Root Cause

A datetime field with timezone-aware requirement receives a naive datetime (no timezone info).

generic

中文

带有时区感知要求的日期时间字段接收到没有时区信息的朴素日期时间。

Workarounds

  1. 95% success 
    Use timezone-aware datetime: datetime.now(timezone.utc)
  2. 85% success 
    Allow naive datetime by removing tz constraint from Field

Dead Ends

Common approaches that don't work:

  1. 90% fail

    utcnow returns naive datetime, not timezone-aware.

  2. 80% fail

    This makes it naive, still fails.
