Capistrano返回错误的release_path

Question

我有一个关于capistrano版本3.2.1的问题.在我的deploy.rb文件中,我使用以下行:

set :theme_path, "#{release_path}/web/app/themes/myproject"

变量release_path没有显示到最新的release文件夹,比如应该说201409151420,但它指向文件夹current,所以输出是:

DEBUG[68031037] Command: cd /var/www/myproject/current/web/app/themes/myproject && ( WP_ENV=staging /usr/bin/env npm install --silent )

输出应该是:

DEBUG[68031037] Command: cd /var/www/myproject/201409151420/web/app/themes/myproject && ( WP_ENV=staging /usr/bin/env npm install --silent )

有谁知道,为什么release_path变量没有显示到正确的文件夹？

谢谢您的帮助.

Answer 1

我认为如果你theme_path懒惰地评估它应该有用:

set(:theme_path) { "#{release_path}/web/app/themes/myproject" }

set :theme_path, lambda { "#{release_path}/web/app/themes/myproject" }

如果release_path未定义,则会看到您看到的值(请参阅dsl/paths.rb):

def release_path
  fetch(:release_path, current_path)
end

也就是说,默认值release_path是current_path.
