Question

我对我的模型进行了一些修改，添加了一些图像字段并安装了Pillow，删除了一些模型或模型字段。

由于Site还没有投入生产，我只是删除了数据库并重新创建它，然后同步它。然后我收到了这个错误。

我无法弄清楚这突如其来的错误可能是什么原因。在settings.py中，我添加了一个media_root但没有别的。

Exception Type: TypeError at /
Exception Value: 'list' does not support the buffer interface

好吧，我的错。错误实际上非常明确。

与TEMPLATE_DIRS不同，MEDIA_ROOT不应该是列表。

Django Debug toolbar will return an error every time you mess up with variables types in
the "settings.py" file.

如果有人犯了类似的错误，我会在这里离开Q＆amp; A.
