whats wrong here? I get the same result of each item..

I get the same result off.png for each amigo.jid that I sent to 
isonline. were it should be on.png or off.png


this is in the view..
<table>
<tr>
    <th colspan="4">My Friend''s JID''s
</th>
</tr>

<% @amigos.in_groups_of(2, false) do |grupo| %>

        <tr class="<%= cycle(''odd'',
''even'') -%>">
        <% grupo.each do |amigo| %>
                <td><%= image_tag isonline(amigo.jid), :alt =>
"Status"
%></td>
                <td><%= amigo.jid  %></td>
         <% end %>
        </tr>
     <% end %>
</table>


this is in my helper:

def isonline(amigo)
                @isonline = nil
                @online = Status.find(:all, :select => "status", 
:conditions => { :"collection-owner" => "#{amigo}" })

                if @online == "online"
                        @isonline = "on.png"
                else
                        @isonline = "off.png"
                end

        end

will retrieve the status col from status. But @online is still
an ActiveRecord object.

So your condition

should be

if @online.status == "online

You also don''t need the quotes around amigo -
:"collection-owner" =>
amigo would work just as well

Re: whats wrong here? I get the same result of each item..

Hi guys, thanks, I got it to work on the console..
but when I do it from the app is not working..
it says I am sending a NIL, when I hard code a username then it works.. 
so it has to be the way I sent the variable from the view.
<% @amigos.in_groups_of(2, false) do |grupo| %>

        <tr class="<%= cycle(''odd'',
''even'') -%>">
        <% grupo.each do |amigo| %>
                <td><%= image_tag isonline(amigo.jid), :alt =>
"Status"
%></td>
                <td><%= amigo.jid  %></td>
         <% end %>
        </tr>
     <% end %>
</table>

whats wrong with isonline(amigo.jid) ???
amigo.jid works just fine in the next line..

Re: Re: whats wrong here? I get the same result of each item

your amigo.jid is fine. but your helper isnt fine.


def isonline(amigo)
    @isonline = nil
    @online = Status.find_by_collection_owner(amigo, :select => 
"status")

    if @online.status == "online"
       @isonline = "on.png"
    else
       @isonline = "off.png"
    end

end



please remember that you use find :all, it means that the result would 
be array, when you need to see the result of each array you should 
describe index key like @online[0] or @online[1] like that. Look your 
code :
> @online = Status.find(:all, :select => "status",
>        :conditions => { :"collection-owner" =>
"#{amigo}" })
> 
the result would be @online[0].status, please understand carefully find 
:all is diferent with find(id) <-- it will show you hashing.

>   Hi, yes I know I did changed my helper.. this is what I have now.. I 
also added just now to check for nil in case some records have problems..

module RosteritemsHelper
        def isonline(amigo)
                @online = Status.find(:first, :select => "status", 
:conditions => { :"collection-owner" => amigo })
                unless @online.nil?
                if @online.status  == "online"
                        @isonline = "on.png"
                else
                        @isonline = "off.png"
                end
          end
        end
end

Re: whats wrong here? I get the same result of each item

I tested your script like below and it works :

module RosteritemsHelper

def isonline(amigo)
  @online = Status.find(:first, :select => "status", :conditions
=> {
:"collection-owner" => amigo })

  if @online != nil && @online.status  == "online"
     @isonline = "on.png"
  else
     @isonline = "off.png"
  end

end

Remember to save both of your image in /public/images. I tested script 
above and really working fine.
