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)

Examples:

defining a schema

class MySchema < GraphQL::Schema
  query QueryType
  # If types are only connected by way of interfaces, they must be added here
  orphan_types ImageType, AudioType
end

end

Parameters:

  • application_object (Object) —

    Some object encountered by GraphQL-Ruby while running a query

  • graphql_type (Class, Module) —

    The type that GraphQL-Ruby is using for application_object during this query

  • context (GraphQL::Query::Context) —

]
results = MySchema.multiplex(queries)
render json: {
  result_1: results[0],
  result_2: results[1],
}

Parameters:

  • queries (Array<Hash>) —

    Keyword arguments for each query

  • context (Hash) —

    Multiplex-level context

Returns:

.object_from_id(object_id, context) ⇒ Object?

Fetch an object based on an incoming ID and the current context. This method should return an object from your application, or return nil if there is no object or the object shouldn’t be available to this operation.

Examples:

Fetching an object with Rails’s GlobalID

def self.object_from_id(object_id, _context)
  GlobalID.find(global_id)
  # TODO: use `context[:current_user]` to determine if this object is authorized.
end

Parameters:

  • object_id (String) —

    The ID to fetch an object for. This may be client-provided (as in node(id: ...) or loads:) or previously stored by the schema (eg, by the ObjectCache)

  • context (GraphQL::Query::Context) —

    The context for the currently-executing operation

Returns:

  • (Object, nil) —

    The application which object_id references, or nil if there is no object or the current operation shouldn’t have access to the object

Raises:

end

.orphan_types(*new_orphan_types) ⇒ Array<Class<GraphQL::Schema::Object>>

Tell the schema about these types so that they can be registered as implementations of interfaces in the schema.

This method must be used when an object type is connected to the schema as an interface implementor but not as a return type of a field. In that case, if the object type isn’t registered here, GraphQL-Ruby won’t be able to find it.

Parameters:

  • new_orphan_types (Array<Class<GraphQL::Schema::Object>>) —

    Object types to register as implementations of interfaces in the schema.

Returns:

.rescue_from(*err_classes, &handler_block) {|error, object, arguments, context| ... } ⇒ Object

Register a handler for errors raised during execution. The handlers can return a new value or raise a new error.

Examples:

Handling “not found” with a client-facing error

rescue_from(ActiveRecord::NotFound) { raise GraphQL::ExecutionError, "An object could not be found" }

Parameters:

  • err_classes (Array<StandardError>) —

    Classes which should be rescued by handler_block

  • handler_block —

    The code to run when one of those errors is raised during execution

Yield Parameters:

  • error (StandardError) —

    An instance of one of the configured err_classes

  • object (Object) —

    The current application object in the query when the error was raised

  • arguments (GraphQL::Query::Arguments) —

    The current field arguments when the error was raised

  • context (GraphQL::Query::Context) —

    The context for the currently-running operation

Yield Returns:

  • (Object) —

    Some object to use in the place where this error was raised

Raises:

  • (GraphQL::ExecutionError) —

    In the handler, raise to add a client-facing error to the response

  • (StandardError) —

    In the handler, raise to crash the query with a developer-facing error

end

.resolve_type(abstract_type, application_object, context) ⇒ Class<GraphQL::Schema::Object] The Object type definition to use for `obj`

GraphQL-Ruby calls this method during execution when it needs the application to determine the type to use for an object.

Usually, this object was returned from a field whose return type is an Interface or a Union. But this method is called in other cases, too – for example, when GraphQL::Schema::Argument.loads cases an object to be directly loaded from the database.

Examples:

Returning a GraphQL type based on the object’s class name

class MySchema < GraphQL::Schema
  def resolve_type(_abs_type, object, _context)
    graphql_type_name = "Types::#{object.class.name}Type"
    graphql_type_name.constantize # If this raises a NameError, then come implement special cases in this method
  end
end

Parameters:

  • abstract_type (Class, Module, nil) —

    The Interface or Union type which is being resolved, if there is one

  • application_object (Object) —

    The object returned from a field whose type must be determined

  • context (GraphQL::Query::Context) —

    The query context for the currently-executing query

Returns:

Raises:

Get or set the root subscription { ... } object for this schema.

Examples:

Using Types::Subscription as the entry-point

subscription { Types::Subscription }

Parameters:

  • new_subscription_object (Class<GraphQL::Schema::Object>) (defaults to: nil) —

    The root type to use for subscriptions

.trace_mode(mode_name, trace_class) ⇒ Object

Configure trace_class to be used whenever context: { trace_mode: mode_name } is requested. default_trace_mode is used when no trace_mode: ... is requested.

When a trace_class is added this way, it will not receive other modules added with trace_with(...) unless trace_mode is explicitly given. (This class will not receive any default trace modules.)

Subclasses of the schema will use trace_class as a base class for this mode and those subclass also will not receive default tracing modules.

Parameters:

  • mode_name (Symbol)
  • trace_class (Class) —

    subclass of GraphQL::Tracing::Trace

Returns:

.type_error(type_error, ctx) ⇒ void

This method returns an undefined value.

Called at runtime when GraphQL-Ruby encounters a mismatch between the application behavior and the GraphQL type system.

The default implementation of this method is to follow the GraphQL specification, but you can override this to report errors to your bug tracker or customize error handling.

Parameters:

  • type_error (GraphQL::Error) —

    several specific error classes are passed here, see the default implementation for details

  • context (GraphQL::Query::Context) —

    the context for the currently-running operation

Raises:

.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:
