Rails Subdomain for nested resources - ruby-on-rails

Question

I've got a Rails 4 app that I'm trying to reconfigure to use subdomains for jobportals. Right now the root path for each portal is /jobportals/:id. What I want is for a user to be able to go to client.example.com and hit that root path. Then for example, if the user edits their profile, the url would be client.example.com/user/edit rather than www.example.com/jobportals/:id/user/edit.
I followed this ASCIIcasts tutorial on setting up subdomain routing, but it's not working for me. When I go to http://client.lvh.me:3000/, I am hitting the root_path of my Rails app, rather than the root_path for the portal.
I think the problem is that Constraints(Subdomain) isn't working with resources :jobportals. How can I reconfigure my routes to accomplish what I'm after?
MyApp::Application.routes.draw do
devise_for :users, :controllers => {:registrations => "registrations"}
root 'general#home'
get '/about' => 'general#about'
get '/team' => 'general#team'
get '/careers' => 'general#careers'
get '/terms' => 'general#terms'
get '/privacy_policy' => 'general#privacy_policy'
constraints(Subdomain) do
resources :jobportals, controller: 'portals/general' do
member do
root 'portals/general#home'
devise_scope :user do
get '/user/sign_in' => 'portals/sessions#new'
post '/user/sign_in' => 'portals/sessions#create'
delete '/user/sign_out' => 'portals/sessions#destroy'
post '/user/password' => 'portals/passwords#create'
get '/user/password/new' => 'portals/passwords#new'
get '/user/password/edit' => 'portals/passwords#edit'
patch '/user/password' => 'portals/passwords#update'
put '/user/password' => 'portals/passwords#update'
post '/user' => 'portals/registrations#create'
get '/user/sign_up' => 'portals/registrations#new'
get '/user/edit' => 'portals/registrations#edit'
patch '/user' => 'portals/registrations#update'
put '/user' => 'portals/registrations#update'
delete '/user' => 'portals/registrations#destroy'
end
get '/jobs' => 'portals/general#jobs'
get '/companies' => 'portals/general#companies'
get '/alljobs' => 'portals/general#alljobs'
resources :applications, controller: 'portals/applications'
get ':id' => 'portals/companies#profile'
get ':id/jobs' => 'portals/companies#jobs'
get ':id/jobfunctions' => 'portals/companies#jobfunctions'
end
end
end
end
Working Code Below
MyApp::Application.routes.draw do
devise_for :users, :controllers => {:registrations => "registrations"}
root 'general#home'
get '/about' => 'general#about'
get '/team' => 'general#team'
get '/careers' => 'general#careers'
get '/terms' => 'general#terms'
get '/privacy_policy' => 'general#privacy_policy'
constraints(Subdomain) do
get '/' => 'portals/general#home'
devise_scope :user do
get '/user/sign_in' => 'portals/sessions#new'
post '/user/sign_in' => 'portals/sessions#create'
delete '/user/sign_out' => 'portals/sessions#destroy'
post '/user/password' => 'portals/passwords#create'
get '/user/password/new' => 'portals/passwords#new'
get '/user/password/edit' => 'portals/passwords#edit'
patch '/user/password' => 'portals/passwords#update'
put '/user/password' => 'portals/passwords#update'
post '/user' => 'portals/registrations#create'
get '/user/sign_up' => 'portals/registrations#new'
get '/user/edit' => 'portals/registrations#edit'
patch '/user' => 'portals/registrations#update'
put '/user' => 'portals/registrations#update'
delete '/user' => 'portals/registrations#destroy'
end
get '/jobs' => 'portals/general#jobs'
get '/companies' => 'portals/general#companies'
get '/alljobs' => 'portals/general#alljobs'
resources :applications, controller: 'portals/applications'
get ':id' => 'portals/companies#profile'
get ':id/jobs' => 'portals/companies#jobs'
get ':id/jobfunctions' => 'portals/companies#jobfunctions'
end
end

It is looking like constraints are not define properly, it is something like get 'jobportals', constraints: {subdomain: 'subdomain_name'}
