示例1: PrimaryField
// PrimaryField return gorm's primary field
func (res *Resource) PrimaryField() *gorm.Field {
if res.primaryField == nil {
scope := gorm.Scope{Value: res.Value}
res.primaryField = scope.PrimaryField()
}
return res.primaryField
}示例2: afterUpdate
func afterUpdate(scope *gorm.Scope) {
if !scope.HasError() {
if isLocalizable(scope) {
if locale, ok := getLocale(scope); ok {
if scope.DB().RowsAffected == 0 && !scope.PrimaryKeyZero() { //is locale and nothing updated
var count int
var query = fmt.Sprintf("%v.language_code = ? AND %v.%v = ?", scope.QuotedTableName(), scope.QuotedTableName(), scope.PrimaryKey())
// if enabled soft delete, delete soft deleted records
if scope.HasColumn("DeletedAt") {
scope.NewDB().Unscoped().Where("deleted_at is not null").Where(query, locale, scope.PrimaryKeyValue()).Delete(scope.Value)
}
// if no localized records exist, localize it
if scope.NewDB().Table(scope.TableName()).Where(query, locale, scope.PrimaryKeyValue()).Count(&count); count == 0 {
scope.DB().Create(scope.Value)
}
}
} else if syncColumns := syncColumns(scope); len(syncColumns) > 0 { // is global
if mode, _ := scope.DB().Get("l10n:mode"); mode != "unscoped" {
if scope.DB().RowsAffected > 0 {
var primaryField = scope.PrimaryField()
var syncAttrs = map[string]interface{}{}
if updateAttrs, ok := scope.InstanceGet("gorm:update_attrs"); ok {
for key, value := range updateAttrs.(map[string]interface{}) {
for _, syncColumn := range syncColumns {
if syncColumn == key {

break
}
}
}
} else {

}
scope.Err(db.UpdateColumns(syncAttrs).Error)
}
}
}
}
}
}
}示例3: Stringify
// Stringify stringify any data, if it is a struct, will try to use its Name, Title, Code field, else will use its primary key
func Stringify(object interface{}) string {
if obj, ok := object.(interface {
Stringify() string
}); ok {
return obj.Stringify()
}
scope := gorm.Scope{Value: object}
for _, column := range []string{"Name", "Title", "Code"} {
if field, ok := scope.FieldByName(column); ok {
return fmt.Sprintf("%v", field.Field.Interface())
}
}
if scope.PrimaryField() != nil {
if scope.PrimaryKeyZero() {
return ""
}
return fmt.Sprintf("%v#%v", scope.GetModelStruct().ModelType.Name(), scope.PrimaryKeyValue())
}
return fmt.Sprint(reflect.Indirect(reflect.ValueOf(object)).Interface())
}
