What is the best way to automatically add a date and timestamp to every new entry?

I am currently working on a project that utilizes AngularJS and Ionic frameworks. The main feature of the project will involve users inputting data to create a list, and allowing any user to comment on each item in the list.

One challenge I have encountered is how to include a timestamp for when a user adds an item to the list or comments on it.

After some research, I discovered that AngularJS has a built-in method called "[ ].created" which can be used for this purpose. However, when I attempted to implement it without using controllers, it did not work as expected. I then tried adding JavaScript code, but that also failed. Here is the code snippet:

I am unsure if this issue could be related to compatibility with Ionic. Any assistance would be greatly appreciated, especially if I can stick to using the AngularJS method. Thank you!

Refer to the AngularJS documentation for more information on dates


Below is the resultant code with added filter:

HTML section (including ng-controller="MainCtrl")

<div class="post row" ng-repeat="post in posts"></div>

<a href="{{ post.url }}">{{ post.title }}
     <span class="url">({{ post.url | hostnameFromUrl }})</span>
</a>

<br> {{ post.created | date }}  
<!-- This is the added AngularJS code -->

I'm not sure what your goal is with the use of the "$scope.post" variable.

If you create a static object like this: "$scope.post = {url: 'http://', title: ''};", it will return undefined because there is no "get()" function defined for it.

Instead, consider using the Angular $http component to retrieve data from the server. You can learn more about it <a href="https://docs.angularjs.org/api/ng/service/$http" rel="nofollow">here</a>.

Additionally, both "$scope.post[0]" and "post.getDate" will also result in undefined values.

To get the date, you should use: $scope.date = post.getDate($scope.post[0].created);
