Story Points:1
Use case
- As a developer building an application based on Web UI, I want to be sure the content of a document creation / edit form is validated server-side so that my content integrity is ensured.
Example: make sure that my end date property for a Contract document type is ulterior to my start date property (see NXDOC-1578 ).
Currently I can easily validate the form client side, but have no way to configure the same check server-side using Studio.
- I can add an event handler on document creation / modification
- I can bind it to an automation script
But the script cannot throw a NuxeoException if the rule is not ok.
I would like to do the following to complete my use case:
throw new NuxeoException("End date must be ulterior to start date", 400);
WHAT HAPPENS CURRENTLY
- Whitelist NuxeoException using an XML extension
<require>org.nuxeo.automation.scripting.classfilter</require> <extension target="org.nuxeo.automation.scripting.internals.AutomationScriptingComponent" point="classFilter"> <classFilter> <allow>org.nuxeo.ecm.core.api.NuxeoException</allow> </classFilter> </extension> - Create an automation script with the following content:
function run(input, params) { throw new org.nuxeo.ecm.core.api.NuxeoException("FooBar3000"); } - Associate it to an event handler on about to create and before doc modification
- Save, deploy and create a new doc
