Tôi gặp sự cố khi truyền một hàm dưới dạng tham số cho một hàm khác. Đây là mã của tôi:
ga.py:
def display_pageviews(hostname):
pageviews_results = get_pageviews_query(service, hostname).execute()
if pageviews_results.get('rows', []):
pv = pageviews_results.get('rows')
return pv[0]
else:
return None
def get_pageviews_query(service, hostname):
return service.data().ga().get(
ids=VIEW_ID,
start_date='7daysAgo',
end_date='today',
metrics='ga:pageviews',
sort='-ga:pageviews',
filters='ga:hostname==%s' % hostname,)
models.py:
class Stats(models.Model):
user = models.OneToOneField('auth.User')
views = models.IntegerField()
visits = models.IntegerField()
unique_visits = models.IntegerField()
updatestats.py:
class Command(BaseCommand):
def handle(self, *args, **options):
users = User.objects.all()
try:
for user in users:
hostname = '%s.%s' % (user.username, settings.NETWORK_DOMAIN)
stats = Stats.objects.update_or_create(
user=user,
views=display_pageviews(hostname),
visits=display_visits(hostname),
unique_visits=display_unique_visits(hostname),)
except FieldError:
print ('There was a field error.')
Khi tôi chạy cái này: python manage.py updatestatsTôi gặp lỗi:
TypeError: đối số int () phải là một chuỗi, một đối tượng giống byte hoặc một số, không phải là 'danh sách'
Tôi không biết điều gì gây ra điều này. Tôi đã thử chuyển đổi nó thành một chuỗi, nhưng tôi gặp lỗi tương tự. Có ý kiến gì không?
Theo dõi đầy đủ:

Biên tập:
Được rồi, tôi hiểu vấn đề là gì. Tôi đã sử dụng shell để lấy kiểu đầu ra của hàm:
>>> type(display_pageviews('test.domain.com'))
<class 'list'>
Tôi đã thử với điều này nhưng nó vẫn được coi là một danh sách:
pv = pageviews_results.get('rows')[0]
return pv
