Rails model associations and contollers/routes -

-

i have setup association have shows associated cities.

the relationship many shows 1 city.

i create new shows city

like such: mysite.com/cities/1/shows/new

i have setup models :

shows belongs_to :city  city has_many :shows

how setup city controller new shows action? how setup routes.rb this?

i've figured out

in routes.rb

resources :cities   resources :shows end

you use rule such :

match /cities/:id/shows/new => "shows#new"

and after, in new action in controller shows, preload city_id params[:id], 

def new     @show = show.new(:city_id => params[:id]) end
