Django ContentFile() unexpected empty line (django.core.files.base)

Question

I have a problem with the ContentFile function of django.core.files.base

I wrote a function that allows me to save text into an .md file

def save(title,content)
    filename = f"entries/{title}.md"
    if default_storage.exists(filename):
        default_storage.delete(filename)
    default_storage.save(filename, ContentFile(content))

I am using a simple textarea in a form that submits the content to the route that will save it.
The problem is that after saving every new line is duplicated:

Hello
World

Becomes

Hello

World

And this happens all the time. If you have 2 empty lines you end up having 4 of them...

Am I doing something wrong?

Answer 1

I solved it by changing the last line of the save_entry function to

default_storage.save(filename, ContentFile(content.encode('ascii')))
