[英]When I try adding rack-flash to my sinatra app it stops working
I've been using Rack::Flash
for a while to display flash notices on responses in my Sinatra apps. 我一直在使用
Rack::Flash
在我的Sinatra应用程序中显示响应的闪光通知。 Since I upgraded to Sinatra 1.3.2, the app crashes, logging the following whenever I make a request to the server: 自从我升级到Sinatra 1.3.2后,应用程序崩溃,每当我向服务器发出请求时都会记录以下内容:
!! Unexpected error while processing request: undefined method `<<' for nil:NilClass
The simplified code looks like this: 简化的代码如下所示:
require 'sinatra'
require 'rack-flash'
enable :sessions
use Rack::Flash
get "/" do
"Hello World"
end
Any idea why this could be happening? 知道为什么会发生这种情况吗?
rack-flash doesn't work with the latest versions of rack. rack-flash无法与最新版本的机架配合使用。 Try sinatra-flash instead.
请尝试使用sinatra-flash 。
