create config/initializers/active_scaffold.rb
insert app/views/layouts/application.html.erb
insert config/locales/en.yml
gsub app/views/layouts/application.html.erb

Generate active scaffold for resource city & zone

rails g active_scaffold City name:string

invoke active_record create db/migrate/20110408123206_create_cities.rb
create app/models/city.rb invoke test_unit
create test/unit/city_test.rb
create test/fixtures/cities.yml
route resources :cities do as_routes end
invoke active_scaffold_controller
create app/controllers/cities_controller.rb
create app/helpers/cities_helper.rb invoke test_unit
create test/functional/cities_controller_test.rb
create app/views/cities
rails g active_scaffold Zone name:string city:references

invoke active_record create db/migrate/20110408123531_create_zones.rb
create app/models/zone.rb invoke test_unit
create test/unit/zone_test.rb
create test/fixtures/zones.yml
route resources :zones do as_routes end
invoke active_scaffold_controller create app/controllers/zones_controller.rb
create app/helpers/zones_helper.rb
invoke test_unit create test/functional/zones_controller_test.rb
create app/views/zones

Add Associations

class City < ActiveRecord::Base
end

class Zone < ActiveRecord::Base
belongs_to :city
end

class City < ActiveRecord::Base
has_many :zones
end

Migrate database

rake db:create

rake db:migrate

    C:\proj\keyman>

    • Above command actually goes to jQuery site to download dependency files. It might be the case that you don’t have Internet connection or slow connection problems.

      If problem persists try to manually copy required files.

        Thanks for the quick reply Sandip!

        I think that this is maybe something else, even though it is in the timeout method. Note the error message:

        certificate verify failed (OpenSSL::SSL::SSLError)

        Also, my internet connection is great. Also, I could download the files – which ones? Where do I find them, and do they all go into public/javascripts?
