Overview
A GraphQL schema which may be queried with Query.
The Schema contains:
- types for exposing your application
- query analyzers for assessing incoming queries (including max depth & max complexity restrictions)
- execution strategies for running incoming queries
Schemas start with root types, Schema.query, Schema.mutation and Schema.subscription.
The schema will traverse the tree of fields & types, using those as starting points.
Any undiscoverable types may be provided with the types
configuration.
Schemas can restrict large incoming queries with max_depth
and max_complexity
configurations.
(These configurations can be overridden by specific calls to Schema.execute)
Schemas can specify how queries should be executed against them.
query_execution_strategy
, mutation_execution_strategy
and subscription_execution_strategy
each apply to corresponding root types.

.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.

.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.
