Formation a custom widget value to look like custom date

Question

I have a custom widget, and I want to format the value as Date.

The widget value from database(is a DateField) is the following format:

2018-04-10 and I want to be shown to user like this: Tue Apr 03 2018

I tried using a template filter:

{% if widget.value != None %} value="{{ widget.value|date:'M d, Y'}}"{% endif %}

but the field value gets empty.

Answer 1

When you pass date to the template, you do not need to convert it to any format

is the following format: 2018-04-10

Django date template filter takes an argument python datetime object and converts to the specified format (|date:'M d, Y')

I guess, widget.value contains string '2018-04-10', in this case, django date template filter will not work. You can write your own template filter to convert string to python datetime object and then apply date - (widget.value|own_filter|date:'M d, Y') or, the best solution, check the widget argument, it should be python datetime object.

P.S. You can little improve your code:

{% if widget.value %} value="{{ widget.value|date:'M d, Y'}}"{% endif %}
