trying to get wicked routes to work

assets_controller.rb

...
if @asset.save
  redirect_to team_asset_asset_steps_path(@team, @asset)
  # redirect_to team_path(@asset.team), :notice => "Your media was saved."
else
...

routes.rb

  resources :teams, :path => '', :except => [:index] do
    ...
    resources :assets, :path => '' do
      resources :asset_steps
      ...
    end
  end

terminal output

ActiveRecord::RecordNotFound (Couldn't find Asset without an ID):
  app/controllers/asset_steps_controller.rb:6:in `show'

is this what you meant?
team_asset_asset_step_path(:team_id => @team.id, :asset_id => @asset.id, :id => "files")

yep, something along those lines should work. Just run rake routes to make sure you're using the right helper. I might suggest chaining your wizard controller to be named something else like "builder" or something along those lines so it would be team_asset_builder_path.
