执行脚本并在视图中显示输出/进度 [Ruby/Sinatra(Rails)]
我有一个部署脚本，是从我的 Sinatra 应用程序中的助手调用的。
我想显示一个“部署”视图/页面，然后执行脚本。
然后，当脚本完成时，显示一个带有文本框的新页面，其中包含脚本输出。
这是如何完成的？
# update.rb - the main app
helpers do
def run_update
command = "./script.sh"
@ok = system( command )
end
end
post '/version' do
run_update # putting this after the erb call doesnt fix it!?
erb :version
end
目前，它在主页发布帖子后挂起。然后，当脚本完成时，它会显示 version.erb 文件。
I have a deploy script that is called from a helper in my Sinatra app.
I want show a "deploying" view/page, then exec the script.
Then when the script is finished, show a new page with text box with the script output in.
How can this be done?
# update.rb - the main app
helpers do
def run_update
command = "./script.sh"
@ok = system( command )
end
end
post '/version' do
run_update # putting this after the erb call doesnt fix it!?
erb :version
end
Currently it hangs after the post is made from the main page. Then when the script is finished it displays the version.erb file.

我想我正在寻找的是 IO#popen

您可以将输出重定向到文件并通过 HTTP 显示该文件并保持每 x 秒刷新页面
You can redirect the output to a file and display the file over HTTP and keep refreshing the page every x seconds
