OpenUI5 ui advancing

Hamza and I had a hangouts session where we dived into the delete action using OpenUI

What to do after deleting a record? The current behaviour in ExtJS is more or less mature, and something similar seems okay for OpenUI as well: Remain in the detail window and go to the next row. If this was the last row of the table, go to the previous row. If the table has become empty (no more records), close the detail window after displaying a suitable message. We explored an edge case of the DeleteSelected action : in lydia demo project (Lino Tera), the detail layout for life groups is different to the detail layout of an individual therapy (“life group” and “individutal” therapy are two choices in the CourseAreas choicelist). This logic is defined by lino_xl.lib.courses.Course.get_detail_action(). If I open “Therapies held by me” (or “Therapies managed by me”), Lino shows a mixture of therapies from different course areas. The detail layout to use depends on the current row. If I go to the detail view and delete one of them, Lino must potentially “switch to another layout”.

How to implement this behaviour, depends on the user interface. The DeleteSelected action should just delete the record and return success-or-not.

The detail_handler_name key in the action response of DeleteSelected is rather a hack used for ExtJS. It means “in case you are in detail view, I remind you the name of the current detail view”. I think we should try to not use this in openui and instead have it remind that name itself.

grid.changes.ChangesByMaster was not available as a route because the controller defined only master reports. Seems that there must also be a route for slave tables. You must change what Lino returns in eval_js. This is easily done, you just need to override the request_handler() method and the instance_handler() method of the OpenUI renderer. Currently you let Lino return a string like “Lino.grid.changes.ChangesByMaster(…)”, then the JS client modifies this string and defines a wrapper function window_action()… but all this is not needed if you so that they return the “openui5 js implementation” for that action.

Lino Tera continued

I continued to work on #2162 for Lino Tera.

  • Status der importierten Anwesenheiten ist immer leer. Status “Verpasst” heißt “abwesend” in Lino.

In Lino Tera we have an additional field “Payment mode” (Zahlart) with four values:

B Bar           Cash (paid)
Z Zu kassieren  Cash to pay
R Rechnung      Invoice
G Kostenlos     Free

In TIM this field was on both cal.Event and cal.Guest, but I guess that in Lino we will put it only on cal.Guest because on Event it was rather a fallback value for the field on Guest.

This field might be useful for other applications. Of course not for Welfare and Avanti because the clients don’t pay there. In Voga the clients do pay, but we also don’t want it because in Voga they always get an invoice. This field is needed only when the course leaders have their individual “decentralized” accounting which enables cash payments by the clients. Cash payments introduce additional complexity because the course leaders must introduce the collected money into the central accounting system. So actually next to payment_mode we also have two more fields amount_to_pay and amount_received.

  • Wird das bisherige System mit der Kassenverwaltung durch Therapeuten beibehalten?
