Question

我想在“模型”的模型名称中添加ImageField， 但是管理面板失败。我是初学者...我的失败是我知道的非常基本的例外，但我无法解决。

我该怎么办？（对不起，我英语不好，我是高中生）

型号代码

from django.db import models

# Create your models here.

#create a model and some models
class posting (models.Model):
    title=models.CharField(max_length=120,verbose_name='Başlık')
    content=models.TextField(verbose_name="İçerik")
    publishing_date=models.DateTimeField(verbose_name="Yayınlanma tarihi")
    photo=models.ImageField()

    #herposta title ına göre indexliyor

    def __str__(self):
        return self.title

异常说明：

很可能，您仍然需要创建数据库迁移manage.py makemigrations，然后运行它manage.py migrate。
