python - Django 模型 FileField 大文件上传

问题描述

我需要在 Django 模型中使用 FileField 字段时上传大文件（大约 1GB）。这给出了错误 DATA_UPLOAD_MAX_MEMORY_SIZE。我想我需要在保存模型时使用分块上传。我怎样才能做到这一点？或者有没有其他解决方案？

我的模型：

class Software(AbstractBasicFTPSupportModel):
category = models.ForeignKey(
    to="SupportCategory", related_name="softwares", on_delete=models.CASCADE, verbose_name=_("category"),
)
related_products = models.ManyToManyField(
    "product.Product", blank=True, related_name="softwares", verbose_name=_("related products")
)
software_file = models.FileField(
    upload_to=save_support_file, verbose_name=_("software file"), null=True, blank=True, max_length=255,
)

解决方案

在 settings.py 中设置 FILE_UPLOAD_MAX_MEMORY_SIZE
