# `MishkaCmsMigration.Resources.Changes.Choices`
[🔗](https://github.com/mishka-group/mishka_cms_migration/blob/v0.0.1/lib/mishka_cms_migration/resources/__changes/choices.ex#L5)

Folds what the New import window's steps ask apart from the run's Advanced options into the run's
`options`: the `bring` argument (the switches of what to bring, such as `"bring_posts"` and
`"comments"`) and the `language` argument (the one language to put every item of an unknown or
unpublished language in, blank to keep the source's languages), as the run's `"one_language"`.

    create :create do
      argument :bring, :map
      argument :language, :string
      change MishkaCmsMigration.Resources.Changes.Choices
    end

It runs before the options are checked (`MishkaCmsMigration.MigrationRun.Options`), so a switch
typed as `"false"` becomes a boolean and every key left alone keeps its default there. A language
that is not one of the site's is refused in words, under the language field.
