我一直在尝试运行这段代码,但它会抛出缩进错误。无论我尝试什么,结果都是一样的。
如果我删除
def __str__(self):
和其余代码前面的缩进,它就能正常工作,但输出时,它显示的不是问题,而是 'Question object'。def __str__(self):
^
IndentationError: unexpected indent
以下是代码:
from __future__ import unicode_literals
from django.db import models
from django.utils.encoding import python_2_unicode_compatible
from django.utils import timezone
class Question(models.Model):
question_text = models.CharField(max_length=200)
pub_date = models.DateTimeField('date published')
def __str__(self):
return self.question_text
def was_published_recently(self):
return self.pub_date >= timezone.now() - datetime.timedelta(days=1)
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
