handle a special foramt error when importing csv

Raimon Fs

hello,

I have to import lots of csv files, and sometimes, there's one with the
csv that is not quite good formatted, and Ruby send a:

CSV::IllegalFormatError in DadeController#import_file_data_ajax
CSV::IllegalFormatError

I'm trying to handle the error with

begin
# Exceptions raised by this code will
# be caught by the following rescue clause

... some code ...


rescue Exception
$stderr.print "IO failed: " + $!

... some code ...

raise


but the error/exception never raises ...

I tried with SystemCAllError, StandardError, Exception, ...

The error happens in:
/System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/lib/ruby/1.8/csv.rb:639:in
`get_row'

because the file hasn't the expected formatted, it's not a csv file, but
the file has an extension of csv, that's why I want to catch those
exceptions ...

thanks,

regards

rescue CSV::IllegalFormatError

thanks, I'll try that ...

I wasn't aware that I could simply catch those errors, beacuse I would
like a more general error, because I don't know in advance how many
errors I'm going to find ...
