Angular in XPages: Formatting Domino Data Services Date values with app.filter

In this article I will show how we can use the core angular date filter capabilities to format Date format, Domino data into an Angular.js based application

Introduction

In previous articles I have shown how to create a simple Angular.js application using a notes Domino Data Services feed from a notes database. If we want to add “date” information then we need a way to nicely format it. Using the Angular.js documentation page as reference I will show you how we can do this with Domino data.

Adding dates to our view

When we add a date field to a Domino Data Services feed we get something which is to the human eye pretty “ugly”

And when we add lastModified into our template, it is well, less than appealing….

Adding a formatting function to the template

We can modify the template to use a formatting function by changing up the template slightly and then adding a formatting filter to the application.

In the app.js we add the following

personApp.filter("formatDate", function () {
    return function (x) {
        return new Date(x);
    };
});

And then we reformat the template as such:

    <tr ng-repeat="person in people"  on-last-repeat>
        <td>{{person.firstname}}</td>
        <td>{{person.lastname}}</td>
        <td class="zipCode">{{person.zip}}</td>
        <td class="user">{{person.username}}</td>
        <td class="user">{{person.lastModified | formatDate | date:"dd MMM yyyy" }}</td>
        <td><a class="btn btn-info" href="#/person/{{person['@unid']}}">Edit</a></td>
        <td><a class="btn btn-warning" href="#/person/{{person['@unid']}}/delete">Delete</a></td>
    </tr>

The critical part is {{person.lastModified | formatDate | date:”dd MMM yyyy” }}.

The documentation unfortunately is not clear on this and I found this Stackoverflow example which worked perfectly. http://stackoverflow.com/a/25856275/1171653

The resulting page now looks formatted and much easier to read

Conclusion

I spent which a lot of time failing to achieve this date formatting without doing it the angular way. One quick google (or three) and I had the answer. Do it the angular way and oo look that that nice and simple formatting.

  1. The date format that Domino outputs in the JSON is a standard JavaScript date representation that conforms to ISO 8601. Angular can automatically convert that for you: you don’t need to add the custom filter. Writing {{person.lastModified | date : ‘dd MM yyyy’}} should be sufficient to format it. I’m lazy, so the less typing the better😉

    • You know, what I was actually working on had a much more complex filter and i simplified it for the blog. That’s funny and also very obvious, thanks Mark.

      People should listen to you😉
