haml中的处理流程如何工作? [英] how does processing flow in haml work?

问题描述

我有一个run.haml文件，用于运行测试服.一切正常，但我想在用户单击将他引至该haml的链接后立即显示文本正在启动测试套件:#{params ['run']}".

I have a run.haml file where I run a test suit. Everything works just fine but I want to display the text "Starting test suite: #{params['run']}" immediately after user clicks the link that leads him to this haml.

点击的链接告诉haml需要执行什么诉讼

the link clicked tells haml what suit needs to be executed

%a(href="run?run=#{file}")

现在，测试服运行完成后，所有内容都会显示.将一直加载run.haml页面，直到脚本完成.

Right now everything is displayed after the test suit run finishes. The run.haml page is being loaded till the script finishes.

• halm 处理流程如何工作?
• 页面开始呈现后我可以开始处理作业吗?
• 我可以在浏览器中显示一些文本吗?然后让我们打电话给测试服吗?

• how does the haml processing flow work?
• can I start processing the job after the page starts rendering?
• can I display some text in a browser and then let call the test suit?

完成测试服的运行需要几分钟的时间.

It takes minutes to finish the run of the test suit.

    !!!  
    %html  
      %head  
        %title Running  
      %body
        = "Starting test suite: #{params['run']}"
        - output = %x[cd C:\\Program Files\\TestPro\\TestPro Automation Framework410 && ant -lib lib -f "C:\\Program Files\\TestPro\\TestPro Automation Framework410\\Output Files\\builds\\#{params['run']}.xml"]
        -#The result is
        %br
        = output.split("\n")[-2,2].join("<BR>")
        = "<br/>"*2
        %a(href="/")back to suits list

推荐答案

好吧，看-我的想法是，直到该函数调用返回后，它才呈现所有内容(无论出于何种原因).

Well, look -- my thought here is that it's not rendering everything (for whatever reason) until that function call returns.

在这种情况下，您需要与加载测试工具页面分开处理该函数的结果-因此，您将要使用

If that's the case, you'll want to process the result of that function separately from loading the test harness page -- so, you'll want to invoke the test suite either with

• Ajax调用，或者
• 单独的工作线程

• an Ajax call or,
• a separate worker thread

该选择取决于函数(通常)运行的时间长度-因此，根据复杂程度，对于 run_later 或 delayed_job ，甚至是自定义守护程序.

That choice depends on the length of time the function (generally) takes to run -- so, depending on the complexity, it may be a good candidate for something like BackgrounDRb, run_later or delayed_job, or even a custom daemon.

最后，您可能会发现将Sinatra与delay_job结合使用的示例很有帮助.

Finally, you may find this example of using Sinatra with delayed_job helpful.
