('date_of_death', 'Invalid date').optional({ checkFalsy: true }).isDate();
ありがとうございます。私は、代わりに瞬間のisValid()を使用すると思います。 var dateFormat = "DD/MM/YYYY"; moment(req.body.date_of_birth、dateFormat、true).isValid(); –
