Question

I’m trying to add a “preview” button/page to my app.

Is there a way to add a different value to both my “post” and “preview” submit buttons that get passed in the params hash so that I can check which one was pressed in the controller and render the view accordingly?

Is this the best way to do this?

Answer 1

The keys of the params hash are just the name value of an element.

If you had two buttons named “submit”, one with value="post" and value="preview", then you could do something like:

if params[:submit] == "preview"
