Root Cause

Attempting to access a session key that does not exist.

generic

中文

尝试访问不存在的会话键。

Workarounds

  1. 95% success Use .get() method 
    user_id = request.session.get('user_id')
  2. 90% success Check key existence 
    if 'user_id' in request.session: ...

Dead Ends

Common approaches that don't work:

  1. Using request.session['user_id'] without checking 90% fail

    Raises KeyError if missing.

  2. Assuming session always has the key 80% fail

    Session may be empty or expired.
