XlsxWriter object save as http response to create download in Django?
回答1:
I think you're asking about how to create an excel file in memory using xlsxwriter
and return it via HttpResponse
. Here's an example:
try:
import cStringIO as StringIO
except ImportError:
import StringIO
from django.http import HttpResponse
from xlsxwriter.workbook import Workbook
def your_view(request):
# your view logic here
# create a workbook in memory
output = StringIO.StringIO()
book = Workbook(output)
sheet = book.add_worksheet('test')
sheet.write(0, 0, 'Hello, world!')
book.close()
# construct response
output.seek(0)
response = HttpResponse(output.read(), mimetype="application/vnd.openxmlformats-officedocument.spreadsheetml.sheet")
response['Content-Disposition'] = "attachment; filename=test.xlsx"
return response
Hope that helps.

A little update on @alecxe response for Python 3 (io.BytesIO instead of StringIO.StringIO) and Django >= 1.5 (content_type instead of mimetype), with the fully in-memory file assembly that has since been implemented by @jmcnamara ({'in_memory': True}) !
Here is the full example :
import io
from django.http.response import HttpResponse
from xlsxwriter.workbook import Workbook
def your_view(request):
output = io.BytesIO()
workbook = Workbook(output, {'in_memory': True})
worksheet = workbook.add_worksheet()
worksheet.write(0, 0, 'Hello, world!')
workbook.close()
output.seek(0)
response = HttpResponse(output.read(), content_type="application/vnd.openxmlformats-officedocument.spreadsheetml.sheet")
response['Content-Disposition'] = "attachment; filename=test.xlsx"
output.close()
return response

When it comes to Django, you can even do without the whole StringIO
shenanigans. HttpResponse
behaves just like a StringIO in that respect:
from django.http import HttpResponse
from xlsxwriter.workbook import Workbook
def your_view(request):
# your view logic here
# create the HttpResponse object ...
response = HttpResponse(content_type='application/vnd.openxmlformats-officedocument.spreadsheetml.sheet')
response['Content-Disposition'] = "attachment; filename=test.xlsx"
# .. and pass it into the XLSXWriter
book = Workbook(response, {'in_memory': True})
sheet = book.add_worksheet('test')
sheet.write(0, 0, 'Hello, world!')
book.close()
return response
Addendum: You need to specify {'in_memory': True}
or you might get HttpResponse has no attribute seek()
. Thanks @Jeb
