PHP RedBeanModel::getDerivedRelationType方法代码示例

 /**
  * Notice the use of $modelToForgetCache. This was needed to avoid a caching issue with the following example.
  * If an opportunity fires, and a related account's opportunity is created. This new opportunity had a cached
  * model for account that was null.  So this is fixed by forgetting the new model after it is added to the account.
  * @throws FailedToSaveModelException
  * @throws NotSupportedException
