Class Method Details

.use(schema, dynamic: false, profiles: EmptyObjects::EMPTY_HASH, preload: (Rails) ? Rails.env.production? : nil), migration_errors: false) ⇒ Object

Parameters:

  • schema (Class<GraphQL::Schema>)
  • profiles (Hash<Symbol => Hash>) (defaults to: EmptyObjects::EMPTY_HASH) —

    A hash of name => context pairs for preloading visibility profiles

  • preload (Boolean) (defaults to: (Rails) ? Rails.env.production? : nil)) —

    if true, load the default schema profile and all named profiles immediately (defaults to true for Rails.env.production?)

  • migration_errors (Boolean) (defaults to: false) —

    if true, raise an error when Visibility and Warden return different results
