Class Method Details

.for(model_name, loader) ⇒ Metadata::PermissionDefinition?

Resolves a PermissionDefinition for the given model name.

In :yaml mode, delegates directly to the loader’s YAML-based lookup.

In :model mode, uses first-found-wins resolution (no merging):

1. DB record for this specific model
2. DB record for "_default"
3. YAML fallback for this specific model

Parameters:

  • model_name (String) —

    the model name

  • loader (Metadata::Loader) —

    the metadata loader

Returns:
