package models

import (
	"encoding/json"
	"errors"
	"fmt"
	"strconv"
)

type Boolean bool

func (st *Boolean) UnmarshalJSON(b []byte) error {
	var item interface{}
	if err := json.Unmarshal(b, &item); err != nil {
		return err
	}
	switch v := item.(type) {
	case bool:
		*st = Boolean(v)
	case int, uint:
		if v == 1 {
			*st = true
		} else {
			*st = false
		}
	}
	return nil
}

func (st *Boolean) Scan(value interface{}) error {
	data := 0
	switch v := value.(type) {
	case []byte:
		str, err := strconv.ParseInt(string(v), 10, 8)
		if err != nil {
			return errors.New(fmt.Sprint("Failed to unmarshal JSON value:", value))
		}
		data = int(str)
	case int64:
		data = int(v)
	}

	if data == 1 {
		*st = true
	} else {
		*st = false
