我正在django应用程序内部的app_name文件夹的根目录中运行脚本;就像在app_name> app_name中一样。
在脚本顶部,我有这个:
import os
import sys
os.environ.setdefault('DJANGO_SETTINGS_MODULE','versal.settings')
import django
django.setup()
我正在尝试处理完整性错误-我的子弹必须是唯一的,所以当一个不是唯一的时,我想通过在子弹上添加'1'来处理完整性错误。
try:
podcast_instance.slug = slugify(parsed_podcast.title)
podcast_instance.save()
podcast_saves += 1
except IntegrityError:
podcast_instance.slug = slugify(parsed_podcast.title + '1')
podcast_instance.save()
podcast_saves += 1
运行此代码时,我得到了:
Traceback (most recent call last):
File "podcasts.py", line 166, in <module>
podcasty()
File "podcasts.py", line 159, in podcasty
submit(podcast_objects,podcast_rss)
File "podcasts.py", line 73, in submit
except IntegrityError as e:
NameError: name 'IntegrityError' is not defined
答案 0 :(得分:4)
您需要先导入它,然后再使用它。
from django.db import IntegrityError
