Rails - May 2007 - making a list of records refresh in order after a 'page.insert_html'

Hi Everyone,

I''m working through a book that demonstrates using Ajax to add a new
record to a category.  Just a single field, being a name is required.

I''ve applied it to a real app and it works OK except for one small
detail.

The add facility is on the same page as the list of existing
categories, & I made one change which is to display the existing
entries in name order. But when a new one is added it adds to the
bottom ( which is what it is told to do ), but I want the list to be
refreshed with the new item in it''s alphabetical position.

The only options for page.insert_html are: top, bottom, before and
after.

Here is the ''new'' def:

  def new
    @make = Make.new(params[:make])
    if @make.save
      return if request.xhr?
      render :partial => ''make'', :object => @make
    end
  end

Here is the rjs code:

if @make.new_record?
  page.alert @make.errors.full_messages.join("\n")
else
  page.insert_html :bottom, ''make_list'', :partial =>
''make''
  page.visual_effect :highlight, "make_#{@make.id}"
  page.form.reset ''make_form''
end

( note: The book is using a ''category'' table where my app is
using a
''make'' table )

Anyone know how to accomplish this ?

TIA - Dave Porter

You could assign each row (whether it be li, or dd, or tr) with their  
ID, and then in your ruby code find out where it should be, and  
insert below that. The only thing I can think of in these wee hours.

Thanks Zach,

Sounds a bit complicated for a newbie !  Not life threatening so I''ll
come back to it.
