Description
As the title says, sometimes db_index=True doesn't apply
When performing makemigration, changes in db_index were checked, and when the contents were migrated, the contents were not applied to mysql.
Can you tell me what could be the reason for this and how to fix it?

Note:
See TracTickets
for help on using tickets.
MySQL doesn't support database indexes of various columns. I don't think you've explained the issue in enough detail to confirm a bug in Django. If you're having trouble understanding how Django works, see TicketClosingReasons/UseSupportChannels for ways to get help.
