ruby on rails - ArgumentError in mongoid-rspec -


when bundle exec rspec spec/controllers got:

/var/lib/gems/1.9.1/gems/rspec-core-3.0.4/lib/rspec/core/hooks.rb:521:in `extract_scope_from': must explicitly give scope (example, context, suite) or scope alias (each, all) when using symbols metadata hook. (argumenterror)

my gemfile:

gem 'rails', '4.1.4' gem 'mongoid', '~> 4', github: 'mongoid/mongoid' gem 'sass-rails', '~> 4.0.3' gem 'uglifier', '>= 1.3.0' gem 'coffee-rails', '~> 4.0.0' gem 'jquery-rails' gem 'turbolinks' gem 'jbuilder', '~> 2.0' gem 'sdoc', '~> 0.4.0',          group: :doc gem 'spring',        group: :development group :development, :test     gem 'rspec-rails', '~> 3.0.2' end  group :test     gem 'database_cleaner'     gem 'factory_girl_rails'     gem 'mongoid-rspec' end

my spec_helper.rb:

# spec_helper.rb  env["rails_env"] ||= 'test' require file.expand_path("../../config/environment", __file__) require 'rspec/rails'  # requires supporting ruby files custom matchers , macros, etc, # in spec/support/ , subdirectories. dir[rails.root.join("spec/support/**/*.rb")].each {|f| require f}  rspec.configure |config|   config.mock_with :rspec    config.before :each     mongoid.purge!   end    require 'database_cleaner'   config.before(:siute)       databasecleaner.strategy = :truncation       databasecleaner.orm = "mongoid"   end    config.before(:each)       databasecleaner.clean   end end

my rails_helper.rb

# file copied spec/ when run 'rails generate rspec:install' env["rails_env"] ||= 'test' require 'spec_helper' require file.expand_path("../../config/environment", __file__) require 'rspec/rails'  dir[rails.root.join("spec/support/**/*.rb")].each { |f| require f }  rspec.configure |config|    # argumenterror whether following commented out or not   config.infer_spec_type_from_file_location! end

my spec/controllers/typer_controller_spec.rb (only file in controllers folder)

require "rails_helper"  rspec.describe typercontroller, type:controller     describe "get #index"         "initializes properly"             :index             # nothing test yet         end     end end

you have syntax error here

rspec.describe typercontroller, type:controller

change to

rspec.describe typercontroller, type: :controller

python - Django-cities exits with "killed" -

i trying install django-cities on server 500mb ram. whenever run: manage.py cities the system exits saying killed. trying run: manage.py cities --import=country --force worked, guessing matter of running out of memory. to bypass, tried refer package local copy of cities' data file. still didn't work. any ideas on how can migrate data without having increase memory on server? based on suggestion comments, solved setting temporary swap file. if unfamiliar it, can follow these steps: set swap file touch /var/swap.img chmod 600 /var/swap.img set swap file size cd /var dd if=/dev/zero of=/var/swap.img bs=1024k count=1000 this create 1gb swap file. prepare disk image mkswap /var/swap.img activate swap memory swapon /var/swap.img once done, can turn off swap image: swapoff /var/swap.img more information on virtual memory , swap files can found here: https://www.digitalocean.com/community/tutorials/how-to-configure-virtual-me...
