Massimo, the strange behavior continues to occur...
I had to make a change and store the number of lines that the file has.
Added a function to the oncreate SQLFORM.grid as follows:
def set_total_emails(form):
print request.vars.file_name
form.vars.file_name = request.post_vars.file_name
sent_file = request.vars.file_name.file
file_name = request.vars.file_name.filename
extension_file = file_name.split('.')[-1]
if extension_file == 'csv':
import csv
file_lines = list(csv.reader(sent_file, delimiter=',',
quoting=csv.QUOTE_NONE))
elif extension_file == 'txt':
file_lines = list(sent_file.readlines())
db(db.files_uploaded.id == form.vars.id).update(total_lines =
len(file_lines))
If I do not enter the "print request.vars.file_name" I can not get the
total rows, it returns 0.
Note: web2py 2.7.2
Is there any other way I can do the same thing?
Thanks!!
