How to display a boolean property in the django admin

Question

As we all know, displaying a method return value as boolean in the Django admin is easily done by setting the boolean attribute:

class MyMo         


        

Answer 1

Waiting for better solutions to come up, I've solved it in the following way:

class MyModel(models.Model):
    def _is_something(self):
        if self.something == 'something':
            return True
        return False
    _is_something.boolean = True
    is_something = property(_is_something)

I'll then reference the _is_something method in the ModelAdmin subclass:

class MyModelAdmin(admin.ModelAdmin):
    list_display = ['_is_something']

And the is_something property otherwise:

if my_model_instance.is_something:
    print("I'm something")
