Hi,everyone:    I use form_tag create a form and nested a button_to tag like this:              <%= form_tag(orders_path) do %>                      ......... #some form fields                     <%=button_to "remove",line_item, :method=>:delete %>                     <%= submit_tag "Checkout" %>               <% end %>

  when I click "Checkout" ,the form always invokes "remove" method! How can I solve this problem? Thanks!

Have a look at the html of the page (View > Page Source, or similar, in the browser) and see what <form> tag you are generating. That will show you what action should be called. Also you can look in log/development.log to see what it says when you click submit.

Unless you have a good reason, however, I would suggest using form_for rather than form_tag. It makes life easier generally.

Hi,everyone:

I use form_tag create a form and nested a button_to tag like this:

         <%= form_tag(orders_path)  do %>

                 .........     #some form fields

                <%=button_to "remove",line_item, :method=>:delete

%>

                <%= submit_tag "Checkout" %>

          <% end %>

I’m not sure but I think button_to creates a form. Since button_to is inside

the form tag, and it creates a form, then clicking ‘Checkout’ will also submit

whatever is inside the form created by button_to.

Yes of course, good thinking Jim. Nested forms are not allowed in html.
