#merge(passed) ⇒ Object

Merge an auto-generated config (‘passed`) into this user-maintained one so that `MongoidSchemaGenerator` regenerations preserve hand-edited values.

  • structural facts come from the freshly generated config: primary_key, belongs_tos, embedded_in.

  • user customizations are kept from the receiver: filter, ignore, bulk_insert_chunk_size, and each field’s ‘replace_with` masking rule.

  • generated fields drive the field list (so added/removed fields track the model), but a matching receiver field wins to retain its masking.

#reject_ignored_members! ⇒ Object

Drop the belongs_tos/fields flagged ‘ignore:true` so they are excluded from extraction. The config files on disk keep these entries; this is applied to the runtime config right after it is loaded (see Runner#load_table_config).
