How to create a new object with a FileField field, in which to insert a file already on the server?

Question

Django

I'm trying to write a file on the server to a database object. The fact is that if I specify it via with open, then a new file is created in the wrong directory, next to the existing one and random characters at the end. How to specify a file that exists on the server so that it is created in the folder you need, which is given by the function from upload_to?

with open(myfile_path), "rb") as file:
    Document.objects.create(file=File(file))
