CSV or FasterCSV? I saw that perhaps there were some issues with FasterCSV and csv files created from Mac versions of Excel. Anyone have any experience with this and can recommend a newbie friendly

installing fastercsv into vendor directory
I am using fastercsv to process input files. I want to install it into my app/vendor directory as a gem (I guess). I used ''rake rails:freeze:gems'' to get rails into the vender dir.

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. But 2 or more is completely beyond me. Any suggestions? Cheers, Nick --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups

Strategy for importing temporary .csv file?
For some reason, I''ve posted this question to this forum 4 times now and it never appears in the daily consolidated email I get daily? I''ve written a routine allowing the client user to declare where their .csv import file resides and then send it to the server to import the many rows into an existing model table, and then throw it away.

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:

why can't johnny download?
I''m working on an app that includes the feature to allow user to download a csv file of their data. I''ve got it working on my local machine, but when I deploy it, the link I''m making doesn''t work for doing the download. The file IS being created in the location I''m intending, but the file download only works on my local machine and not on the server.
