I want to know how a part of the webpage (data obtained from
database) can be refreshed at periodic intervals(say 5 sec).
I have tried periodically_call_remote() method.But it is not working
for me.
<% periodically_call_remote(:url => { :action =>
:show_readings_for_station },
:frequency => 5, :update => "reading_list")%>
<div id="reading_list">
#my code here which obtains data from database
</div>
show_readings_for_station is a method in the controller.....
You need to render the periodical executer in the page, so two things
that should do it:
- Add the call to periodical updater after your div element
- use <%= instead of just <%
<div id="reading_list">
# render the partial here, render the same partial from your
show_readings_for_station method
</div>
<%= periodically_call_remote(:url => { :action
=> :show_readings_for_station }, :frequency => 5, :update =>
"reading_list")%>
