heroku

问题 I am new to Heroku platform. My requirement is to run a python command line tool from Heroku. I am not sure if this can be done directly as applications over there are the web applications with other mandatory files such as procfile etc. The approach I am thinking to take is to create a web app that could call the python script. But next question comes up is how to call python script which allows passing arguments to it too. And do I need to deploy the python tool and web app separately?

问题 We've got a Rails app where certain requests trigger long-running tasks on a worker dyno with delayed_job, while the front-end polls until it receives a result. Our traffic is small but growing, and the tasks generally take only a few seconds to complete, but can take up to a minute. Right now a single web and worker dyno each should be sufficient to handle our load. The problem is, the delayed_job queue won't process jobs in parallel, so a longer task ends up holding up the tasks behind it.

问题 I am running Rails 3.2.8 and built an app which links to a custom CSS file and images. The custom CSS file is placed in my Assets/stylesheets folder and images are in Assets/images. For some reason, the CSS and images don't load when I push the app to Heroku. The app generates a manifest.yml file which contains all the images and CSS file. The CSS file is a customised version of Twitter Bootstrap: http://twitter.github.com/bootstrap/index.html Hope you guys can help and thanks in advance! 回答1
