OK, so I''m an absolute noob at Ruby on Rails. I''ve read a lot of information I can find about form_for and most of them use form_for to create new items that get saved into the database and can be viewed later to edit, destroy, etc. In this case, the database will fill up with whatever the user wrote and I just want my program to have no information stored. I''ve been trying to take a user''s input from the text_field or file_field and once they hit the "submit" button, they get redirected to another page that, for instance, says "You wrote: [insert user input here]" I''ve been having no luck whatsoever doing this except to use HTML form, but I was hoping I can do this in Ruby on Rails.

Did you check the html to see if it is what you expect? I think it should be :action = ''to'' rather than :to Also when things are not working as you expect the log file (log/development.log) can often be useful in analysing the problem.

I think you may find that there is a </form> where you do not expect it, (separate from the one you have manually added). Looking at your code you have got the use of form_tag wrong.
