Capistrano部署后未编译Rails资产 [英] Rails assets aren't compiling after Capistrano deployment

问题描述

我正在使用Capistrano部署我的Rails应用程序，除非我将ssh放入服务器并手动运行RAILS_ENV=development bundle exec rake assets:precompile，否则似乎不会对资产进行编译.

I'm deploying my Rails app using Capistrano and it seems that the assets aren't being compiled unless I ssh into the server and run RAILS_ENV=development bundle exec rake assets:precompile manually.

我已经尝试按照 capistrano/rails github页面上的说明进行操作，但我不是确定我是否错过了什么.

I've tried following the instructions on the capistrano/rails github page, but I'm not sure if I've missed something.

运行cap production deploy成功完成.但是我不知道如何检查assets:precompile任务是否真正运行.运行cap production deploy:assets:precompile也可以成功完成，但是服务器上没有明显变化.

Running cap production deploy completes successfully. But I don't know how to check whether the assets:precompile task was actually run. Running cap production deploy:assets:precompile also completes successfully, but with no apparent change on the server.

Capfile

require 'capistrano/setup'
require 'capistrano/deploy'

require 'capistrano/rbenv'
require 'capistrano/rails/assets'

Dir.glob('lib/capistrano/tasks/*.cap').each { |r| import r }

config/deploy.rb

set :application, "website"
set :repo_url, "[e-mail]:company/website.git"
set :deploy_to, "/var/www/#{fetch(:application)}"
set :user, "webmaster"

set :rbenv_path, '/home/webmaster/.rbenv'
set :rbenv_ruby, '2.2.3'

set :assets_roles, [:web, :app]
set :keep_assets, 2

set :linked_dirs, fetch(:linked_dirs, []).push('log', 'tmp/pids', 'tmp/cache', 'tmp/sockets', 'vendor/bundle', 'public/system', 'public/uploads')
set :linked_files, fetch(:linked_files, []).push('config/database.yml', 'config/secrets.yml')

config/deploy/production.rb

set :stage, :production

server 'company.com', user: 'webmaster', roles: %{web app db}

为什么不编译资产?

  gem 'capistrano-rails', '~> 1.1.1'
  gem 'capistrano-rbenv', '~> 2.0.4'
end

Capfile

require 'capistrano/setup'
require 'capistrano/deploy'
require 'capistrano/rbenv'
require 'capistrano/rails' # Same as requiring capistrano/bundler, capistrano/rails/assets and capistrano/rails/migrations

Dir.glob('lib/capistrano/tasks/*.cap').each { |r| import r }

config/deploy.rb

set :application, "website"

set :repo_url, "[e-mail]:company/website.git"
set :deploy_to, "/var/www2/#{fetch(:application)}"

set :user, "webmaster"

set :rbenv_path, '/home/webmaster/.rbenv'

namespace :deploy do

      execute :touch, release_path.join("tmp/restart.txt")

  after "deploy:publishing", "deploy:restart"

end

config/deploy/production.rb

确保使用％w {}

set :stage, :production

server 'company.com', user: 'webmaster', roles: %w{web app db}

部署的输出

如果成功，您应该在输出中看到与此类似的内容:

If successful, you should see something similar to this in your output:

INFO [2412d16d] Running /home/webmaster/.rbenv/bin/rbenv exec bundle exec rake assets:precompile as [e-mail]
DEBUG [2412d16d] Command: cd /var/www/website/releases/20160302030846 && ( export RBENV_ROOT="/home/webmaster/.rbenv" RBENV_VERSION="2.2.3" RAILS_ENV="production" ; /home/webmaster/.rbenv/bin/rbenv exec bundle exec rake assets:precompile )

推荐答案

由于拼写错误，您没有为服务器正确分配角色:

You've not assigned roles to your servers properly, due to a very subtle typo:

server 'company.com', user: 'webmaster', roles: %{web app db}

应该是:

server 'company.com', user: 'webmaster', roles: %w{web app db}

在Ruby中，%{}与双引号字符串相同，而%w{}是字符串数组.您需要后者，以便服务器具有三个角色web，app和db，而不是一个名为web app db的角色.

In Ruby, %{} is the same as a double-quoted string, whereas %w{} is an array of strings. You want the latter, so that your server has the three roles, web, app, and db, not one role named web app db.
