    Set FILE_UPLOAD_MAX_MEMORY_SIZE = 10485760 (10MB) in settings.py.

    Use FILE_UPLOAD_HANDLERS to stream large files to disk: ['django.core.files.uploadhandler.TemporaryFileUploadHandler']

无效尝试

常见但无效的做法:

  1. 60% 失败

    Increasing only DATA_UPLOAD_MAX_MEMORY_SIZE doesn't affect file upload limit.

  2. 40% 失败

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