I would like to change the form in view.html.erb based on user selection (launching either a jupyter notebook or R notebook). Is this possible?

You can use `conn_params`. The trick is to set an environment vairalbe that’ll be written back to the `connection.yml` file. Then if it’s in the `connection.yml` (like `password` or `host`) you can use it in the `view.html.erb`.

Thank you! I’ll give this a try.
