A friend of mine @markbadolato got me into using this git post-checkout hook:
https://gist.github.com/mbadolato/5869968
update: he also made a blog post with more explanations.
#!/bin/bash
# Put this file at: .git/hooks/post-checkout
# and make it executable
# You can install it system wide too, see http://stackoverflow.com/a/2293578/685587
PREV_COMMIT=$1
POST_COMMIT=$2
NOCOLOR='\x1B[0m'
REDCOLOR='\x1B[37;41m'
if [[ -f composer.lock ]]; then
DIFF=`git diff --shortstat $PREV_COMMIT..$POST_COMMIT composer.lock`
if [[ $DIFF != "" ]]; then
echo -e "$REDCOLOR composer.lock has changed. You must run composer install$NOCOLOR"
fi
fi
if [[ -f app/console ]]; then
php app/console doctrine:schema:update --dump-sql
fi |
Mind you need to do it as a post-checkout hook.
I added the doctrine part so that it also tells you if you need to run migrations or update the schema.
All credits to its author. I only added the last part. And I adapted it from @markbadolato polished version.
