Multiple buttons pointing to single Controller Action

I am making an app where user can print a doc in either PDF or JPG format, using wicked-pdf and imgkit respectively. I have two buttons, one for PDF and other JPG. Is it possible to have these buttons point to same action in controller which here is 'create'. my buttons are as-

<%= button_to "Print Bill[PDF]", :action => "create" %>

<%= button_to "Print Bill[JPG]", :action => "new" %>

can i make both the actions create? if yes, how so? How to catch which button is hit and render the respective view.

First of all, it is generally recommended to use route helpers, rather than specify controllers and actions. So your code could be

<%= button_to "Print Bill[PDF]", bill_print_path(@bill, format: :pdf) %>
<%= button_to "Print Bill[JPG]", bill_print_path(@bill, format: :jpeg) %>

and in your controller

def print
    # insert here code to find your bill and load it from DB
    respond_to |format| do
        format.jpeg do
            # code to produce the jpeg version of the bill
        end
        format.pdf do
            # code to produce the pdf version of the bill
        end
    end
end

As a final step I would change button_to to link_to and style your link as a button, but that is more of a personal preference.
