activos de rake: precompilación que intenta conectarse a la base de datos

Question

Estoy intentando depurar por qué mi aplicación está intentando conectarse a mi base de datos cuando ejecuto rake assets:precompile --trace.

Probablemente me falta algo en la pila ... ¿alguien ve la línea correspondiente?

Tasks: TOP => assets:precompile 

Answer 1

rake assets:precompile inicializa su aplicación por defecto, el cual incluye la conexión a la base de datos.

Dentro config/application.rb puede agregar esto, pero consulte el siguiente enlace para las advertencias al respecto:

config.assets.initialize_on_precompile = false 

Rails Guide on Precompiling Assets

Answer 2

Si tiene sentido en su situación, puede elegir contra qué entorno assets:precompile debería funcionar , con el siguiente comando:

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

Esto tiene sentido para mi implementación porque generalmente:

1. hago rastrillo para genera activos en mi máquina de desarrollo (debido a la memoria de mis VPS es de alguna manera limitado)
2. que comprimir todo la aplicación con los activos generados en público/activos
3. puedo transferir el zip a la vps ans descomprimir el paquete allí

Espero que ayude.

Answer 3

Tuve el mismo problema. Después de actualizar los piñones a la versión 3, siempre que trataba precompilar los activos a nivel local (desarrollo), sin embargo el uso de la configuración del entorno de producción, tuve este error:

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

Porque en mi local (desarrollo) Yo uso MySQL y en el servidor (producción), uso Postgres.

La respuesta marcada como resuelta no funciona para mí, porque config.assets.initialize_on_precompile no está disponible en Rails 4.2.1.

de resolver, seguí 3 pasos simples:

1. En su Gemfile, añadir: gem "activerecord-nulldb-adapter"

2. En database.yml, cambie el adaptador de la siguiente manera:

   production:

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

3. Para compilar sus activos de producción loca lly. correr en su terminal: DB_ADAPTER=nulldb RAILS_ENV=production rake assets:precompile

Esta solución resuelve a mí y yo sawyed here.
