Flask Pdfkit create pdf from template and save it

I use pdfkit to create an invoice pdf. At the moment I just want to save it. Later I will save the invoice filename in the DB and store in on AWS3.

But for now I get an IO Error when trying to save the file, probably because I request it the wrong way:

pdfkit.from_file(render_template('invoice_template.html', invoice_id=1, invioce_date_start=str(date.today()),
                                     invioce_date_end=str(date.today()), invioce_company_name=form.zahlung_firma.data, invioce_user_vorename=form.vorname.data,
                                     invioce_user_surname=form.nachname.data, invioce_user_email=current_user.email), str(current_user.id) + '-invoice.pdf')

The Error:

    Traceback (most recent call last):

    response = self.full_dispatch_request()

    raise IOError('No such file: %s' % self.source)
IOError: No such file: <!doctype html>

The template itself can be found here, I just edited the jinja variables:

pdfkit.from_file() expects a file object as its input, but render_template() returns a string. Try pdfkit.from_string() instead.
