# `MishkaCmsMigration.Resources.Validations.Connectable`
[🔗](https://github.com/mishka-group/mishka_cms_migration/blob/v0.0.1/lib/mishka_cms_migration/resources/__validations/connectable.ex#L5)

Holds a step that queues a job, Run again (`:start_dry_run`) and the jobs of picked items
(`:dry_run_items`, `:import_items`), on a run that still holds what its source connects with
(`MishkaCmsMigration.MigrationRun.connectable?/1`): its sealed password, or the file it was
handed. A run an earlier release ended cleared both, and its job could only fail on the source's
refusal, so it is refused before anything is queued, in words: "This run no longer holds its
WordPress password. Start a New import.", or its file, for a source that reads one.

    update :start_dry_run do
      validate MishkaCmsMigration.Resources.Validations.Connectable
    end

It reads the run as the action was handed it, with no query, also when the action runs
atomically: a run's secret and file are cleared only by `:cancel`, which leaves it in a status
`MishkaCmsMigration.Resources.Validations.Status` refuses.
