How to assign a local file to the FileField in Django?

Question

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

Answer 1

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))

If you don't want to open the file, you can also move the file to the media folder and directly set myfile.name with the relative path to MEDIA_ROOT :

import os os.rename('mytest.pdf', '/media/files/mytest.pdf') pdfImage = FileSaver() pdfImage.myfile.name = '/files/mytest.pdf' pdfImage.save()
