Upload File Using Form


I am trying to upload a CSV file through a form, process it, then input
the values in the file it into my database. So first step, I need to
upload the file. I created the form, uploaded a test file but I am
having trouble accessing the file in my controller. I can access a hash
but all contains is the original filename of the file. I guess my
question is how can I access this file and save it so that I can later
pass it to a CSV processing function. I assume the file is uploaded to
some sort of temp file? I am new at rails but I have accomplished
uploading and saving files in PHP before. Any help would be great.
