为＆＃39; capistrano-maintenace＆＃39;配置maintenance_template_path。宝石

Question

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

我已经尝试了

# 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。

该文件位于正确的位置/Users/David/Documents/Development/myRailsApp/app/views/errors/maintenance.erb.html

正确的配置是什么？

它需要绝对路径。假设您正在使用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__)
