Class Method Details

.resolve(relation, lookahead:, type:, required_associations: [], required_columns: []) ⇒ Object

required_associations:/required_columns: name associations/columns the caller needs loaded regardless of what the client requested (e.g. a model's #discussion reading title/body and persona.handle to find_or_open a thread, even when the query didn't ask for those fields). Passing these through here, rather than chaining .select/.includes onto the return value, is required for correctness: #resolve returns a plain Array (not a Relation — see Resolver#resolve_relation) whenever the query also requests a nested GraphQL-mapped association, and a caller-side .select/.includes chained after the call silently breaks the moment that happens.
