New to this, so bear with me.
Controller:
def show
@client = Client.find_by_permalink(params[:permalink])
@images = ClientImage.find_all_by_client_id(@client, :order => "id
ASC")
session[:client] = @client
if session[:image].blank?
session[:image] = @images[0]
end
end
def view_image
@image = ClientImage.find_by_id(params[:id])
session[:image] = @image
end
View:
<div id="content_top">
<%= image_tag url_for_file_column(session[:image], "image"), :alt
=>
@client.name %>
</div>
RJS:
page[:content_top].reload
I thought that reloading the div after changing the session variable out
would cause a new image to display, but it does nothing.

What button/link are you hitting that you want to reload the page with? What is the name of the function? What is the name of the view? What is the name of the controller? What is the name of the RJS file? Are you passing in info from the app to reload it?

> What button/link are you hitting that you want to reload the page with?This creates a list of all the images in the client_images table associated with that client. It appears just below "content_top". <ul id="client_image_list"> <% if @images.length > 1 %> <% @images.each_with_index do |image, index| %> <%= link_to_remote index + 1, { :url => { :action => ''view_image'', :id => image } }, { :href => url_for(:action => ''view_image'', :id => image ) } %> <% end %> <% end %> </ul>> What is the name of the function? What is the name of the > view? What is the name of the controller? What is the name of the > RJS file?Everything is under the Client controller. This all takes place under the ''show'' view and action, ''view_image'' is the action to cycle out images and is also the name of the RJS.> Are you passing in info from the app to reload it?Yes. The value of the image to be changed is passed to the session[:image] variable. The idea is that by default the image shown is the oldest one associated with that client. @image is stored in a session variable (session[:image]) and called in the image_tag at the top. If a link in the ul is clicked, the ID of the image is passed to the ''view_image'' action. The view_image action assigns this new image to the session[:image] variable and the RJS reloads the div ''content_top''. -- Posted via http://www.ruby-forum.com/. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
