How do you use Ruby CSV converters?

Question

Suppose you have the following file:

textfield,datetimefield,numfield
foo,2008-07-01 17:50:55.004688,1
bar,2008-07-02 17:50:55.004688,2

The Rub

Answer 1

Your date times don't match the CSV::DateTimeMatcher regexp that CSV uses to decide whether it should attempt a date time conversion. By the looks of it it's doing so because of the fractional seconds you've got.

You could either overwrite that constant or write your own converter (DateTime.parse seems happy with your strings)
