#35047: Wrong sql query for migration --------------------------------------+---------------------------- Reporter: mgoldenbe | Owner: nobody Type: Bug | Status: new Component: Migrations | Version: 3.2 Severity: Normal | Keywords: sqlmigrate Triage Stage: Unreviewed | Has patch: 0 Needs documentation: 0 | Needs tests: 0 Patch needs improvement: 0 | Easy pickings: 0 UI/UX: 0 | --------------------------------------+---------------------------- I had the model:
```py class UserInfo(models.Model): user = models.ForeignKey(User, related_name='user_info', on_delete=CASCADE) picture = models.URLField(null = True, blank = True) paying = models.BooleanField(default = False) credits = models.DecimalField(max_digits=6, decimal_places=2) expiry = models.DateTimeField() usd_per_credit = models.FloatField(null = True, blank = True) content_count = models.IntegerField(default=0) suspended = models.BooleanField(default = False) suspended_request = models.TextField(null = True, blank = True) suspended_timestamp = models.DateTimeField(null = True, blank = True) def __str__(self): return str(self.user) ``` Then I changed the `usd_per_credit` field to be ``` usd_per_credit = models.FloatField(default = 0.00) ``` After running `makemigrations` and `migrate`, I ran `sqlmigrate` and got the following: ```sql BEGIN; -- -- Alter field usd_per_credit on userinfo -- ALTER TABLE "accounts_userinfo" ALTER COLUMN "usd_per_credit" SET DEFAULT 0.0; UPDATE "accounts_userinfo" SET "usd_per_credit" = 0.0 WHERE "usd_per_credit" IS NULL; ALTER TABLE "accounts_userinfo" ALTER COLUMN "usd_per_credit" SET NOT NULL; ALTER TABLE "accounts_userinfo" ALTER COLUMN "usd_per_credit" DROP DEFAULT; COMMIT; ``` The last line before COMMIT is wrong. It drops the default value which was correctly set. -- Ticket URL: <https://code.djangoproject.com/ticket/35047> Django <https://code.djangoproject.com/> The Web framework for perfectionists with deadlines. -- You received this message because you are subscribed to the Google Groups "Django updates" group.
