Create a document using python-docx and send as attachment through django

I have created a document using docx and tried to send as an email attachment without saving the document on the server. Below is my code:

Document = document()
paragraph = document.add_paragraph("Test Content")
f = BytesIO()
document.save(f)
file_list = []
file_list.append(["Test.docx",f, "application/vnd.openxmlformats-officedocument.wordprocessingml.document"]
email = EmailMessage(subject = 'Test', body = 'Hi', to = ['[e-mail]'], attachments = file_list)
email.send()

I am getting the following error:

TypeError: expected bytes-like object, not BytesIO

on the line email.send()

I tried converting BytesIO to StringIO as mentioned here

f = f.read()
f = StringIO(f.decode('UTF-8'))

and then I get the error:

TypeError: expected bytes-like object, not StringIO

I looked at the solution from this, but didn't understand how the document is sent as an attachment.

Any help or pointers is appreciated.

Thanks!

I'm not familiar with the library BUT:

BytesIO is basically a buffer of bytes in memory, somewhere your library wants bytes, not the buffer itself, hence the:

TypeError: expected bytes-like object, not BytesIO

In the file_list you're doing this:

file_list.append([filename, f, mime_type])

where f is the BytesIO. What you need is the value contained in it:

file_list.append([filename, f.getvalue(), mime_type])

you can see the documentation for that method here: docs.python.org/3/library/io.html#...

BTW you should probably tag this post as #help because... you're asking for help :D
