Hello All,
I have problem with select_tag and observe_field. I get following error
" NoMethodError in Businesses#plan_pricing
Showing app/views/businesses/_refresh_subscription_types.html.haml where
line #1 raised:
You have a nil object when you didn''t expect it!
You might have expected an instance of Array.
The error occurred while evaluating nil.collect"
following is source code
---------------------------------------------------------------------------------
code for "_plan_pricing.html.haml"
= error_messages_for :business
#plan_picker
- form_for :business, @business, :url =>
polymorphic_path(@business), :html => {:class =>
''MainForm''} do |f|
= select_tag ''plan_id'',
options_for_select(Plan.find(:all).collect {|plan| [ plan.title, plan.id
] })
= observe_field(''plan_id'', :url => {:controller
=> ''users'',
:action => :refresh_subscription_types }, :update =>
:refresh_subcription_types, :with => "''plan_id='' +
$(''plan_id'').value")
%span#refresh_subcription_types
= render :partial =>
''businesses/refresh_subscription_types'', :layout =>
''false''
%p= submit_tag :next_page.l
-------------------------------------------------------------------------------
code for "_refresh_subscription_types.html.haml"
= select_tag ''subscription'',
options_for_select(@subscription_types.collect {|subscription_type| [
subscription_type.title, subscription_type.id ] })
--------------------------------------------------------------------------------
code in "controller"
def refresh_subscription_types
@subscription_types = SubscriptionType.find(:all, :conditions =>
{:plan_id => params[:plan_id]})
respond_to do |format|
format.html {
render :partial =>
''businesses/refresh_subscription_types'',
:layout => ''false''
}
end
end
Here i get "@subscription_types" object nil , when I render
"_plan_pricing.html.haml" first time.
Please tell me where i am doing wrong.
Thanks,
Vikas.

If you don''t want it to use a layout you need to say :layout => false (ie the value false rather than the string ''false'') Fred

You might have expected an instance of Array.

You have brackets on your inner method, but not your outer method, so ruby requires you put brackets all around everything. This is, at least, my guess. Try this: <%= select_tag(''subscription'', options_for_select(@subscription_types.collect{|subscription_type| [subscription_type.title, subscription_type.id]})) %> Julian. ---------------------------------------------- Learn: http://sensei.zenunit.com/ Last updated 20-May-09 (Rails, Basic Unix) Blog: http://random8.zenunit.com/ Twitter: http://twitter.com/random8r> thanks > -- > Posted via http://www.ruby-forum.com/. > > >--~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
