Importing CTFd-exported ZIP gives DateTime error

See original GitHub issue


  • CTFd Version/Commit: master
  • Operating System: Debian Testing
  • Web Browser and Version: N/A

What happened? In trying to import a ZIP file that was previously exported with CTFd, an error is thrown stating “SQLite DateTime type only accepts Python”

What did you expect to happen? I expected the data to import successfully

CTFd exports should be able to go between databases. They should be viewed as a single portable file that can go between CTFd instances.

I think there’s enough here to warrant some kind of fix so I’ll try to reproduce and come up with some general solution.

In that case I would probably see if you can modify the date format, or downgrade to 1.0.2, import, and then upgrade CTFd to master and run migrations.
