rake assets: прекомпиляция при попытке подключения к базе данных

Question

Я пытаюсь отладить, почему мое приложение пытается подключиться к моей базе данных, когда я запускаю rake assets:precompile --trace.

Я, наверное, что-то упускаю в трассировке стека ... кто-нибудь видит подходящую строку?

Tasks: TOP => assets:precompile

Answer 1

rake assets:precompile инициализирует ваше приложение по умолчанию, которое включает в себя подключение к базе данных.

Внутри config/application.rb вы можете добавить это, но см. Ссылку ниже для предупреждений об этом:

config.assets.initialize_on_precompile = false

Руководство по Rails по прекомпиляции ресурсов

Answer 2

Если в вашей ситуации это имеет смысл, вы можете выбрать, в какой среде assets:precompile работать, с помощью следующей команды:

rake assets:precompile:all RAILS_ENV=development RAILS_GROUPS=assets

Это имеет смысл для моего развертывания, потому что обычно:

1. Я делаю рейк, чтобы генерировать активы на моей машине для разработки (потому что память моего vps как-то ограничена)
2. Я архивирую все приложения с активами, сгенерированными в public / assets
3. Я передаю zip в vps и распаковываю туда пакет

Надеюсь, это поможет.

Answer 3

У меня была та же проблема.После обновления Sprockets до версии 3 всякий раз, когда я пытался выполнить предварительную компиляцию ресурсов локально (разработка), но с использованием настроек производственной среды, у меня возникала эта ошибка:

rake aborted! Gem::LoadError: Specified 'postgresql' for database adapter, but the gem is not loaded. Add gem 'pg' to your Gemfile (and ensure its version is at the minimum required by ActiveRecord).

Поскольку в моем локальном (разработка) я использую MySQL, а на сервере (производство) я использую Postgres.

Ответ, помеченный как решенный, не работает для меня, потому что config.assets.initialize_on_precompile недоступно в Rails 4.2.1.

Чтобы решить эту проблему, я выполнил 3 простых шага:

1. Добавьте в свой Gemfile: gem "activerecord-nulldb-adapter"

2. In database.yml, измените адаптер следующим образом:

   production:

   adapter: <%= ENV['DB_ADAPTER'] ||= 'postgresql' %>
   

3. Для локальной компиляции производственных активов.запустите в своем терминале: DB_ADAPTER=nulldb RAILS_ENV=production rake assets:precompile

Это решение решено для меня, и я выпил здесь .

Answer 4

Проверьте ваши файлы конфигурации (во всех средах).Если, например,

rake assets:precompile

работает в процессе разработки, но у вас возникают проблемы в работе

RAILS_ENV=production bundle exec rake assets:precompile

, то, скорее всего, у вас есть ссылка на активную запись в вашей / config /environment / production.rb

config.active_record.dump_schema_after_migration = false

Во избежание всего этого, если вы планируете не использовать преимущества активной записи или использовать NoSQL, такой какМонго, вы можете инициализировать ваше новое приложение следующим образом:

rails new myApp --skip-active-record

, что для меня эквивалентно -O (заглавная O).
