Rails 4 - Производственные активы: предварительная компиляция приводит к ActiveRecord::NoDatabaseError: FATAL: база данных не существует

Не могу понять, почему я больше не могу прекомпилировать ресурсы перед отправкой в ​​Heroku. Подробности ниже. В настоящее время работает Rails 4.1.6. Некоторая другая, возможно, актуальная информация:

Версия бандлера 1.7.12.
gem 'activeadmin', github: 'activeadmin'
gem 'formtastic', '3.1.2'

Все, что я могу найти, это ссылки на pre-Rails 4, когда config.assets.initialize_on_precompile = false это исправит, что больше не применяется.

Любые идеи, почему он пытается подключиться к базе данных?

> RAILS_ENV=production bundle exec rake assets:precompile

rake aborted!

Похоже, у вас есть ссылка на app/admin/product.rb где-то в ваших ресурсах, но база данных еще не создана. Вы уже запустили rake db:create db:migrate в рабочей среде?   -  person zwippie    schedule 20.01.2015

Ранее я выполнял развертывание на Heroku, так что да, у меня есть производственная база данных. Но я делаю эту предварительную компиляцию локально, так что это не должно применяться?   -  person uhezay    schedule 20.01.2015

Я не верю, что я целенаправленно ссылался на этот файл в активах, мысли о том, как его отследить? Этот файл не новый (просто значительно изменился) с тех пор, как я в последний раз пытался его развернуть (и прекомпиляция работала).   -  person uhezay    schedule 20.01.2015

Если вы компилируете ресурсы для производства на своем компьютере для разработки, и в этом процессе он обращается к базе данных, он ожидает, что база данных будет доступна, как настроено в production. Существует ли эта производственная БД на вашей машине разработки? Если да, заполнен ли он необходимыми начальными данными?   -  person zwippie    schedule 20.01.2015

Похоже, я был слишком сосредоточен на последних строках ошибки и пробовал все, что я читал на страницах, ссылающихся на похожий текст (наряду с разными результатами между несколькими средами Heroku, которые меня больше сбивали с толку), и пропустил соответствующие строки product.rb, которые могли бы указали мне на проблему. У меня есть ссылки на базу данных при настройке областей и фильтров для этой конкретной страницы, я не осознавал, что это повлияет на создание активов.

Product.pluck(:type).uniq.sort.each do |p|
  scope(p) { |scope| scope.where(type: p) }
end

filter :type, as: :select, collection: Product.pluck(:type).uniq.sort

После комментирования этих строк предварительная компиляция снова работает нормально.

Как только я понял, что искать, нашел это: https://github.com/activeadmin/activeadmin/issues/2781

Поэтому лучшим решением было добавить это в route.rb:

ActiveAdmin.routes(self) unless ARGV.grep(/assets:(precompile|clean)/).any?
