Is there a way to re-use the validation rules applied to some fields in Salesforce to a Visualforce page automaticaly?
I have a CustomController right now supporting the saving process of a field, but some required fields in the default object are not required in the Visualforce (unless I set them manually).
Thanks.
The response will return the API Name of the field in the "fields" array of the response. But only if the Error Location of the Validation Rule is configured correctly.
The Field needs to be selected from the picklist when creating (or modifying) the validation rule. This is shown in the screenshot below
When I violate the example validation rule above, my json response is:
[ {
"fields" : [ "BillingCity" ],
"message" : "This Billing City is a bad choice, please select another.",
"errorCode" : "FIELD_CUSTOM_VALIDATION_EXCEPTION"
} ]
So as long as the Error Location on each Validation Rule is specified as 'Field', you will be able to place the error message next the right field in your mobile app.
You need to turn off immediate and adjust or disable your validation rules.
Both issues you're having are related to the immediate=true parameter on the action function. This parameter forces the action function to run immediately without running (1) any getters/setters, and (2) any front-end validations.
For (1), since the getters and setters aren't run, none of the field changes make it back to your controller. Hence the record you're saving doesn't include any of the new input.
For (2), you're only bypassing front-end validations, specifically fields you've marked as required in the visualforce page. Validation rules are ALWAYS run no matter what, you can't turn them off. You'll need to disable them or adjust them so they don't apply to new records.

Validation Rules only execute when a database commit occurs (update/ insert/ upsert)
You cannot explicitly reference Validation Rules in Visualforce.
However you can logic you've already written in Validation Rules by including the apex:pageMessages tag in your VisualForce page, and letting the validation rules kick in on save - if any failures occur, they will be displayed on the VisualForce page.
