运行 Cron 作业时缺少模板

Question

当我们运行 cron 作业时，我们在 Rails 应用程序中遇到了一个奇怪的问题。我们的 cron 作业运行成功，但之后会导致“缺少模板”错误。除非我们解决这个问题，否则测试团队不会允许通过，所以请帮助！

提供代码sn-p和flow。

/etc/crontab

 55 5    * * *   user  sh /root_path/config/cron/shell_commands/environment/test.sh

test.sh

wget http://localhost:3000/cron_jobs/execute_cron_tasks/test/key

cron_jobs/execute_cron_tasks.rb

class CronJobs::ExecuteCronTasksController < ApplicationController
   def test
     CronTasks.test_cron if params[:key] && params[:key] == "key"
     respond_to do |format|
       format.html {render :status => Rack::Utils.status_code(:ok)}
       format.js {render :status => Rack::Utils.status_code(:ok)}
     end
   end
end

模块 cron_tasks.rb

module CronTasks
  def self.test_cron
    puts "=======================working===========================".red
  end
end

调用 cron 作业后，它会打印数据但抛出 500 Internal Server Error

谢谢 问候

我假设您不想在正文中渲染任何内容。在这种情况下，请尝试

format.html {render :status => Rack::Utils.status_code(:ok), :nothing => true}

如果你确实想渲染一个视图，你可能应该把它放进去：

app/views/cron_jobs/execute_cron_tasks/test.html.erb
