从实例方法中获取sinatra环境

Question

确定环境的正确方法是什么？现在我正在使用:

class Main < Sinatra::Base
    get '/' do
        puts self.class.development?
        puts self.class.production?
    end
end

但这似乎不对.

Answer 1

我会使用Sinatra::Base.development?或者Sinatra::Base.production?因为那是方法的来源.

Answer 2

self.class.development?应该真的有效.这些都适用于Sinatra 1.3.1:

class Main < Sinatra::Base
  get '/' do
    puts Main.development?
    puts self.class.development?
    puts settings.development?
    puts settings.environment == :development
  end
end
