What if you wanted different databases to each environment so you can test your application?

kinda like rails do.

Hey, Júnior, I hope you are very well. I didn't know you can do that with Rails. I'm very new in this ecosystem and in Ruby in general. But I don't know how to add different databases to each environment. Maybe you can find the answer asking here: [github.com/hanami/hanami/issues.](https://github.com/hanami/hanami/issues.) Or in its discourse site: [discourse.hanamirb.org](https://discourse.hanamirb.org/) Or in its subreddit: [reddit.com/r/hanamirb](https://www.reddit.com/r/hanamirb/)

Sorry, I can help you with your question. Thank you for your question.

Have a nice day.
