最佳答案
我刚刚把我的 python 从3.9.1升级到了3.9.4。当我试图运行服务器的时候。控制台对此给了我一个警告:
WARNINGS:
learning_logs.Entry: (models.W042) Auto-created primary key used when not defining a primary key type, by default 'django.db.models.AutoField'.
HINT: Configure the DEFAULT_AUTO_FIELD setting or the LearningLogsConfig.default_auto_field attribute to point to a subclass of AutoField, e.g. 'django.db.models.BigAutoField'.
learning_logs.Topic: (models.W042) Auto-created primary key used when not defining a primary key type, by default 'django.db.models.AutoField'.
HINT: Configure the DEFAULT_AUTO_FIELD setting or the LearningLogsConfig.default_auto_field attribute to point to a subclass of AutoField, e.g. 'django.db.models.BigAutoField'.
No changes detected in app 'learning_logs'
我能知道我该怎么补救吗。 我阅读了有关这方面的文档,但是我不明白这部分 这一页与这方面有什么关系。
Models.py
from django.db import models
from django.contrib.auth.models import User
# Create your models here.
class Topic(models.Model):
text = models.CharField(max_length = 200)

image = models.ImageField(upload_to = 'backgroud_images', null = True, blank = True)
owner = models.ForeignKey(User,on_delete = models.CASCADE)
def __str__(self):
return self.text
class Entry(models.Model):

class Meta:
