From the question you have posed, and the information you have provided, there is not a simple 'do this' answer. You need to get a bit further down the path of what you want to achieve. (unless someone knows some magic foo that I am unaware of).
1. How is the page update going to take place when I extend the contents.
eg. - replace the whole page each time the list updates
or - replace the list section
or - add additional items at the end
Do I let the page size continue to grow indefinitely or do I remove some items from the other end.
2. If I am going to manage addition/deletion of items. The items will probably be best structured in an an html list or table, and each may need a unique id, or can I just append/prepend to the list of items.
3. What mechanism will I use to identify the next 'page' of items I want to add to the list.
4. How is my controller going to get the correct list of items to add? ie what paging mechanism am I using.
5. How am I going to handle the ajax response that contains the items. I am going to need some js code to append/prepend or insert the items into the list.
6. What form will my response be in. I can send some javascript using an erb template to insert the items, or I could have a js function on the browser side ready to handle the response (eg as a success callback handler.) Or I could return data as json and handle the paging more fully in the browser js.
7. Finally having thought about all this, I would do some googling to see if someone has already implemented such a thing in a form I could learn from, or is there maybe a js library that might already provide most of the functionality I require.
I am sorry this is not a direct answer, but hopefully it may help to clarify what you are trying to achieve and how you are going to go about it.

Hi there i have this issue I have a view that render a partial for each
member inside the object @foo and I have a function for infinite scroll
so the server will be doing request after request while scrolling down
but I don't know exactly how to make this work here is some of my code:
def popular
@foo = Foo.new
respond_to do |format|
response = @foo.popular
...
flash[:notice] = "Welcome."
format.html { render popular_foo_path}
....
end
end
end
views/foo/popular
- @foo.each do |f|
= render(:partial => "popular_foo", :locals => { :foo => f})
views/foo/_popular_foo
- f['thumbs'].each do |thumb|
= image_tag(thumb['thumburl'].to_s, :alt => "thumb", :class =>
"thumb-popular")
every time you scrolldown to certain height a fuction
$(document).infinite_scroll is called and i have it configured to make a
new call to the method popular and I can see in the console and in the
firebug that it do the request and succeed but it won't render the next
results.
