Rails - Aug 2009 - How do I use fastercsv to just read the header row and not the whole file?

How do I use fastercsv to just read the header row and not the whole
file?

I need to read the header row first and not the whole csv file
initially in the web application so I can map the input csv columns to
the db columns. Once the mapping is complete, a rake task will than
process the whole file. I don’t want to read the whole file to save
processing time.

How do I just read the header row only? I am assuming this would give
me an array “row” and row[0] will be the first column header, row[1]
the second column header, and so on.

Any help would be appreciated.

Open the file using FasterCSV''s new method, read one line, and bail
out.
