Just looking at your test5
document is unused (why do you need this object)?
output is a StringIO but you never write anything in it.
You call both response.write(output.getvalue()) and return
output.getvalue(). I think you only want the latter.
I think this: "attachment; filename=Comparable Sales.docx"
should be
"attachment; filename='Comparable Sales.docx'"
What is the desired workflow? Is the docx in the database or is it to be
created? How?
