Instance Method Details

#validate(input = params, required_keys: [], contract: nil) ⇒ Object

Explicit validation helper intended to be called from action methods.

Supports either:

  • required_keys: simple presence checks on Hash-like params (DEPRECATED — use the ‘input` DSL with `required: true` instead)

  • contract: a dry-validation-like contract responding to ‘call(input)` and returning an object that responds to `success?` and `errors`
