Most likely you have that content in your .rhtml files too Tauraus wrote: > It seems that @content\_for\_layout will contain all the content include > the part before ,how can it happen? very thanks! ---

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](http://127.0.0.1:3000/demands) or [http://127.0.0.1:3000/index](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](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 Tauraus wrote: > 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](http://127.0.0.1:3000/demands) or > [http://127.0.0.1:3000/index](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](http://122.0.0.1:3000/demands/list) > then everything is ok > > Can anybody tell me the reason? very thanksful!
