A pywhich command

Here is a pywhich command defined in my .bash_aliases:

function pywhich() {
  python -c "import $1; print $1.__file__"

“Model %(model)s with pk %(pk)r does not exist.”

I submitted Django ticket #20791. Yes this is nit-picky but I happen to see that message rather often when loading a backup in which north.dpy has to defer instances.

Released Lino-Welfare 1.1.8

I released Lino-Welfare 1.1.8.

Determine project interdependencies: The last release (1.1.7) was 2013-06-04. By consulting the diffs of the changelogs, I saw that atelier, djangosite and north had no runtime-relevant changes since that date. Lino the framework does have.


released version

needs update?
















I increased the version numbers already some time ago.

On prodsite, stop services and make a backup:

$ cd /usr/local/django/prod
$ ./stop
$ ./backup
$ ls -l /var/log/lino/backups/b20130723*.py
-rw-r--r-- 1 www-data www-data 23781742 Jul 23 02:02 /var/log/lino/backups/b20130723_020101.py

Import that backup to testlino after pulling the latest development versions:

$ pull
$ cd /usr/local/django/test
$ . env/bin/activate
$ python manage.py initdb --traceback b20130723_020101

On my machine, create sdist for lino and welfare and publish them to http://www.lino-framework.org/dl:

$ go welfare
$ fab sdist
$ go lino
$ fab sdist
$ fab docs pub

On prodsite, upgrade prod using pip –extra-index-url:

$ cd /usr/local/django/prod
$ . env/bin/activate
$ pip install -U --extra-index-url=http://www.lino-framework.org/dl lino-welfare
$ python manage.py initdb --traceback b20130723_020101

Noted that this also upgraded appy from 0.8.3 to 0.8.4 and docutils from 0.10 to 0.11. Just in case of surprises…

This means that also djangosite needs a release.

On my machine, create sdist for site and publish it to http://www.lino-framework.org/dl:

$ go site
$ fab sdist
$ go lino
$ fab docs pub

On prodsite, upgrade prod once more using pip –extra-index-url:

$ cd /usr/local/django/prod
$ pip install -U --extra-index-url=http://www.lino-framework.org/dl lino-welfare
$ python manage.py initdb --traceback b20130723_020101

After some more changes (which show that it is important to test using sdist before officially releasing on PyPI) I finally did it: I officially relased

  • djangosite 0.1.6

  • lino 1.6.11

  • lino_welfare 1.1.8

New module lino.modlib.attestations

welfare.receptions is not yet fully functional, but my brain is already preparing the next steps: There will be a new module lino.modlib.attestations. An “attestation” is an “official” document which attests (confirms) something. Part of the current lino_welfare.modlib.notes will move there. Notes are just “internal notes”, but a CV is rather such an attestation.

Acting as another user

Discovered and fixed a first bug in the freshly released Lino 1.6.11: Acting as somebody else didn’t work when calling it while in the main viewport.

Übersicht Art-60§7-Konventionen

Two more bugs fixed:

  • Übersicht Art-60§7-Konventionen : wenn man im Parameter-Panel eine Stellenart auswählte, kam Fehlermeldung “‘JobType’ object is not iterable”

  • Übersicht Art-60§7-Konventionen : Vorschau ist leer. Da kam stattdessen eine Fehlermeldung in der JS-Console, weil das Fenster keinen Navigator hatte und dennoch versuchte, die Navigationsbuttons zu deaktivieren.

Klientenansicht “Empfang”

New Reception ‣ Clients shows a welfare.reception.Clients table with simplified columns and detail which does not inherit from the “usual” welfare.pcsw.Clients table.
