Hai Bala,
I hav looked into the development.log file.I understood that the
problem as in "_current_readings_list" it is not getting the id
parameter based on which it has to display the readings.I dont know
whether i am correct or not.
I am attaching the development.log file.
controller
def show_readings_for_station
@range=ConfigureParameter.find(:all)
if (params[:state] =="")
@readings = CurrentReading.find(:all)
else
stations = Station.find_all_by_state(params[:state])
@readings = CurrentReading.find_all_by_station_id(stations,
:order=>"station_id")
end
respond_to do |format|
format.js
end #End of respond_to do block
end #End of action show_readings_for_station
def show_current_readings
@range=ConfigureParameter.find(:all)
if (params[:state] =="")
@readings = CurrentReading.find(:all)
else
stations = Station.find_all_by_state(params[:state])
@readings = CurrentReading.find_all_by_station_id(stations,
:order=>"station_id")
end
render :update do |page|
page.replace_html :current_reading,
:partial=>'current_readings_list'
page.visual_effect :highlight, 'current_reading'
end
end
index.html.erb
<% form_for :selected_district ,:url => {:action =>'update',:id =>
@selected_district } do |f| %>
<center><b> <%= f.label :Stations %></b>
<%= select(:selected_district,:state,
@states,{:include_blank=>'All'},{:onchange
=>remote_function(:url=>"/readings/show_readings_for_station",:with
=>"'state='+this.value")} ) %>
</center>
<%end%>
<div id="reading_list">
<% form_tag :action =>"details" do %>
<div id="current_reading">
# code here
</div>
<%= periodically_call_remote(:url => { :action=>
"show_current_readings" }, :frequency => 5)%>
<%end%>
</div>
Can you plz tell me how can i get the id of the selected element in
select tag to the action "show_current_readings"? If i am wrong plz do
correct me..
Thanks,
Veena
