权限被拒绝尝试在Ubuntu上保存python-docx文件

Question

我想将 python-docx 文档保存到Ubuntu上具有777特权的目录中，但出现此错误：[Errno 13] Permission denied: 'media/Rooming Grand Oasis Cancun 2018-11-01-2018-11-30.docx'。

这是 Django Rest Framework 视图的代码：

def get_hotel_document(self, request, start_date, end_date, confirmed, hotel, bookings):
    from django.core.files import File
    from django.urls import reverse
    from docx import Document
    from docx.shared import Inches, Pt

    document = Document()

    section = document.sections[-1]
    section.left_margin = Inches(0.5)
    section.right_margin = Inches(0.5)

    style = document.styles['Normal']
    font = style.font
    font.name ='Arial'
    font.size = Pt(10)

    ... more code ...

    file_name = "media/Rooming {} {}-{}.docx".format(hotel, start_date, end_date)
    document.save(file_name)

    return file_name

在这里您可以看到目录的权限：

调用document.save(file_name)时出错。
