am not using LOAD helper. Maybe i should.
this is my html
<div class="btn-group" style="margin-bottom: 20px; margin-top: 10px;">
{{=A(T('Report'), _class='btn btn-primary',
_href=URL('script','excelExport', args = request.args[0]))}}
</div>
And my controller code which at the end
data = open(tmpfilename,"rb").read()
os.unlink(tmpfilename)
response.headers['Content-Disposition']='attachment;filename=%s.xlsx' %
(fleName)
response.headers['Content-Title']=fleName
return data
Do you suggest another approach. I want to serve excel file
Thank you
