Root Cause

Uploaded file exceeds the in-memory upload limit.

generic

中文

上传文件超过内存中的上传限制。

Workarounds

  1. 90% success 
    Set FILE_UPLOAD_MAX_MEMORY_SIZE = 10485760 (10MB) in settings.py.
  2. 85% success 
    Use FILE_UPLOAD_HANDLERS to stream large files to disk: ['django.core.files.uploadhandler.TemporaryFileUploadHandler']

Dead Ends

Common approaches that don't work:

  1. 60% fail

    Increasing only DATA_UPLOAD_MAX_MEMORY_SIZE doesn't affect file upload limit.

  2. 40% fail

    Setting FILE_UPLOAD_MAX_MEMORY_SIZE=0 disables limit but can cause memory issues.
