Overview

Extend this class to define GraphQL enums in your schema.

By default, GraphQL enum values are translated into Ruby strings. You can provide a custom value with the value: keyword.

Examples:

# equivalent to
# enum PizzaTopping {
#   MUSHROOMS
#   ONIONS
#   PEPPERS
# }
class PizzaTopping < GraphQL::Enum
  value :MUSHROOMS
  value :ONIONS
  value :PEPPERS
end

.unauthorized_field(unauthorized_error) ⇒ Field

This hook is called when a field fails an authorized? check.

By default, this hook implements the same behavior as unauthorized_object.

Whatever value is returned from this method will be used instead of the unauthorized field . If an error is raised, then nil will be used.

If you want to add an error to the "errors" key, raise a ExecutionError in this hook.

Parameters:

Returns:

  • (Field) —

    The returned field will be put in the GraphQL response

.unauthorized_object(unauthorized_error) ⇒ Object

This hook is called when an object fails an authorized? check. You might report to your bug tracker here, so you can correct the field resolvers not to return unauthorized objects.

By default, this hook just replaces the unauthorized object with nil.

Whatever value is returned from this method will be used instead of the unauthorized object (accessible as unauthorized_error.object). If an error is raised, then nil will be used.

If you want to add an error to the "errors" key, raise a ExecutionError in this hook.

Parameters:

Returns:

  • (Object) —

    The returned object will be put in the GraphQL response

#type_error(err, ctx) ⇒ Object

When we encounter a type error during query execution, we call this hook.

You can use this hook to write a log entry, add a ExecutionError to the response (with ctx.add_error) or raise an exception and halt query execution.

Examples:

A nil is encountered by a non-null field

type_error ->(err, query_ctx) {
  err.is_a?(GraphQL::InvalidNullError) # => true
}

An object doesn’t resolve to one of a UnionType’s members

type_error ->(err, query_ctx) {
  err.is_a?(GraphQL::UnresolvedTypeError) # => true
}

Parameters:

  • err (GraphQL::TypeError) —

    The error encountered during execution

  • ctx (GraphQL::Query::Context) —

    The context for the field where the error occurred

Returns:

  • void

See Also:

  • is the default behavior.
