I saw Scott Bellware recently write on twitter: for christmas, i really want a git hook to detect if an update has changes in the db/migrations folder
I think Cory and I were quickly searching for which git hook could be used for this idea. Cory found it first and it was the post-merge/post-rebase hooks. I researched the post-merge hook (scroll down to post-merge) and noticed it has no params that we could work with to find out if the last commit had migrations (aka changes/additions to db/migrations folder in a rails project)
I came up with the following :
This will grab the previous diff and look for “db/migrations” in the text. If it’s present, it would auto-run “rake db:migrate && rake db:test:migrate”. In other words, it will migrate the development database schema, then the test database schema.
