Module: Yes::Core::Commands::GroupPayloadNormalizer

Defined in:
lib/yes/core/commands/group_payload_normalizer.rb

Overview

Normalizes a flat or partially-nested input hash into the per-context / per-subject shape expected by a command group’s sub-commands.

Supports three input forms simultaneously:

* keys that match a command context are passed through verbatim,
* keys that match a subject of the own context are nested one level
  under the own context,
* any other key is nested two levels under
  <own_context>.<own_subject>.

This is the shared payload-shaping primitive for Group (legacy stateless flow) and CommandGroup (aggregate-DSL flow).

Class Method Details

.call(params, command_contexts:, own_context_subjects:, own_context:, own_subject:) ⇒ Hash

Returns the normalized payload (reserved keys stripped).

Parameters:

  • params (Hash) —

    the raw input hash, including reserved keys

  • command_contexts (Array<Symbol>) —

    unique contexts of all commands in the group

  • own_context_subjects (Array<Symbol>) —

    subjects in the group’s own context

  • own_context (Symbol) —

    the group’s own context

  • own_subject (Symbol) —

    the group’s own subject

Returns:

  • (Hash) —

    the normalized payload (reserved keys stripped)
