What is the matter with content_for_layout?

Rails
#1

Here is my layout file:

My Demands <%= stylesheet_link_tag 'ajax_scaffold', :media => 'all' %> <%= javascript_include_tag 'prototype', 'effects', 'rico_corner', 'ajax_scaffold' %>
<%= @content_for_layout %>

After I start up the Webrick server,the html source will be as follows:

My Demands
My Demands
...

It seems that @content_for_layout will contain all the content include
the part before ,how can it happen? very thanks!

Most likely you have that content in your .rhtml files too

I got the reason,but I still do not know how to resolve this problem.
It is because of my using pagination.
Here is the demands_controller:

def index
end

def list
@pages = Paginator.new self, Demand.count, 10, @params[:page]
@demands = Demand.find(:all, :order => ‘reply_times DESC’, :limit =>
10, :offset => @pages.current.offset)
end

Here is the index.rhtml:
<%= render_component :controller => ‘demands’, :action => ‘list’ %>
it is generated by the Ajaxscaffold.

if the url refers to : http://127.0.0.1:3000/demands or
http://127.0.0.1:3000/index
then the above error will happen
if the url refers to : http://122.0.0.1:3000/demands/list
then everything is ok

Can anybody tell me the reason? very thanksful!

OK, now it looks clear

layout is dublicated because it applied twice

you should put something like this in your controller
layout “your_layout”, :except => ‘list’

however, correct way of doing this would be removing index.rhtml and
changing index action to

def index
list
render :action => ‘list’
end
