Hi, i tried like this,
View page:
<%= collection_select(:question,:subject_id ,Subject.all, :id, :name )
%>
<%= observe_field ‘question_subject_id’,
:url => {:controller=>‘question’,:action => ‘subject_action’}, :with
=> ‘subject_id’ %>
Controller:
i tried checking if it comes to the controller… the controller method
is not even called. Please help me to find the mistake
def subject_action
render :update do |page|
page.alert “hello from update items call!!”
end
end
