AutoMigrate to add primary key is not working about gorm HOT 3 CLOSED

ID          uint32 `gorm:"primary_key;auto_increment;not null" json:"id"`

from gorm.

as far as I remember automigrate doesn't support altering columns. you need to drop the table and rebuild it, unless you're sure all your primaryID are unique you can set it manually in the database

I read some codes and realized that this behavior is expected.

as far as I remember automigrate doesn't support altering columns

that some changes like adding unique constraints, indexes etc worked made me feel like this behavior is a kind of bug.

I realized that if I want to AutoMigrate to add primary key, I have to change more codes than I expected (need additional methods for each drivers and so on). I have no idea if this worth commit so I close this issue for now.
