How to change/set :mnesia folder in elixir?

Question

Is there a way to set mnesia folder in Elixir?

There is a way to set this folder using 'mnesia-dir' parameter in command line, but it is not a convenient way.

Answer 1

There are two ways:

1- Add it in your config.exs:

config :mnesia,
   dir: 'mydb_#{Mix.env}'

2- Use environments:

Application.put_env(:mnesia, :dir, '/tmp/wowdb')
