更新csv-fi有困难

Question

我试图用一个描述列更新CSV文件。我试图通过添加description = models.CharField(max_length=200, default='SOME STRING')向模型添加更新，如下所示：

wine = models.ForeignKey(Wine)
    pub_date = models.DateTimeField('date published')
    user_name = models.CharField(max_length=100)
    comment = models.CharField(max_length=200)
    rating = models.IntegerField(choices=RATING_CHOICES)
    description = models.CharField(max_length=200, default='SOME STRING')

为此更改运行“迁移”时，出现以下错误：

c:\Users\Amira Joshi\Desktop\winerama>python manage.py makemigrations
Migrations for 'reviews':
  reviews\migrations\0002_review_description.py
    - Add field description to review

我该怎么解决？请帮帮我！你知道吗

Answer 1

这不是一个错误：

c:\Users\Amira Joshi\Desktop\winerama>python manage.py makemigrations 
Migrations for 'reviews':   reviews\migrations\0002_review_description.py
    - Add field description to review

django说迁移文件已经创建，现在您必须通过运行以下命令来应用迁移：

python manage.py migrate
