The pgreset gem makes it possible to run rails db:reset against a postgres database with active connections. It should eliminate "database in use" errors from rails.
Credit for the original solution goes to Manuel Meurer.
Add this line to your application's Gemfile:
gem 'pgreset'And then execute:
$ bundle
Or install it yourself as:
$ gem install pgreset
Now you can run rails db:reset as normal, and rails will kill active connections to the database being reset:
$ rails db:reset
After checking out the repo, run bin/setup to install dependencies. You can also run bin/console for an interactive prompt that will allow you to experiment.
To install this gem onto your local machine, run bundle exec rake install. To release a new version, update the version number in version.rb, and then run bundle exec rake release, which will create a git tag for the version, push git commits and tags, and push the .gem file to rubygems.org.
