推荐答案

仅当您在表单设置中创建新表单时才能更改存储类型. JSON类型是默认类型，但是您可以创建一个新的StorageAdapter来创建其他类型.

You can change the storage type only when you are creating a new form in the form settings. The JSON type is the default but you can create a new StorageAdapterto create additional types.

看看

Have a look at the JSONStorageAdapter to get an inspiration how to develop a custom one. Should be enough to create a bundle put the new class in. Extend the BaseStorageAdapter and implement new necessary methods.

新类将在部署后提取，您应该在表单"设置中获得一个新选项.

The new class will be picked up after deployment and you should get a new option in the Form settings.
