Thanks a tonn saideep for your time and your help. It works great now
but 1 confusion, actually there are many..lol
1) the :with key in the observe_field, what does it takes and its use?
Suppose I got combobox displaying camp_location column from the table
and values as it primary key wich is id. Here :with key takes the value
of the selected location?
2) I gave :with=>"id" and in the controller, I tried:
Campsites.find(:all, :condition=>["walk_id = ?",params["id"]]) but
didn't work but using Campsites.find_by_sql("select * from campsites
where walk_id = "+params["id"]) did the work. I wonder why?
3) Does it matter to do "id" or :id. For example
....:update=>:campsites.... <div id = "campsites"> and vice-versa.
4) observe_field, does it use AJAX? coz it only updates the certain area
of the page and if it does, don't I have to insert
<%=javascript_include_tag :defaults%>
Thanks..
regards,
jay
