ruby - rails show page not showing associated record in rails 4 -

i have groups , have members(links).

my show page group used list members.

this worked fine in rails 3

i upgraded rails 4 , else works list of @members doesn't show , don't see error. regular erb page (i also, separately, have page content loaded through ajax should list members , broken, i'm focusing on erb page now).

the log shows

started "/groups/49" 127.0.0.1 @ 2014-08-18 20:34:25 -0400 processing groupscontroller#show html   parameters: {"id"=>"49"}   group load (0.4ms)  select `groups`.* `groups` `groups`.`id` = 49 order group_name  limit 1    (0.5ms)  select count(*) `links` ('group_id')   cache (0.0ms)  select count(*) `links` ('group_id')   cache (0.0ms)  select count(*) `links` ('group_id')   rendered groups/show.html.haml within layouts/application (5.5ms) 

the link is: link_to 'members', group

the routes are:

resources :groups   resources :links # enables group/:id/link/new   collection     post 'order_links'   end  end  

the groups controller has following show:

def show   @group = group.find(params[:id])   @members = link.where(:group_id, params[:id]).order(:position)   respond_to |format|     format.html # show.html.erb     format.xml  { render xml: @group }     format.json { render json: @members }       end end    

and page has:

  %ul#sortable     - @members.each |loop|       = content_tag_for :li, loop         - construct_hyperlink(loop.url_address, loop.alt_text)         = sanitize @address_url         \- #{h @new_link_alt_text}              #{link_to 'details', link_path(loop), {"title" => loop.alt_text}}              #{link_to 'edit', edit_link_path(loop), {"title" => loop.alt_text}} 

that's bit hard read grant you, rest assured it's been working in rails 3 years in app :)

maybe problem getting information associated model?

you have typo in where clause. this:

link.where(:group_id, params[:id]).order(:position) 

should become:

link.where(group_id: params[:id]).order(:position)
