exception - Rescue won't rescue in Rails -


i'm writing simple app processes posted csv files , testing against invalid input (e.g. non-csv files). i'm using csv::reader.parse command parse csv in controller method, follows:

@parsed_file = csv::reader.parse(params[:file]) rescue []

however, despite rescue statement, i'm still getting uncaught csv::illegalformaterror when improper submissions entered. missing here?

thanks!

you need pass file handle parse:

@parsed_file = csv::reader.parse(file.open(params[:file], 'rb')) rescue []
