Hello all,
I am working through the Django tutorial. I've made it to "Fixing the bug"
within part 5, but am having issues. The tutorial shows the following lines:
def was_published_recently(self):
now = timezone.now()
return now - datetime.timedelta(days=1) <= self.pub_date <= now
to be placed in polls/models.py.
I have made these changes and re-run the test:
$ python manage.py test polls
Which throws:
Creating test database for alias 'default'...
SystemCheckError: System check identified some issues:
ERRORS:
<class 'polls.admin.QuestionAdmin'>: (admin.E108) The value of
'list_display[2]' refers to 'was_published_recently', which is not a
callable, an attribute of 'QuestionAdmin', or an attribute or method on
'polls.Question'.
System check identified 1 issue (0 silenced).
I have gone into admin.py, but have been unable to spot the error. My
admin.py looks like:
from django.contrib import admin
from .models import Question, Choice
class ChoiceInline(admin.TabularInline):
model = Choice
extra = 3
class QuestionAdmin(admin.ModelAdmin):
fieldsets = [
(None, {'fields': ['question_text']}),
('Date information', {'fields': ['pub_date'], 'classes':
['collapse']}),
]
inlines = [ChoiceInline]
class QuestionAdmin(admin.ModelAdmin):
list_display = ('question_text', 'pub_date', 'was_published_recently')
list_filter = ['pub_date']
search_fields = ['question_text']
admin.site.register(Question, QuestionAdmin)
admin.site.register(Choice)
Does anyone have any recommendations as to what my issue might be?
Thanks,
John
