admin.py

class FooAdmin(admin.ModelAdmin):
    list_display = ('bar', 'is_new_bar') # is_new_bar is shown as True/False text, I want this as bool icon of django.

Answer 1

You can add method to your modeladmin that will return property value and set that it will return boolean:

class FooAdmin(admin.ModelAdmin):
     list_display = ('bar', 'get_is_new_bar') 

     def get_is_new_bar(self, obj):
        return obj.is_new_bar
     get_is_new_bar.boolean = True

Answer 2

Try this property use.

def is_new_bar(self):
    return bar == 'NEW'
is_new_bar.boolean = True
is_new_bar = property(is_new_bar)
