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.
Special thanks to Emil Kampp and Michael Yin for adding Rails 6.1 support.
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.
