这是我的模板代码 bookSave.html

我可以保存所有内容，但是我需要保存文件路径并在本地保存文件。我阅读了他们的文档，但帮不上我的忙。请帮我解决这个问题

Answer 1

模型中的文件字段，除其他字段外，应如下所示：

class AddBook(models.Model):
    # file will be uploaded to MEDIA_ROOT/uploads
    file = models.FileField(upload_to='uploads/')
    # or...
    # file will be saved to MEDIA_ROOT/uploads/2015/01/30
    file = models.FileField(upload_to='uploads/%Y/%m/%d/')

在设置文件中，您需要将 MEDIA_ROOT 定义为您希望Django存储上载文件的目录的完整路径。（为了提高性能，这些文件未存储在数据库中。）将MEDIA_URL定义为该目录的基本公共URL。确保该目录可由Web服务器的用户帐户写入。

在settings.py中，您应该设置例如：

MEDIA_ROOT = '/home/foo/bar/yourproject/assets'

您可能还想研究和设置Django中的静态文件存储（“ static”文件夹除外）。

https://docs.djangoproject.com/en/2.0/howto/static-files/#configuring-static-files

在Django中，您可以使用File Object获取任何文件，例如：

from django.core.files import File

# Open an existing file using Python's built-in open()
f = open('/path/to/mybookfile.pdf')
myfile = File(f)

如何使用Django 2

View.py
