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

## 无效尝试

- **** — Increasing only DATA_UPLOAD_MAX_MEMORY_SIZE doesn't affect file upload limit. (60% 失败率)
- **** — Setting FILE_UPLOAD_MAX_MEMORY_SIZE=0 disables limit but can cause memory issues. (40% 失败率)
