hi i have a table called Streams with columns name,resolution,codecname,framerate. i have tags to the table entries if streams.like 1920x1080,aac,mpeg2...
now i have to search the table entries for tag entered in the search box. once i enter the tag name in the search box entry i m getting errors like:
Unknown action No action responded to get_results
can help me in this issue?
to do that i have added below codes in;
1)index.html.erb
Search: <input type="text" id="search_form" name="search" />
<img id="spinner" src="/images/indicator.gif" style="display: none;" /> <div id="results"></div> <%= observe_field 'search_form', :frequency => 0.5, :update => 'results', :url => { :controller => 'streams', :action=> 'get_results' }, :with => "'search_text=' + escape(value)", :loading => "document.getElementById('spinner').style.display='inline'", :loaded => "document.getElementById('spinner').style.display='none'" %>
2)streams_controller.rb
def get_results if request.xhr? if params['search_text'].strip.length > 0 terms = params['search_text'].split.collect do |word| "%#{word.downcase}%" end #@streams = Stream.find( # :all, # :conditions => [( ["(LOWER(name) LIKE ?)"] * terms.size ).join(" AND "),* terms.flatten])
#addded for listing the streams with a tag assigned
@streams = Stream.find_tagged_with(params[:search_text]) #@streams = Stream.find_tagged_with(params[:terms]) end render :partial => "search" else redirect_to :action => "index" end end
3)in layouts :streams.html.erb
<html> <head> <title>Streams</title> <%= javascript_include_tag :defaults %> </head> <body> <%= yield %> </body> </html>
4)created _search.html.erb for results:
<% if @streams %> <ul> <% for stream in @streams %> <li> <%= h(stream.name) %> </li> <% end %> </ul> <% end %>
thanks srikanth
