How to change/set :mnesia folder in elixir?

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.

Solution

  • 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')
