How to present flags in django admin list view ( flags which are active )

[maharshi-trendlyne]

I have a model with BitField like this:

class MyModel(models.Model):
        notifications = BitField(flags=('facebook', 'phone', 'gmail'))

Say facebook, gmail are active, then in list view(django-admin) want those flag label comma separated.

Way too late but perhaps useful for someone else.

You can define a method in your AdminModel to represent them as you want, and then list it in the list_display attr.
For instance, what I did is to list it in its own column named Features, and if the flag is ON show a ✅ , and if it's OFF a ❌

list_display = (
   "features_repr"
)
@admin.display(description="Features")
    def features_repr(self, obj):
        repr = ""
        check_mark = "✅"
        cross_mark = "❌"

        for feature_name, is_set in obj.features.iteritems():
            feature_name = obj.features.get_label(feature_name)
            status_mark = check_mark if is_set else cross_mark

            repr += f"<b>{feature_name}:</b> {status_mark}<br>"

        return format_html(repr)

I called my model field features but your's should be obj.notifications
