Question

我对djanggo 1.7有问题，我使用python 2.7

这个代码在models.py

中

class Tag(models.Model):

    title           = models.CharField(max_length=50)
    description     = models.TextField()
    created_date    = models.DateTimeField(default = timezone.now)
    published_date  = models.DateTimeField(blank=True, null=True)

    def publish(self):
        self.published_date = timezone.now()
        self.save()

    def __str__(self):
        return self.title

class Post(models.Model):

    author          = models.ForeignKey('auth.User')
    category        = models.ForeignKey(Category)
    tag             = models.ForeignKey(Tag)
    title           = models.CharField(max_length=200)
    text            = models.TextField()
    created_date    = models.DateTimeField(default = timezone.now)
    published_date  = models.DateTimeField(blank=True, null=True)

    def publish(self):
        self.published_date = timezone.now()
        self.save()

    def __str__(self):
        return self.title

这是urls.py

from django.conf.urls import patterns, include, url
from . import views

urlpatterns = patterns('',
    url(r'^$', views.post_list),
    url(r'^post/(?P<pk>[0-9]+)/$', views.post_detail),
    url(r'^post/new/$', views.post_new, name='post_new'),
    url(r'^post/(?P<pk>[0-9]+)/edit/$', views.post_edit, name='post_edit'),
)

我成功完成了迁移，但是当我尝试/manage.py迁移时，我会收到这样的错误

TypeError: int() argument must be a string or a number, not 'datetime.date'

你可以帮我解决这个问题吗？

Answer 1

而不是models.DateTimeField(default = timezone.now)尝试models.DateTimeField(auto_now_add=True)

int（）参数必须是字符串或数字，而不是'datetime.date'
