为 'capistrano-maintenace' 配置 maintenance_template_path gem

Question

在 capistrano/maintenance gem 中，我无法设置 :maintenance_template_path 变量的路径。

我试过了

# Set the maintenance file path
set :maintenance_template_path, '/views/errors/maintenance'
set :maintenance_template_path, '/errors/maintenance'
set :maintenance_template_path, '/app/views/errors/maintenance'
set :maintenance_template_path, '/errors/maintenance.erb.html'
set :maintenance_template_path, '/views/errors/maintenance.erb.html'
set :maintenance_template_path, 'app/views/errors/maintenance.erb.html'

我一直收到 No such file or directory @ rb_sysopen 错误。

文件在正确的位置/Users/David/Documents/Development/myRailsApp/app/views/errors/maintenance.erb.html

正确的配置是什么？

需要绝对路径。假设您使用的是 config/deploy.rb，那么您可以这样做：

set :maintenance_template_path, 
    File.expand_path("../../app/views/errors/maintenance.erb.html", __FILE__)
