does gii automatically create relations for generated models?

阅读更多关于 does gii automatically create relations for generated models?

问题 I'm new to Yii here. In the documentation, it seems to imply that gii will create the relations for related models. But when using gii to generate models from DB, it doesn't seem to be the case.

Did I do something wrong, or gii just doesn't automatically recognize the relations? Thanks, 回答1: Gii will create relations for MyISAM tables if you
