如何从外部配置 Sinatra 应用程序？

Question

这是我的代码：

require 'sinatra/base'
class Front < Sinatra::Base
  get '/' do
    settings.foo
  end
end

我运行是这样的：

app = Front.new
app.set(:foo, 'Hello, world!') // doesn't work!
app.run!

我想以某种方式将 foo 注入应用程序并在运行之前预配置 other params。我得到：

undefined method `set' for #<Sinatra::Wrapper:0x007fea3729a990>
Did you mean?  send (NoMethodError)

怎么了？

您必须在初始化之前通过选项。以下应该有效：

Front.set :foo, 'Hello, world!'
app = Front.run!
