Functions ¶
func Bytes ¶
func Bytes(name string) *bytesBuilder
Bytes returns a new Field with type bytes/buffer. In MySQL and SQLite, it is the "BLOB" type, and it does not support for Gremlin.
func Enum ¶
func Enum(name string) *enumBuilder
Enum returns a new Field with type enum. An example for defining enum is as follows:
field.Enum("state").
Values(
"on",
"off",
).
Default("on")
func Float32 ¶
func Float32(name string) *float32Builder
Float32 returns a new Field with type float32.
func Floats ¶
func Floats(name string) *jsonBuilder
Floats returns a new JSON Field with type []float.
func JSON ¶
func JSON(name string, typ interface{}) *jsonBuilder
JSON returns a new Field with type json that is serialized to the given object. For example:
field.JSON("dirs", []http.Dir{}).
Optional()
field.JSON("info", &Info{}).
Optional()
func Strings ¶
func Strings(name string) *jsonBuilder
Strings returns a new JSON Field with type []string.
func Text ¶
func Text(name string) *stringBuilder
Text returns a new string field without limitation on the size. In MySQL, it is the "longtext" type, but in SQLite and Gremlin it has not effect.
Types ¶
type Annotation ¶
type Annotation interface {
// Name defines the name of the annotation to be retrieved by the codegen.
Name() string
}
Annotation is used to attach arbitrary metadata to the field object in codegen. The object must be serializable to JSON raw value (e.g. struct, map or slice). Template extensions can retrieve this metadata and use it inside their templates.
type Descriptor ¶
type Descriptor struct {
Tag string // struct tag.
Size int // varchar size.
Name string // field name.
Info *TypeInfo // field type info.
Unique bool // unique index of field.
Nillable bool // nillable struct field.
Optional bool // nullable field in database.
Immutable bool // create-only field.
Default interface{} // default value on create.
UpdateDefault interface{} // default value on update.
Validators []interface{} // validator functions.
StorageKey string // sql column or gremlin property.
Enums []struct{ N, V string } // enum values.
Sensitive bool // sensitive info string field.
SchemaType map[string]string // override the schema type.
Annotations []Annotation // field annotations.
// contains filtered or unexported fields
}
A Descriptor for field configuration.
func (*Descriptor) Err ¶
func (d *Descriptor) Err() error
Err returns the error, if any, that was added by the field builder.
type EnumValues ¶
type EnumValues interface {
Values() []string
}
EnumValues defines the interface for getting the enum values.
type RType ¶
type RType struct {
Name string
Kind reflect.Kind
PkgPath string
Methods map[string]struct{ In, Out []*RType }
}
RType holds a serializable reflect.Type information of Go object. Used by the entc package.
type Type ¶
type Type uint8
A Type represents a field type.
const ( TypeInvalid Type = iota TypeBool TypeTime TypeJSON TypeUUID TypeBytes TypeEnum TypeString TypeInt8 TypeInt16 TypeInt32 TypeInt TypeInt64 TypeUint8 TypeUint16 TypeUint32 TypeUint TypeUint64 TypeFloat32 TypeFloat64 )
List of field types.
func (Type) ConstName ¶
ConstName returns the constant name of a info type. It's used by entc for printing the constant name in templates.
type TypeInfo ¶
type TypeInfo struct {
Type Type
Ident string
PkgPath string
Nillable bool // slices or pointers.
RType *RType
}
TypeInfo holds the information regarding field type. Used by complex types like JSON and Bytes.
func (TypeInfo) Comparable ¶
Comparable reports whether values of this type are comparable.
func (TypeInfo) ValueScanner ¶
ValueScanner indicates if this type implements the ValueScanner interface.
