问题 Is there a simple way to setup different .gitignore files for different remotes? I have a repository I push up to both Heroku and Github. I need database.yml for Heroku, but don't want some of the information to be pushed up to Github. So I need a different .gitignore file for each of the remotes.

Rails 3 and Heroku: automatically “rake db:migrate” on push?

阅读更多关于 Rails 3 and Heroku: automatically “rake db:migrate” on push?

问题 I have a slight annoyance with my heroku push/deploy process, which otherwise has been a joy to discover and use. If i add a new migration to my app, the only way i can get it up onto the heroku server is to do a push to the heroku remote. This uploads it and restarts the app. But it doesn't run the migration, so i have to do heroku rake db:migrate --app myapp , then heroku restart --app myapp . In the meantime, the app is broken because it hasn't run the migrations and the code is referring

问题 Let me start by saying, that I don't think there is a way to do this... but, there are a lot of clever people out there and so I thought I would ask! :) I found a good article/post by Randall Degges on setting up a Django app on Heroku (Internet Archive link). I really like what he has to say about breaking your requirements up into different files (common.txt, dev.txt, prod.txt etc). This works great on Heroku for production, but I also maintain a Dev/QA site on Heroku, and I have a few
