TypeError：int（）参数必须是字符串，类字节对象或数字，而不是datetime.datetime
好的..我删除了完整的数据库。 EVEN重启我的电脑。
Models.py
from django.db import models
from django.core.urlresolvers import reverse
class Register(models.Model):
first_name = models.CharField(max_length=50)
last_name = models.CharField(max_length=50)
username = models.CharField(max_length=50)
password = models.CharField(max_length=50)
confirm_password = models.CharField(max_length=50)
email = models.EmailField(max_length=100)
position = models.CharField(max_length=50)
def get_absolute_url(self):
return reverse('user:register', kwargs={'pk': self.pk})
class Login(models.Model):
username = models.CharField(max_length=50)
password = models.CharField(max_length=50)
def __str__(self):
login = {'username': self.username, 'password': self.password}
return login
我没有设置主键或外键，但它仍然困扰着我。 我搜索并尝试了其他选项，但仍然无法找出问题和解决方案。 makemigrations没有给出错误，但是migrate命令给出了。
完整筹码：
D:\Python Projects\Project_Management>python manage.py makemigrations user

我创建了全新的数据库.. 请帮忙.. 提前谢谢。
答案 0 :(得分：4)
您要将 this.stop();
///////////////////////////////////////////////////////////////////////////////////////////////////////
// gestion du temps
///////////////////////////////////////////////////////////////////////////////////////////////////////
this.leTimeOut = window.setTimeout(punir.bind(this), 31000);
this.lInterval = window.setInterval(afficherTemps.bind(this), 1000);
/////////////////////////
Cutted section
////////////////////////
console.info("!!! "+nbMatchs+" !!!");
this.txtItems.text = ""+(6-nbMatchs);
if(nbMatchs == 6){
window.clearTimeout(this.leTimeOut);
this.gotoAndStop("FinNiveau1");
}
return bonnePosition;
}
///////////////////////////////////////////////////////////////////////////////////////////////////////

this.txtTimer.text = "29";

clearTimeOut(this.leTimeOut);
evt.remove(); //retrait de l'écouteur (la méthode facile!)
this.parent.gotoAndStop("Intro");
}
的默认值定义为ForeignKey个对象。 datetime应该是ForeignKey，表示其他某个表的ID。
问题在于这段代码
Integer更具体地说，
migrations.AddField(
model_name='login',
name='user_id',
field=models.ForeignKey(default=datetime.datetime(2016, 9, 10, 18, 43, 28, 263522, tzinfo=utc), on_delete=django.db.models.deletion.CASCADE, primary_key=True, related_name='login_id', serialize=False, to='user.Register'),
preserve_default=False,
),
将field=models.ForeignKey(default=datetime.datetime(2016, 9, 10, 18, 43, 28, 263522, tzinfo=utc), on_delete=django.db.models.deletion.CASCADE, primary_key=True, related_name='login_id', serialize=False, to='user.Register')
参数更改为您引用的default所代表的行的ID的值。
