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")
%>" >
<td><%= check_box ("to_check", entrant.firstname,
{},
checked = "false") %></td>
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!

I had seen that, but it''s not clear to me (and some of the people who commented on there agree with me). As I said, my checkboxes are not tied to a model.

As I find somewhere on the net:
View (as many times as needed):
<input id="item_selected_keywords"
name="selected_keywords[]"
type="checkbox" value="exterior" />
Controller:
selected_keywords = params[:selected_keywords]
@item.keywords = selected_keywords.join(" ")

Actually, I wanted the results in a collection or array to iterate over in my next view, so this is what worked for that last line in the controller: @item.keywords = selected_keywords I was just trying really hard to use the Rails view helpers for a checkbox, but if I have to use straight HTML, then by no means am I opposed. It just seems like one of those Rails helpers should work for me, but I figure it''s because I don''t understand them and when I look at the examples in the API docs, they don''t seem to be applicable for my case (or I just don''t get them).
