如何创建该文件并将其保存到 Django model？

Question

I want to create a file and save it to Django model within a view without creating any temporary files or anything like that. I plan to write a.txt file that contains information and I want to save the.txt file in the Django model.

Does anyone know how to do this?

Thank you

Yes – ContentFile .

Assuming a model

class Blah(models.Model):
    file = models.FileField(...)

you can use

from django.core.files.base import ContentFile

def view(request):
    content = b"Bla bla bla."
    file = ContentFile(content, name="my_file.txt")
    Blah.objects.create(file=file)

to create a model with something assigned to its file field without having had a file on disk.
