I tried to use option ":row_sep" but it did not work, it still uses the returns within the text field as end of row, too:

newbie wants to know..FasterCSV or just CSV?
I''m trying to grab a CSV file from a user and let them upload it directly to my database, but doing some minor checks on the data before saving. Which is the easier way to implement this?

Rails 3 & FasterCSV
I''m using FasterCSV to upload some csv files and create some records based off the data in the CSV files. I''m pretty sure the problem is a character encoding issue because the CSV is full of French and German words. If I remove all the accents off the letters, then it uploads fine, otherwise it just throws a FasterCSV::MalformedCSVError. jeremy-woertinks-imac:winovations

Multiple header rows with FasterCSV?
Hi, So I''m new to RoR and have been playing around with the FasterCSV gem. One thing I can''t figure out is how you get it to skip multiple header rows. I can do one row no problem.
