Es gibt ein paar Probleme mit dem Code:

• Einrückungen
• Benutzerklasse Import
• verwenden Blog statt blog.Blog

eine schnelle Lösung:

from django.db import models 
from django.utils import timezone 
from django.contrib.auth.models import User 


class Post(models.Model): 
    author = models.ForeignKey(User) 
    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 


class Comment(models.Model): 
    post = models.ForeignKey(Post, related_name='comments') 
    author = models.CharField(max_length=200) 
    text = models.TextField() 
    created_date = models.DateTimeField(default=timezone.now) 
    approved_comment = models.BooleanField(default=False) 

    def approve(self): 
     self.approved_comment = True 
     self.save()`enter code here` 

    def __str__(self): 
     return self.text
