djangoの日付解析/タイプエラー

Question

があります！

私はこのバグを少しでも乗り越えようとしています。私はstackoverflowを検索しても非常に似た投稿を見つけましたが、示唆された解決策のどれも私のために働いていませんでした。

これは私がコンソールに取得エラーです：

TypeError: expected string or buffer 

これは私のmodel.pyです：私はそれがDateTimeField型とは何かを持って推測している同様の質問から

from __future__ import unicode_literals 
from django.db import models 
from django.core.urlresolvers import reverse 
#from django.utils import 


# Create your models here. 
class Post(models.Model): 
    title = models.CharField(max_length=120) 
    image = models.FileField(null=True, blank=True) 
    content = models.TextField() 
    timestamp = models.DateTimeField(auto_now = False, auto_now_add = True) 

    def __unicode__(self): 
     return self.title 

    def __str__(self): 
     return self.title 

    def get_absolute_url(self): 
     return reverse("posts:detail", kwargs = {"id": self.id}) 
     #return "/posts/%s/"(self.id) 

私がそれを与えた何らかの議論を解析する問題があります。

ご協力いただきありがとうございます！

Answer 1

私は実際に新しいものを作り、私の移行フォルダの名前を変更することになったし、次のコマンドを実行している：

python manage.py makemigrations posts 
python manage.py migrate posts 

おかげ@FeFiFoFu、あなたの先端を正しい道に私を導く
