atuty rake: prekompilacja próbująca połączyć się z bazą danych

Question

Próbuję debugować, dlaczego moja aplikacja próbuje połączyć się z moją bazą danych po uruchomieniu rake assets:precompile --trace.

Prawdopodobnie brakuje mi czegoś w śladzie stosu ... ktokolwiek widzi stosowną linię?

Tasks: TOP => assets:precompile 

Answer 1

rake assets:precompile inicjuje aplikację domyślnie który obejmuje połączenie z bazą danych.

Wewnątrz config/application.rb można dodać, ale patrz poniższy odnośnik do ostrzeżeń o tym:

config.assets.initialize_on_precompile = false 

Rails Guide on Precompiling Assets

Answer 2

Jeśli to ma sens w sytuacji, można wybrać, przeciwko któremu środowisko assets:precompile powinno działać , z następującym poleceniem:

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

To ma sens w przypadku mojego wdrożenia, ponieważ zazwyczaj:

1. robię grabie do generuje aktywa na moim komputerze rozwoju (bo pamięć o moim VPS jest w jakiś sposób ograniczona)
2. I zip całą aplikację z aktywów generowanych w public/aktywa
3. przenieść zip do vps i rozpakuj pakiet tam

Mam nadzieję, że to pomaga.

Answer 3

Miałem ten sam problem. Po aktualizacji kołem zębatym do wersji 3, ilekroć próbował precompile aktywów lokalnie (rozwój), jednak za pomocą ustawień w środowisku produkcyjnym, miałem ten błąd:

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).

bo moim local (development) Używam MySQL a na serwerze (produkcja) używam PostgreSQL.

Odpowiedź oznaczona jako rozstrzygnięta nie działa dla mnie, ponieważ config.assets.initialize_on_precompile nie jest dostępna w Rails 4.2.1.

Aby rozwiązać, ja po 3 proste kroki:

1. w twojej Gemfile dodać: gem "activerecord-nulldb-adapter"

2. W database.yml zmień zasilacz następująco:

   production:

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

3. Aby skompilować lokację zasobów produkcyjnych Lly. uruchomić w terminalu: DB_ADAPTER=nulldb RAILS_ENV=production rake assets:precompile

to rozwiązało mi rozwiązań i sawyed here.
