如何将本地文件分配给Django中的FileField? [英] How to assign a local file to the FileField in Django?
问题描述
AttributeError:'str'对象没有属性'open'
我的python代码:
pdfImage = FileSaver()
pdfImage.myfile.save('new',open('mytest.pdf')。read())
和我的models.py
class FileSaver(models.Model):
myfile = models.FileField(upload_to =files /)
class Meta:
managed = False
提前感谢您的帮助
Django使用它自己的文件类型(具有视觉增强功能)。无论如何,Django的文件类型类似于装饰器,因此您可以将其围绕现有文件对象进行包装满足Django API的需要。
从django.core.files导入文件
local_file =打开('mytest.pdf')
djangofile = File(local_file)
pdfImage.myfile.save('new',djangofile)
local_file.close()
您当然可以通过编写以下内容(一行少一行)来装饰文件:
pdfImage.myfile.save('new',File(local_file))`。
I was trying to assign a file from my disk to the FileField, but I have this error:
AttributeError: 'str' object has no attribute 'open'
My python code:
pdfImage = FileSaver()
pdfImage.myfile.save('new', open('mytest.pdf').read())
and my models.py
class FileSaver(models.Model):
myfile = models.FileField(upload_to="files/")
class Meta:
managed=False
Thank you in advance for your help
Django uses it's own file type (with a sightly enhanced functionality). Anyway Django's file type works like a decorator, so you can simply wrap it around existing file objects to meet the needs of the Django API.
from django.core.files import File
local_file = open('mytest.pdf')
djangofile = File(local_file)
pdfImage.myfile.save('new', djangofile)
local_file.close()
You can of course decorate the file on the fly by writing the following (one line less):
pdfImage.myfile.save('new', File(local_file))`.
