I'm trying to create dynamic select menus for my application. I have a
partial that is rendered by an action in my site controller after an
:onchange event is triggered. I'll post the three pieces of code and
the error I keep getting.
*_models.html.haml*
- if models
= collection_select :model_id, models, :id, :name, {:prompt => "Select
Model"}
*site_controller.rb*
def update_models
# update models in dynamic select boxes
make = Make.find(params[:make_id])
models = make.models
render :update do |page|
page.replace_html 'models', :partial => 'models', :object => models
end
end
*browse.html.haml*
.form_row
= form.collection_select :make_id, Make.find(:all), :id, :name,
{:prompt => "Select Makes"}, {:onchange => "#{remote_function(:url =>
{:action => "update_models"}, :with => "'make_id='+value")}"}
.form_row#models
= render :partial => 'models', :object => @models
And from my log:

Asked for a remote server ? true, ENV["FERRET_USE_LOCAL_INDEX"] is nil,
looks like we are not the server
Will use local index.
