was_published_recently() takes 1 positional argument but 2 were given

Using Django Getting Started

I am currently going through the Django Documentation building the Polls App. And part 7 where there is the documentation asbout the Admin dashboard.
I have problem with this line of code which gives me error.

class QuestionAdmin(admin.ModelAdmin):
    fieldsets = [
        ('Question', {'fields': ['question_text']}),
        ('Date information', {'fields': ['pub_date']}),
    ]
    inlines = [ChoiceInline]
    list_display = ('question_text', 'pub_date', 'was_published_recently')
    @admin.display(
        boolean=True,
        ordering='pub_date',
        description='Published recently?',

was_publish_recently is the problem here.
What could be the issue here.

here is the error code

# TypeError at /admin/poll/question/

was_published_recently() takes 1 positional argument but 2 were given

In the tutorial, the decorator and the was_published_recently function go in the model class, not the model admin class. See Writing your first Django app, part 7 | Django documentation | Django
