Functions

func CopyFields

func CopyFields(dst, src interface{}) (err error)

CopyFields copies matching struct/array/slice fields that implement the Value interface from src to dst. Matching is done by comparing the MetaData.Selector() of the fields. Copying is done by calling SetString() of dst with the result from String() of src. This way even not exactly matching models can be copied by converting to and from strings if this is possible without errors.

func CopyFieldsIfNotEmpty

func CopyFieldsIfNotEmpty(dst, src interface{}) (err error)

CopyFieldsIfNotEmpty copies matching struct/array/slice fields that implement the Value interface from src to dst, if IsEmpty() of src returns false. Matching is done by comparing the MetaData.Selector() of the fields. Copying is done by calling SetString() of dst with the result from String() of src. This way even not exactly matching models can be copied by converting to and from strings if this is possible without errors.

Multiple attributes are separated by '|'. Example:

type Struct {
