Code Camp in Vigala

After reading an invitation to participate to the European CodeWeek (Üleeuroopaline programmeerimisnädal Code Week by HITSA, the Foundation for ICT related education development in Estonia), I had problems to hold back my ideas, so I published them: Vigala Code Camps are coming up

And I also registered this to the CodeWeek calendar.

Lino Voga

  • Minor optimizations in Lino Voga for #919.

  • Courses.quick_search_fields = “pupil__name”

Internal change about quick search fields

I made a small change in lino.core.dbtables: Converted the add_quick_search_filter function into a class method on the actor:

This requires also a changed call in lino.modlib.extjs.views and lino_extjs6.extjs.views.

Community page and Teamwork Guide

I worked (for #309) on the community page and moved the Individual contributors section from Lino Noi to Developer Guide.

Error during openpyxl_shutdown

The Lino Welfare test suite runs without failures, but I get a traceback during atexit:

Ran 51 tests in 197.162s

INFO Done setup.py -q test (PID 9219)
INFO:lino.core.kernel:Done setup.py -q test (PID 9219)
Error in atexit._run_exitfuncs:

    for path in ALL_TEMP_FILES:

Error in sys.exitfunc:

    for path in ALL_TEMP_FILES:

Actually this looks like a bug in openpyxl. Maybe we should report it. Do we forget to close a temporary file? I avoided the traceback by moving the from openpyxl statements into the ExcelRenderer.render() method.

More optimizations for Lino Voga

  • Einschreibungen pro Kurs : Am Bildschirm steht jetzt wieder nur der Name des Teilnehmers

  • Statusbericht : Statt der Kolonne “Einschreibungen” haben wir jetzt zwei Kolonnen “Angefragt” und “Bestätigt”. Beide Kolonnen zeigen jetzt nur noch aktive Einschreibungen an. Habe auch die Reihenfolge dieser Kolonnen angepasst (scheint mir jetzt logischer)

  • Ausdruck Anwesenheitsblatt : hier werden jetzt nur aktive Teilnehmer (in der angegebenen Periode) gedruckt

A change in linoweb.js

I discovered that the new keep_user_values attribute of an action did require a subtle change in linoweb.js, Lino.ActionFormPanel.add_field_values(): Until now this tested whether the form is dirty, and if not, submitted only the original field values which had been set by set_status(). But now status_field_values can be empty when Action.keep_user_values is True. In that case we must submit the current values even if the form is not dirty. I don’t remember why we had this feature of not submitting unmodified field values, so I remove this feature for now. So from today, action parameter windows always submit all field values, even if the user did not change anything.

I did the same modification in the linoweb.js for lino_extjs6 as well.
