这些是我的应用的型号,但上面的标题有错误。
from django.db import models
class Question(models.Model):
question_text = models.CharField(max_length=200)
pub_date = models.DateTimeField('date published')
def __str__(self):
return self.question_text
class Choice(models.Model):
question = models.ForeignKey('question', on_delete=models.CASCADE)
choice_text = models.CharField(max_length=200)
votes = models.IntegerField(default=0)
def __str__(self):
return self.choice_text
import datetime
from django.db import models
from django.utils import timezone
class Question(models.Model):
def was_published_recently(self):
return self.pub_date >= timezone.now() - datetime.timedelta(days=1)
有可能解决这个问题吗?
错误:votes.Choice.question:(fields.E300)字段定义关系 与模型'问题',未安装或抽象。
