i am currently having a very strange problem with observe_field. i have a select box that looks like this:><%= select "product_section", "section", ProductSection.find(:all, :order => "title ASC").collect { |p| [p.title, p.id]}, { :include_blank => true } %>i want to observe the drop down box to have an action happen whenever the value of the dropdown is changed.. i have added the following code to observe the field: <%= observe_field(:product_section_section, :update => ''attribute_data'', :url => ''insert_attributes'', :frequency => 1) %> notice the naming of the field_id in observe field. this does work.. the problem is, when i make a selection, the parameters that get passed look like this: params = {"7"=>nil, "authenticity_token"=>"f245fed70e1760739566121d68a8340a154e086a", "action"=>"insert_attributes", "controller"=>"admin"} that key/value of "7"=>nil is the one i am interested in.. but it seems like it''s backward. i am thinking i should get a key/value passed that looks more like: ''"product_section"=>"7"'' anyone have any idea what i am doing wrong? thanks! -- Posted via http://www.ruby-forum.com/.
just as a hint..
when i submit this form, the select box value looks like this:
"product_section"=>{"product_section_id"=>"3"}

You can omit frequency if u just want to trigger on change. To pass arbitrary parameters use the :with option like described in the rails api for link_to_remote. I would be more specific if i weren''t on my cell in berlin underground :) 2009/5/15, Sergio Ruiz <rails-mailing-list-ARtvInVfO7ksV2N9l4h3zg@public.gmane.org>:> > i am currently having a very strange problem with observe_field. > > i have a select box that looks like this: > >><%= select "product_section", "section", ProductSection.find(:all, :order >> => "title ASC").collect { |p| [p.title, p.id]}, { :include_blank => true } >> %> > > i want to observe the drop down box to have an action happen whenever > the value of the dropdown is changed.. > > i have added the following code to observe the field: > > > <%= observe_field(:product_section_section, :update => ''attribute_data'', > :url => ''insert_attributes'', :frequency => 1) %> > > > notice the naming of the field_id in observe field. this does work.. > > the problem is, when i make a selection, the parameters that get passed > look like this: > > params = {"7"=>nil, > "authenticity_token"=>"f245fed70e1760739566121d68a8340a154e086a", > "action"=>"insert_attributes", "controller"=>"admin"} > > > that key/value of "7"=>nil is the one i am interested in.. but it seems > like it''s backward. i am thinking i should get a key/value passed that > looks more like: > > ''"product_section"=>"7"'' > > anyone have any idea what i am doing wrong? > > thanks! > -- > Posted via http://www.ruby-forum.com/. > > > >-- Von meinen Mobilgerät aus gesendet
