This should do
def excel_read():
result={}
if request.vars.filename != None:
try:
import xlrd
path=os.path.join
(request.folder,'private','a_dummy_file_name.xls')
open(path,'w').write(request.vars.filename.file.read())
book = xlrd.open_workbook(path)
result['The number of worksheets is']=book.nsheets
result["Worksheet name(s)"]= book.sheet_names()
sh = book.sheet_by_index(0)
result['sh.name']=sh.name
result['sh.nrows']=sh.nrows
result['sh.ncols']=sh.ncols
result['Cell D30 is']=sh.cell_value(rowx=29, colx=3)
for rx in range(sh.nrows):
result['row ' + str(rx)]=sh.row(rx)
except:
response.flash = T('excel_read exception')
return dict(result=result)
for you request.vars.filename is a cgi.FieldStorage object. It is not
a named file.
It containes
- request.vars.filename.file (a buffered input stream)
- request.vars.filename.filename (the original filename)
For you to access it you should read the stream and save it with a
name. Do not use the original filename to avoid directory traversal
attacks.
