Hi, I am using the link_to_remote helper to call an action using and XMLHttp request. The action method has a call to render another action if a condition is met: if session[:prebooking].start_date != nil render :action => ''check_rate'' end the condition is being met, i.e. I checked that ''session[:prebooking].start_date != nil'' is in fact true, but program fails to render ''check_rate''. Is this because I am using a HTTP post request to call the action? How do I get ''check_rate'' to render if the condition is met? Thank you!

If it renders what you expect, the bug is in your condition, not the rendering. -- Posted via http://www.ruby-forum.com/. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

For example, do you have an :update in your link_to_remote? Maybe the rendering is just getting thrown away.

What should I store in this value because I don''t want to update a partial, I want to render a different action if this specific condition is met.

Since you don''t have an :update, the browser assumes what you have rendered is javascript (btw I find FireBug absolutely essential for doing this kind of thing) You can''t quite do what you want to do with link to remote. With link to remote you either : -generate some javascript (via rjs or render :update) that is run when the response is returned to the browser - include an :update parameter, the content of the specified element on the page is replaced with whatever you render There isn''t a specific replace the whole page - although you could of course pass an :update that effectively does that.

Here''s what I came up with:
<%= link_to_remote @current_two_months[0][days_in_first_week].date.mday,
:url => {:action => ''start_date'', :id => day},
:update => "month" if
@current_two_months[0][days_in_first_week].date.wday == i &&
session[:prebooking].end_date == nil%>
<%= link_to @current_two_months[0][days_in_first_week].date.mday,
{:action => ''check_rate'', :id => day} if
@current_two_months[0][days_in_first_week].date.wday == i &&
session[:prebooking].end_date != nil%>
This way a XMLHttp post link is created if the user has not already
selected an end_date for their vacation stay. However, if the user has
already selected the end_date using javascript on the second calendar,
the application will move forward in the process using a standard get
link and vise versa. By the way, after updating the session data, with
either the start_date or end date, the link_to_remote method is set to
update the months partial so that the the AJAX links are replaced with
get requests.
Best Regards,
Sam Woodard
