Ruby on Rails : how to implement Cancel button in form_tag

Question

I have a basic form using the form_tag helper working fine, but I want to add a cancel button, what is the syntax for doing this? I want the cancel button to appear as a button

Answer 1

button_to seems a simple way to achieve the same, but it has to be put outside of the form itself, but that can easily be fixed with css.

Also, to solve this in a more generic way (also working for editing nested resources on a resource that has not been persisted yet), you can create a separate form for the cancel that contains all the original values as hidden fields.
