Question

I would like to know how can I pass a ruby variable inside an observe_field method.

I have the following:

<% action_parameter = params[:action] %>

<%= observe_field :car_type,
                  :url => { :controller => 'cars',
                            :action => :display_subtypes },
                  :with => "'id=' + value + '&somevalue=' + action_parameter"
%>

‘action_parameter’ is a variable and I would like to pass its value in the observe_field method but the code above does not seem to work.

Any suggestion?

Answer 1

try this
<% action_parameter = params[:action] %>

<%= observe_field :car_type,
                  :url => { :controller => 'cars',
                            :action => :display_subtypes },
                  :with => "'id=' + value + '&somevalue=#{action_parameter}'"
%>
