Root Cause

Uploaded file size exceeds the limit defined in DATA_UPLOAD_MAX_MEMORY_SIZE.

generic

中文

上传文件大小超过 DATA_UPLOAD_MAX_MEMORY_SIZE 中定义的限制。

Workarounds

  1. 90% success 
    Increase DATA_UPLOAD_MAX_MEMORY_SIZE = 10485760 (10MB) in settings.py.
  2. 85% success 
    Use streaming uploads or chunked uploads to handle large files.

Dead Ends

Common approaches that don't work:

  1. 50% fail

    Setting DATA_UPLOAD_MAX_MEMORY_SIZE=0 disables the limit but can cause memory exhaustion.

  2. 70% fail

    Only increasing FILE_UPLOAD_MAX_MEMORY_SIZE doesn't affect request body limit.
