1.Django修改表名

# 在Model中
class Meta:
db_table = "new_tablename" # 更改表名

2.Django增加表內容

1.直接在models.py中增加

class User(models.Model):
username=models.CharField(max_length=50)
password=models.CharField(max_length=50)
zhname = models.CharField(max_length=50)

我增加了zhname = models.CharField(max_length=50)
再依次執行

1.python manage.py makemigrations
2.python manage.py migrate

執行第一句時報錯

You are trying to add a non-nullable field 'name' to contact without a default; we can't do that (the database needs something to populate existing rows).
Please select a fix:
1) Provide a one-off default now (will be set on all existing rows with a null value for this column)
2) Quit, and let me add a default in models.py
Select an option:

解決方法：給zhname 給初值’abc’

zhname = models.CharField(max_length=50,default='abc')

然後依次執行

python manage.py makemigrations
python manage.py migrate

刪除default默認初始值default=‘abc’
再執行

python manage.py makemigrations
python manage.py migrate
