我在我的模型中添加了一个unicode () 方法,但是在交互中显示所有对象时它不起作用。
import datetime
from django.db import models
from django.utils import timezone
class Poll(models.Model):
question = models.CharField(max_length=200)
pub_date = models.DateTimeField('date published')
def _unicode_(self):
return self.question
def was_published_recently(self):
return self.pub_date >= timezone.now() - datetime.timedelta(days=1)
class Choice(models.Model):
poll = models.ForeignKey(Poll)
choice = models.CharField(max_length=200)
votes = models.IntegerField()
def _unicode_(self):
return self.choice
# Create your models here.
(InteractiveConsole
>>> from polls.models import Poll, Choice
>>> Poll.objects.all()
[<Poll: Poll object>]
