Question

My routes file is:

resources :countries do
  resources :regions do 
    resources :appartments
  end
end

models:

Country: has_many :regions

Region: belongs_to :country, has_many :appartments

Appartment: belongs_to: region

Region_controller:

def index
  @country = Country.find(params[:country_id])
  @regions = @country.regions
end


def show
  @country = Country.find(params[:country_id])
  @region = @country.regions.find(params[:id])
end  

Question:

I want to show appartments on the region page. What’s the best practice in my region controller?

Answer 1

It would simply be:

@appartments = @region.appartments
