We have a lot of such fields in our database and never seen such an error. What I can think that may happen is that some row already assigned the id of 0, and changing the column type or adding a id column (which probably overrides the automatic one django generates for each model), and now it can convert the column.
Try to make a data migrations which adds +1 to all rows ids or reinserting that specific row (hopefully it won't be too hard), and see if it resolves your issue hope it helps On Thursday, January 5, 2023 at 12:09:35 PM UTC+2 prashan...@gmail.com wrote: > I'm using MySQL database in django when I am creating > > Id=models.AutoField(primary_key=True) > > It's showing below error. > -- You received this message because you are subscribed to the Google Groups "Django users" group.
