I have a model of customer i am storeing two things there one is user activation token and the other is forgot password token i want it random so i used uuid but when ever i am running migrate this migration always happening by the way i am not facing any functional error everything working fine but i have a feeling it might give me a error

CodePudding user response：

Just replace the uuid4 function call with the callable (that is, without brackets) and Django will know that the uuid is meant to remain constant.

forget_password_token = models.CharField(max_length=200,default=str(uuid.uuid4))
