对DB columns nam使用reserve Python关键字的Django模型

Question

我正在开发一个Django restfulapi&我的DB coulmn名称（即lambda与保留的python关键字冲突），我需要在包含代码的model.py文件中使用它

CHOICES = (
    (1, 'Default'),
    (0, 'Not Default'),
    )

    profileid = models.AutoField(primary_key=True)
    alpha = models.FloatField()
    beta = models.FloatField()
    gamma = models.FloatField()
    lambda = models.FloatField() # <---------- How to use lambda for column name
    is_default = models.IntegerField(choices=CHOICES)

**我希望在不重命名DB列名的情况下执行此操作

有什么建议吗？在

您可以使用^{}来进行相同的操作。根据文件，它应该工作：

my_lambda = models.FloatField(db_column='lambda')

The name of the database column to use for this field. If this isn’t given, Django will use the field’s name.

If your database column name is an SQL reserved word, or contains characters that aren’t allowed in Python variable names – notably, the hyphen – that’s OK. Django quotes column and table names behind the scenes.
