Question

I want to create an extra radio button with some choices inside an existing rails form (I use simple_form gem). The problem is that I do not want this to point in any field in my model. I want it to be an extra field that I would like to pass.

All examples that I found introduces a hidden tag. But I do not want it to be hidden I want a radio button set.

Is that possible?

Answer 1

Try using radio_button_tag inside the modal form, I have used it in the past. An example would be:

radio_button_tag 'send_me_updates', 'radio', false

When you submit the form, I think you will be able to access the radio button value with params[:send_me_updates]. Should work, please try it and let me know.
