I have a checkbox that is not tied to a model. Basically, here’s what
the beginning looks like in the view:
<% for entrant in @entrants %>
<tr class="<%= cycle(“even”, “odd”) %>" >
checked = “false”) %>
This submits to a controller action that has only the following line:
@firstnames = params[:to_check]
I’m trying to display the results on the next page:
<% for firstname in @firstnames %> <br /> <%=h firstname %> <% end %>
This seems really simple. Right now it’s displaying every firstname in
the array whether it was checked or not. I tried another way and it
only returned the first element in the array (so the names overwrote
each other). How do I check in the controller action method to see
which ones were checked? I’m coming from a Java web background and am a
beginner with Ruby on Rails and have been Googling extensively, but I’m
not understanding the examples, and the two recent Rails 2 books I have
(one in PDF form) are confusing me as well.
I tried to figure out how to use check_box_tag as well in case that’s
more appropriate in this case, but I’m just not sure what to do. How
should I change the form code and the controller so that I can retrieve
only the firstnames that were checked? The HTML checkboxes should only
send up the firstnames when checked.
Thanks so much!
