Hi, I am looking for ideas on how to remove the last item from a paginated page when a new item is inserted, thus leaving only 10 elements on the page. Currently I have a form that inserts with AJAX, but as expected, each post added to the page just increases the number of posts leaving 11 on a page that should only be displaying 10. I have unique ID''s for each post (e.g. post_4, post_5, etc) and the post with the lowest number is on the bottom of the page, can anyone think of a way to make the last post disappear when the new post is added? Basically what i need to do is do a page.hide ''page_<% lowest id %>'' - where the lowest id is not a known integer. Ideas? ~Jamie

I''m no expert with Rails or Ruby (I''ve only been using it for
about a week),
but it sounds like you want to do something like this:
http://www.codyfauser.com/articles/2005/11/20/rails-rjs-templates
Cody adds an item to the list but its always the same. To change it you
could just pass the post details through the action then page.hide "
page_#{@lowest_id}" and then page.insert_html
"page_#{@newpost.title" or
something. (The syntax for insert_html isn''t correct, but you should
get the
idea)
Thought it might help! It probably won''t but that''s where
I''d start.

This is what I am already doing, I just need a way to get the ID of the last post so I can hide it when a new one is made. If I could get the ID of the lowest post on the page I would be able to do that. ~Jamie On Jul 14, 2006, at 7:59 PM, Chris Lloyd wrote:> I''m no expert with Rails or Ruby (I''ve only been using it for about > a week), but it sounds like you want to do something like this: > http://www.codyfauser.com/articles/2005/11/20/rails-rjs-templates > > Cody adds an item to the list but its always the same.

I guess I would save the scriptaculous overhead if I did it this way, but it seems like re-rendering everything would defeat the purpose of using ajax in the first place (avert unnecessary page-loads and provide a smooth UI). ~Jamie On Jul 14, 2006, at 5:20 PM, Kevin Olbrich wrote:> > On Friday, July 14, 2006, at 3:04 PM, Jamie Quint wrote: >> Hi, >> >> I am looking for ideas on how to remove the last item from a >> paginated page when a new item is inserted, thus leaving only 10 >> elements on the page. >> >> Currently I have a form that inserts with AJAX, but as expected, >> each post added to the page just increases the number of posts >> leaving 11 on a page that should only be displaying 10. >> >> I have unique ID''s for each post (e.g. post_4, post_5, etc) and the >> post with the lowest number is on the bottom of the page, can anyone >> think of a way to make the last post disappear when the new post >> is added? >> >> Basically what i need to do is do a page.hide ''page_<% lowest id %>'' >> - where the lowest id is not a known integer. >> >> Ideas? >> >> ~Jamie >> _______________________________________________ >> Rails mailing list >> Rails@lists.rubyonrails.org >> http://lists.rubyonrails.org/mailman/listinfo/rails > > You could just re-render the 10 items on the page and replace all > of them. > > _Kevin > > -- > Posted with http://DevLists.com.

When the controller saves the actual record, the instance variable
that contains the record should have the ID now.
@post = Post.new(params[:post])
@post.save
@last_post_id = @post.id
Then in the data loaded by the remote form you could simply:
Element.hide("post_<%= @last_post_id %>")
Hope this helps,
