It took me some time to figure out, how I can provide a label for an action parameter.
I try to separate all my translations in label.cds file. This means, the annotations are not placed where the entities or actions are defined. If you have the action definition and the label annotations in one file, you could simply do the following for an action:
trip-service.cds
entity Trip as projection on db.Trip
actions {
action approval();
action rejection(reason: String @title: '{i18n>reason});
};
But if you separate both, you need to access somehow the defined action to add the annotation. Following a short snippet, how it works. The important part is, that you have to write a complete new annotation block for your actions.
trip-service.cds without label
service tripService @(requires: 'authenticated-user') {
entity Trip as projection on db.Trip
actions {
action approval();
action rejection(reason: String);
};
}
label.cds
using my.namespace as db from '../db/index';
using tripService from '../srv/trip-service';
annotate db.Trip with @title: '{i18n>trips}' {
description @title : '{i18n>description}';
status @title : '{i18n>status}';
// etc.
}
// solution
annotate tripService .Trip actions {
rejection(reason @titlel: '{i18n>reason}' )
}
