Question

当我尝试在我的django项目中导入我的机场文件时，我得到以下内容：

INFO Downloading: airports.dat
Traceback (most recent call last):
  File "manage.py", line 10, in <module>
    execute_from_command_line(sys.argv)
  File "/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/django/core/management/__init__.py", line 350, in execute_from_command_line
    utility.execute()

    with open(self.download(), 'rt') as f:
  File "/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/airports/management/commands/airports.py", line 64, in download
    response.raise_for_status()

    raise HTTPError(http_error_msg, response=self)
requests.exceptions.HTTPError: 400 Client Error: Bad Request for url: https://raw.githubusercontent.com/jpatokal/openflights/master/data/airports.dat

为什么会这样？非常感谢

此修复程序是旁路：

使用浏览器将文件下载为airports.dat
修改django-Airports的源代码以防止下载，改为使用本地文件（原始来源被注释掉）：

    def handle(self, *args, **options):
        self.options = options

        if self.options['flush'] is True:
            self.flush_airports()
        else:
            columns = self.default_format.split(',')
            columns = dict(list(zip(columns, itertools.count())))

            with open("/home/<download_dir>/airports.dat", 'rt') as f:
            # with open(self.download(), 'rt') as f:
                self.stdout.flush()

最后，第158行的代码中存在一个小错误，在命令完成之前还需要修复（cities__in而不是city__in）：

            try:
                c = qs.filter(cities__in=City.objects.filter(
                    location__distance_lte=(point, D(km=25))))[0]  # second attempt
            except KeyError:
                c = None  # shit happens

请注意，处理需要一段时间，但最后，我确实得到了我所追求的机场名单。
