I have both ways in different apps.
To save to a file use like this
from xhtml2pdf.pisa import CreatePDF
...
# Type is _io.BufferedWriter.
with open(pdf_pn, 'wb') as f_out: # type: BinaryIO
created_ok = CreatePDF(html, dest=f_out)
To show the PDF on the browser use like this
from io import BytesIO
from xhtml2pdf.pisa import CreatePDF
def show_pdf():
...
response.headers['Content-Type'] = 'application/pdf'
# Type is _io.BytesIO
in_mem_stream = BytesIO() # type: BytesIO
CreatePDF(html, dest=in_mem_stream)
pdf = in_mem_stream.getvalue() # type: bytes
in_mem_stream.close()
return pdf
I generate the HTML in my controller using a template.
Like this
from string import Template
...
html_part2 += Template(template).safe_substitute(fields_dic)
html = html_part1 + html_part2 + html_part3 # type: str
...
