AngularJS Question

Error: [ngModel:datefmt] Expected `2015-05-29T19:06:16.693209Z` to be a date - Angular

I'm working on

angular
application with
Django
with
rest-framework
..

The app receives it's info with json from the server.. One of the keys is
created_time
... The value of this field is format according to
iso-8601
, for example
2015-05-29T19:06:16.693209Z
.

In the client I have a field:

<input type="time" ng-model="created_time">


But when the data is arriving I get this error:

Error: [ngModel:datefmt] Expected `2015-05-29T19:06:16.693209Z` to be a date http://errors.angularjs.org/1.3.13/ngModel/datefmt?p0=2015-05-29T19%3A06%3A16.693209Z

I already tried everything :( the format is exactly as the instructions in the docs of angular...

Answer

This must be happening with angular 1.3+. 1.3+ on wards ng-model for date/time input needs to be a valid date object, string representation of date is no longer allowed. You need to convert string to date object ($scope.created_time = new Date(dateString)) and bind it to the ng-model. If you follow the error link it has a clear description about the error and how to resolve it.

All date-related inputs like require the model to be a Date object. If the model is something else, this error will be thrown. Angular does not set validation errors on the in this case as those errors are shown to the user, but the erroneous state was caused by incorrect application logic and not by the user.
