Alphabetic letter based search

dakshayini · #1 March 25th, 2009, 10:02 AM

Hi,

i have list of alphabets from A to Z .if i click on any one letter that should give me all the name starting with that corresponding letter from the database and should be displayed in the same page.

if i use each letter as a link(link_to) i cant display them in the same page.

if i use link_to_remote i am not able to get the params value of the letter i.e...Which letter i clicked.. if anyone know about this plz give me a solution.

You could try Rails AJAX support to send the database results to a div within the same page. Or you could try using a partial.

Expand|Select|Wrap|Line Numbers

 <%= javascript_include_tag "prototype" %>

<div class="element_links">

<% for char in 'A'..'Z' %>

<%= link_to_remote( "#{char}",

                         :update => "content",

                         :char => char,

                         :url =>{:action => :alp_search }) %> </li>

                         <% end %> 

                         <div id="content"></div>

                    <p>

<ul>

This is my rhtml

and my controller is

Expand|Select|Wrap|Line Numbers

 def live_search

     puts 'live_search'

           @classifieds = Course.find(:all,:conditions => ["lower(course_name)like ?","%" + params[:search].downcase+ "%"])

           puts @classifieds

           if params['search'].to_s.size < 1

           render :nothing => true

           else

                if @classifieds.size > 0

                   render :partial => 'display', :collection => @classifieds

                   else

                   render :text => "<li>No results found</li>", :layout => false

                   end

                end

              end

So as per the code if i click 'A' i should get all the courses which starts from 'A' from the database but am not able to get the params value of search.

In the place of link_to_remote if i use link i can get the correct result in the other page..but i want to display result in the same page..
is there is any way to do this...

Try adding content to your content div, such as

Expand|Select|Wrap|Line Numbers

 <div id="content">

  <%= @content %>

</div>

Then, in your controller, set the content variable with the partial, like

Expand|Select|Wrap|Line Numbers

 def live_search

  #...code...

  @content = render_to_string(:partial => 'display', :collection => @classifieds)
 
  render :update do |page|

    page.replace_html 'content', @content

  end

end

This should then update the div with your partial using your data collection.
