EventsHookAnnotationName is the value of the annotation when read during ent compilation

Functions

func GraphKeyDirective

func GraphKeyDirective(fields string) entgql.Annotation

GraphKeyDirective returns an entgql.Directive for setting the @key field on a graphql type

func MarshalRawMessage

func MarshalRawMessage(t json.RawMessage) graphql.Marshaler

MarshalRawMessage provides a graphql.Marshaler for json.RawMessage

func UnmarshalRawMessage

func UnmarshalRawMessage(v interface{}) (json.RawMessage, error)

UnmarshalRawMessage provides a graphql.Unmarshaler for json.RawMessage

Types

type EventsHookAnnotation

type EventsHookAnnotation struct {
	SubjectName               string
	AdditionalSubjectRelation string
}

EventsHookAnnotation provides a ent.Annotation spec. These shouldn't be set directly, you should use EventsHookAdditionalSubject() and EventsHookSubjectName instead

func EventsHookAdditionalSubject

func EventsHookAdditionalSubject(relation string) *EventsHookAnnotation

EventsHookAdditionalSubject marks this field as a field to return as an additional subject

func EventsHookSubjectName

func EventsHookSubjectName(s string) *EventsHookAnnotation

EventsHookSubjectName sets the subject name that is where the messages for this object will be sent

func (EventsHookAnnotation) Name

func (a EventsHookAnnotation) Name() string

Name implements the ent Annotation interface.

type Extension

type Extension struct {
	entc.DefaultExtension
	// contains filtered or unexported fields
}

Extension is an implementation of entc.Extension that adds all the templates that entx needs.

func NewExtension

func NewExtension(opts ...ExtensionOption) (*Extension, error)

NewExtension returns an entc Extension that allows the entx package to generate the schema changes and templates needed to function

func (*Extension) GQLSchemaHooks

func (e *Extension) GQLSchemaHooks() []entgql.SchemaHook

GQLSchemaHooks of the extension to seamlessly edit the final gql interface.

func (*Extension) Templates

func (e *Extension) Templates() []*gen.Template

Templates of the extension

type ExtensionOption

type ExtensionOption func(*Extension) error

ExtensionOption allow for control over the behavior of the generator

func WithEventHooks

func WithEventHooks() ExtensionOption

WithEventHooks adds the templates for generating event hooks

func WithFederation

func WithFederation() ExtensionOption

WithFederation adds support for graphql federation by adding the Entity interface to all types, as well as removing the node() and nodes() query calls.

func WithJSONScalar

func WithJSONScalar() ExtensionOption

WithJSONScalar adds the JSON scalar definition

type TimestampsMixin

type TimestampsMixin interface {
	ent.Mixin
	CreatedAtAnnotations(...schema.Annotation) TimestampsMixin
	UpdatedAtAnnotations(...schema.Annotation) TimestampsMixin
}

TimestampsMixin defines an interface of a Mixin that provides the created_at and updated_at timestamp fields

func NewTimestampMixin

func NewTimestampMixin() TimestampsMixin

NewTimestampMixin returns a Mixin that provides the created_at and updated_at timestamp fields
