Module: ElasticGraph::Apollo::SchemaDefinition::EntityTypeExtension

Defined in:: lib/elastic_graph/apollo/schema_definition/entity_type_extension.rb

Overview

The Apollo ‘_Entity` type is a union of all entity types in an ElasticGraph schema. These overrides prevent ElasticGraph from treating `_Entity` like a normal indexed union type, which would trigger unwanted derived schema generation and validation.

Instance Method Summary collapse

#directly_queryable? ⇒ Boolean

‘_Entity` is never directly queryable from the root `Query` type.
#graphql_fields_by_name ⇒ Object

A merged set of ‘graphql_fields_by_name` cannot be safely computed.
#root_document_type? ⇒ Boolean

‘_Entity` is never a root document type, and should not be treated as one (even though its subtypes are all root document types, which would usually cause it to be treated as a root document type!).

Instance Method Details

#directly_queryable? ⇒ `Boolean`

‘_Entity` is never directly queryable from the root `Query` type. It’s queried via the apollo ‘_entities(representations: …)` field instead.

Returns:

(Boolean)

def directly_queryable?
  false
end

#graphql_fields_by_name ⇒ `Object`

A merged set of ‘graphql_fields_by_name` cannot be safely computed. That method raises errors if a field with the same name has conflicting definitions on different subtypes, but we must allow that on `_Entity` subtypes.
