Hello, i need help. Devise + custom action in DeviseRegistrationController + dynamic select.

Either that should be f.collection_select or you need an extra parameter before :country_id

_locations.html.erb -------------------------- <p><%= label_tag :location %><br /> <%= collection_select (:location_id, locations, :id, :location_name, {:prompt => "Select an Location"}, {:onchange => "#{remote_function(:url => {:action => "update_cities"}, :with => "'location_id='+value")}"}) %></p> --------------------------

_cities.html.erb -------------------------- <p><%= label_tag :city %><br /> <%= collection_select(:city_id, cities, :id, :city_name, {:prompt => "Select a City"}) %></p> --------------------------

what to do with partials?

new error:

-------------------------- NoMethodError in Devise/registrations#new

You are still using the syntax for f.collection_select, but are just using collection_select. Check the docs for that method, you need an extra parameter before :location_id. See http://ap.rubyonrails.org/classes/ActionView/Helpers/FormOptionsHelper.html#M000455

def update_locations     # Обновляем области и города на основе выбранной страны     country = Country.find(params[:country_id])     locations = country.locations     cities = country.cities

    render :update do |page|       page.replace_html 'locations', :partial => 'locations', :object => locations       page.replace_html 'cities', :partial => 'cities', :object => cities     end   end

Have a look at the Rails Guide on debugging. Then set breakpoint in the view code just before the error and inspect the data to see if it all looks right. First though I would check the docs for collection_select and check that nil is valid as the first parameter. Note particularly in http://ap.rubyonrails.org/classes/ActionView/Helpers/FormOptionsHelper.html#M000455 the second sentence and what it says about the object parameter. I suspect you have another problem with one of the other params that is causing the map problem. Perhaps one of them is nil also.
