If you need to connect to multiple databases in your buffalo app open up your models/models.go file:

Up at the top add a new var like:

1var YourDB *pop.Connection

then in the init() func you can connect to it - the important part is to make sure you call .Open:

1	YourDB, err = pop.NewConnection(&pop.ConnectionDetails{
2		Dialect: "postgres",
3		URL:     envy.Get("EXTRA_DB_URL", "default_url_here"),
4	})
5	if err != nil {
6		log.Fatal(err)
7	}

That’s it! You can now connect to a 2nd database from within your app.
