Hello everybody,<br />I have a requirement related to this thread, i want to change the storage table of my form, i&#39;m using Liferay 7.2. I tried to implement the StorageAdapter interface but all my imported classes are deprecated, in addition to this building and deploying my service to my server didn&#39;t add the storage option in the form settings.

Not sure that&#39;s going to be possible there; the expectation is that code will persist the form, not really reject form data.<br /><br /><br /><br /><br /><br /><br /><br /><a href="https://www.eventbrite.com/e/liferay-symposium-north-america-2017-registration-28398031276">Come meet me at the 2017 LSNA!</a>

Hi David ,<br /><br />Thanks for the reply.<br />So i can persist the data entered in form into a separate database.<br />Also can you let me know if i can apply some business rules on the form like if i have a field weight - can i apply a business rule like weight should not exceed 100 kg upper limit at front end and also at backend?

No modifications necessary.<br /><br />Just create an implementation of the com.liferay.dynamic.data.mapping.storage.StorageAdapter. When creating your form, you can select this storage adapter for the form.<br /><br />Your storage adapter can then do anything to persist and access the data. Check out the com.liferay.dynamic.data.mapping.storage.impl.JSONStorageAdapter to see how to serialize to/from json and how the Liferay implementation handles the persistence.<br /><br /><br /><br /><br /><br /><br /><a href="https://www.eventbrite.com/e/liferay-symposium-north-america-2017-registration-28398031276">Come meet me at the 2017 LSNA!</a>

Hi All<br /><br />I have a use case where i am required to save the form data - json -to a separate db rather than liferay db.<br />For this use case i figured out that Liferay 7 forms can be used but my use case is little different due to above scenario.<br />Can we still use liferay 7 forms with some modification ?
