Hi guys,
Am having a problem.
I have this def in my index controller that works like this:
def do_something
$a = variable1
$b = variable2
$c = variable3
$d = ""<script language=\"Javascript\"> \n new
Insertion.Bottom(''#{$c}'',
''#{$a} - #{$b}''); \n </script>"
$trigger = "1"
render(:partial => "do_something")
end
on my do_something.rhtml, my code is this:
<% if $trigger == "1" %>
<%=$d %>
<% $trigger = "0" %>
<% return %>
<% end %>
I get a render with no layout error message. What am I doing wrong?
thanks in advance!
Bing

What am I doing wrong?Just guessing, but is it because you have that ''return'' in your do_something.rhtml? David

What am I doing wrong?Partials should be named with a beginning underscore _do_something.rhtml More likely you want to just take the render(:partial => "do_something") out of your controller. The default is for every controller action that doesn''t redirect to render a template with the same name as the action, so the do_something action will render the do_something.rhtml template. If you want to specific a different template, use render(:action => "template_name") -- Ray
Hi David, I need the <%return%> on my rhtml so that I can exit out of my if condition. Hi Ray, Sorry, but yes, our render partial rhtml does have the underscore. so the page is called _do_something.rhtml. Just the same we had already used render(:action with no success. Also, if I may add, def do_something is being executed by a periodical_call_remote function. Bing -- Posted via http://www.ruby-forum.com/.

The main thing I guess is, I don''t see which section does the first render and which section does the 2nd render. there was no explicit statement in the code to make a second render. -- Posted via http://www.ruby-forum.com/.

You should be using instance @vars instead, the ones with the @ sign. -Ezra

So you have controller def periodical_call_remote_function do some stuff do_something What''s here? end def do_something some more stuff defining @thing render :action => ''do_something'' end view do_something.rhtml <% display @thing %> Do you have a periodical_call_remote_function.rhtml? -- Ray
Hi Ezra,
The reason I needed to use global variable for the def was because we
needed to pass the value of the variable to the rhtml. Setting it with @
doesn''t allow me to do that. We tested it again to make sure and true
enough, while variable c was $c, the values were being passed. When @c,
the values weren''t.
Hi Ray,
my periodical call remote is actually found on my rhtml with this line
of code:
<div id="divname"></div>
<%= periodically_call_remote(:update => ''divname'', :url
=> { :action =>
:do_something}, :frequency => 3 ) %>
So it calls do_something from there.
Still having the doublerender! If I tried putting on the
"erase_render_results", it doesn''t show the error but it also
doesn''t
show what I needed to render. It''s driving me nuts!
Regards,
Bing

When @c, > the values weren''t.You have to manage to make it work with @ then! afaik it''s really the way it should be done ( http://api.rubyonrails.com/classes/ActionController/Base.html) Could you post a repro of your issue with @ variables ? (maybe use longer variable names also). This way we may be able to understand what''s happening in there. Really, you shouldn''t use those global variables for this or you''ll get unexpected things ("I see dead people" and stuff :-) hth Thibaut -------------- next part -------------- An HTML attachment was scrubbed...
