《phthon编程从入门到实践》第十八章，从django入手，learning_Log项目

import os,django
from learning_logs import models
os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'learning_logs.settings')
django.setup()
class Topic(models.Model):
    text=models.name = models.CharField(max_length=200)
    date_added=models.DateTimeField(auto_now_add=True)
    
    def __str__(self):
        return self.text
class Entry(models.Model):
    """Something specific learned about a topic."""
    topic = models.ForeignKey(Topic)
    text = models.TextField()
    date_added = models.DateTimeField(auto_now_add=True)
    
    class Meta:
        verbose_name_plural = 'entries'
 
    def __str__(self):
        """Return a string representation of the model."""
        return self.text[:50] + "..."

网上看到好多解决方法，我也按照网上的方法把models改了一下但是还是不行，ps：我用的是vscode编辑器

解决bug

你应该是多了一层 learning_logs

试试 from learning_logs.learning_logs import models

from . import models试试呢

将目录设置为根目录呢

在learning_log/URLs.py加上app_nanm='learning_log'
