《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] + "..."
运行结果及报错内容

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
