Display check mark and cross icons for property in Django admin console

Question

In the Django admin, if the field is a BooleanField or NullBooleanField, Django will display a nice "on" or "off" icon instead of True or False.

Now I don’t actually have a BooleanField in my model, I have a fior property that I would like to display icons, but when I try to do this, Django screams that 'SomeAdmin.list_filter[0]' refers to 'is_activated' which does not refer to a Field.

Is it possible to display these cute little icons for this field without hacking Django too much.

thanks

You do not want to use list_filter . The property you are looking for is list_display . The documentation provides an example of how you can create a column that behaves like a boolean on a display. In short, you are doing something like this:

• Create a method in the class:

   def is_activated(self) if self.bar == 'something': return True return False 

• add the attribute of the .boolean method directly below the is_activated method:

   is_activated.boolean = True 

• Add the method as a field to list_display :

  class MyAdmin (ModelAdmin): list_display = ['name', 'is_activated']

• You will notice that the column name is probably now “activated” or something like that. If you want the column heading to change, you use the short_description method short_description :

   is_activated.short_description = "Activated"
