Hi John, thanks.
You're right, I didn't past the method header because I thought it
didn't matter when the input filename is hardcoded.
The try/except isn't very helpful indeed so I commented it out.
You're right I wrongly referred to the UnicodeReader
class in my first post because that's ultimately where I want to go
so
I outcommented it here for you to see.
The fact is that neither csv.reader nor the UnicodeReader will read
the file, while writing with the UnicodeWriter
works like a charm.
That's why I put str() around roles to see any content.
I simplified the csv-file by cutting off columns without result. The
file looks now like:
id;company;department
12;Cadillac;Research
11;Ford;Accounting
10;Chrysler;Sales
The dictionary on the return is because this code is part of my
TurboGears application.
The entire method is:
import csv
from utilities.urw import UnicodeWriter, UnicodeReader
@expose(allow_json=True)
def import_roles(self, input=None, *args, **kwargs):
inp = 'C:/temp/test.csv'
roles = []
msg = ''
## try:
fp = open(inp, 'rb')
reader = csv.reader(fp, dialect='excel', delimiter=';')
## reader = UnicodeReader(fp, dialect='excel', delimiter=';')
for r in reader:
roles.append(r[0])
fp.close()
## except:
## msg = "Something's wrong with the csv.reader"
return dict(filepath=inp,
roles=str(roles),
msg=msg)
csv.reader results in: for r in reader: Error: line contains NULL
byte
Use of UnicodeReader results in: UnicodeDecodeError: 'utf8' codec
can't decode byte 0xff in position 0: unexpected code byte
Will post only complete code from now on thanks.
