SmartClient: SNAPSHOT_v9.1d_2013-09-08
Firefox 23.0.1
Client side-data-integration
New to SmartClient, so far looks very very nice, just a little trouble getting started.
I am using OrientDB as backend db/rest server and can't modify the format to use the RestDataSource to I am trying to convert the data sent back to the server to the correct format.
After calling form.saveData() I am using the transformRequest to manipulate the data before I post the update back to the server, however I do not know how to extract the changed values from the dsRequest.data, the data object contains all of the unmodified fields as well as the modified ones and I need to just send back the record id with just the modified values
I know the form object has getChangedValues() which works like I want it to but after calling saveData() and once I am in the transformRequest the dsRequest does not have a ChangedValues method.
Here is the data that I receive from my server
This data is bound to a grid that upon row selection sets the form values to current selected row
The update record posted to the server should look like
I have no problems creating a new javascript object like the one above, but I don't know how to get the changed values from the dsRequest.data
Here is my test code
Also is this the correct approach for connecting to a Rest API versus overriding the built in RestDataSource, I think the docs said this was the correct approach, but just want to confirm. After I get this working then I should be able to extend the DataSource class to include the necessary modifications to communicate to my server, any examples of other users making a custom js DataSource class to a custom rest server?
Thanks for any help,
Dan
